1. Introduction: Turkey’s Strategic Position and Zero-Tolerance Drug Policy

Turkey occupies a unique and strategically sensitive position within global narcotics trafficking routes. Situated between major drug-producing regions in the Middle East, Central Asia and South America, and high-consumption markets in Europe, Turkey has long functioned both as a transit corridor and, increasingly, as a destination market. This geographic reality has profoundly shaped Turkey’s criminal policy on narcotic drugs and explains the consistently strict approach adopted by the legislature, law-enforcement authorities and the judiciary.

Narcotic drug offences under Turkish law are not treated as ordinary crimes against public order but as serious threats to public health, social stability and national security. This perception is reflected in the structure of the Turkish Penal Code, where offences relating to narcotic and psychotropic substances are regulated under a dedicated and comprehensive framework (TPC Articles 188-192). The penalties prescribed for production, import, export and trafficking rank among the heaviest sanctions in Turkish criminal law, often comparable to those imposed for organized crime and terrorism-related offences.

Turkey’s zero-tolerance policy is not merely a product of domestic criminal policy choices. It is also the result of binding international obligations arising from multilateral drug control treaties, particularly the 1961 Single Convention on Narcotic Drugs and the 1988 United Nations Convention against Illicit Traffic in Narcotic Drugs and Psychotropic Substances. These instruments require States Parties to criminalize a broad range of drug-related conduct, ensure effective enforcement mechanisms, and engage in international cooperation through extradition, mutual legal assistance and joint operations. Turkish legislation and judicial practice have consistently interpreted domestic law in light of these international commitments.

An important characteristic of Turkish narcotics law is its uniform application to all persons within Turkish jurisdiction. Citizenship does not operate as a mitigating or differentiating factor. Turkish nationals and foreign nationals are subject to the same substantive criminal provisions, procedural rules and sentencing principles. This has particular practical significance for tourists, expatriates and foreign residents, many of whom encounter serious legal consequences due to assumptions based on the legal status of certain substances in their home countries. Substances such as cannabis, khat or prescription-based narcotics, which may be tolerated or decriminalized elsewhere, are strictly regulated or entirely prohibited under Turkish law, and ignorance of the law does not preclude criminal liability.

Beyond individual criminal liability, Turkey has developed an extensive regulatory regime governing the lawful handling of narcotic and psychotropic substances by corporate actors. Companies operating in the pharmaceutical, healthcare, chemical and logistics sectors are subject to layered licensing, reporting and security obligations administered primarily by the Ministry of Health. Breaches of these regulatory duties may give rise not only to administrative sanctions but also to criminal liability for both legal entities and responsible individuals. As a result, narcotics law in Turkey operates at the intersection of criminal enforcement and regulatory compliance.

This article aims to provide a structured and comprehensive legal overview of narcotic drug offences in Turkey, with particular attention to the classification of offences, enforcement practices, judicial interpretation and practical risks. It also addresses the specific implications for foreign nationals and corporate actors, drawing on statutory provisions, Yargıtay (Court of Cassation) case law and recent enforcement trends. By situating Turkish narcotics law within its domestic and international context, the analysis seeks to offer a clear reference framework for individuals, companies and practitioners navigating one of the most rigorously enforced areas of Turkish criminal law.

2. Legal Sources Governing Narcotic Drug Offences in Turkey

The legal regulation of narcotic drug offences in Turkey rests on a multilayered normative framework composed of domestic criminal legislation, secondary regulatory instruments, and binding international conventions. This structure reflects both Turkey’s internal criminal policy priorities and its obligations under international drug control regimes. Understanding the interaction between these sources is essential for accurately assessing criminal liability, enforcement practices, and judicial interpretation.

2.1. Turkish Penal Code as the Primary Legal Source

At the core of Turkey’s narcotics regime lies the Turkish Penal Code No. 5237 (TPC). Drug-related offences are primarily regulated under Articles 188 to 192, which collectively establish a comprehensive typology of criminal conduct involving narcotic and psychotropic substances. Unlike systems that disperse drug offences across multiple statutes, Turkish law concentrates these offences within a single, systematically constructed section of the Penal Code, thereby emphasizing their gravity and coherence.

Article 188 constitutes the cornerstone of this framework. It criminalizes the production, import, export, sale, supply, distribution, and brokerage of narcotic or psychotropic substances without authorization. The legislator deliberately employs broad language to capture both direct perpetrators and intermediaries, ensuring that all functional roles within the drug trade fall within the scope of criminal liability. The severe penalty ranges prescribed under Article 188 – particularly for production and cross-border trafficking – underscore the legislature’s intent to treat such conduct as a serious threat to public order and public health.

Article 191 addresses possession and acquisition for personal use, reflecting a differentiated approach between users and traffickers. While possession for personal consumption remains a criminal offence, Turkish law introduces rehabilitative mechanisms such as deferred prosecution, probation and mandatory treatment, especially for first-time offenders. This dual-track structure illustrates a policy choice that combines deterrence with public health considerations, without fully decriminalizing drug use.

Article 190 targets conduct that facilitates or encourages drug use by others, such as providing premises for consumption or otherwise enabling access. This provision plays a critical role in bridging the gap between use-related offences and commercial trafficking, allowing courts to sanction indirect contributions to the spread of narcotics even where no sale or distribution can be proven.

Finally, Article 192 introduces mitigation mechanisms, particularly for offenders who provide effective cooperation with authorities. This reflects a pragmatic enforcement strategy aimed at dismantling drug networks by incentivizing insider cooperation, a practice frequently endorsed by Turkish courts in complex trafficking cases (Yargıtay 10. Ceza Dairesi, E. 2016/2855, K. 2016/7429).

2.2. Secondary Legislation and Regulatory Instruments

While the Turkish Penal Code defines the criminal offences themselves, secondary legislation plays a crucial complementary role in regulating lawful activities involving controlled substances. Various regulations issued by the Ministry of Health govern the production, import, export, storage and distribution of narcotic and psychotropic substances for medical and scientific purposes. These regulations define licensing requirements, reporting obligations, security standards and inspection mechanisms. Non-compliance with regulatory obligations may trigger administrative sanctions such as fines, suspension or revocation of licenses. However, where violations involve diversion, concealment or intentional misuse of controlled substances, criminal liability under the Penal Code may also arise. Turkish courts frequently assess regulatory breaches as evidentiary indicators of criminal intent, particularly in cases involving pharmaceutical companies or logistics operators accused of facilitating illicit drug flows.

2.3. International Drug Control Conventions and Their Domestic Effect

Turkey is a party to the principal international drug control treaties, including the 1961 Single Convention on Narcotic Drugs, the 1971 Convention on Psychotropic Substances, and most significantly, the 1988 United Nations Convention against Illicit Traffic in Narcotic Drugs and Psychotropic Substances. These conventions impose obligations on States Parties to criminalize drug-related conduct, adopt effective enforcement measures, and cooperate internationally through extradition, mutual legal assistance and asset confiscation mechanisms. The 1988 Vienna Convention has had a particularly strong influence on Turkish narcotics law. Its emphasis on cross-border trafficking, organized crime involvement and international cooperation is closely mirrored in the structure and interpretation of Article 188 TPC. Turkish courts routinely refer, either explicitly or implicitly, to the objectives of the Vienna Convention when interpreting ambiguous provisions, especially in cases involving international trafficking networks or foreign defendants.

From a constitutional perspective, international treaties duly ratified by Turkey have the force of law, and where conflicts arise concerning fundamental rights, international treaty provisions prevail over domestic statutes (Article 90 of the Turkish Constitution). Although narcotics conventions primarily impose obligations on states rather than directly conferring individual rights, their normative influence on legislative drafting and judicial reasoning remains significant.

2.4. Interaction Between Domestic and International Sources

The interaction between domestic criminal law and international obligations produces a legal environment in which Turkish courts are both empowered and constrained. On the one hand, Turkey is required to maintain strict criminalization and robust enforcement against narcotics offences. On the other hand, enforcement must remain consistent with international legal principles governing jurisdiction, proportionality and cooperation.

This interaction becomes particularly visible in cases involving foreign nationals, cross-border trafficking and extradition requests. Turkish courts and prosecutors must navigate not only the substantive provisions of the Penal Code but also Turkey’s treaty obligations and diplomatic commitments. As a result, narcotic drug offences in Turkey cannot be fully understood in isolation from their international legal context; they operate within a transnational legal ecosystem that shapes both legislative design and judicial practice.

3. Classification of Narcotic Drug Offences under Turkish Law

Turkish narcotics law adopts a functional and conduct-based classification of drug-related offences. Rather than relying on a single, monolithic offence definition, the Turkish Penal Code differentiates criminal liability according to the nature of the act, its purpose, the scale of activity and its impact on public health. This classification is central to both charging decisions and judicial assessment, as the distinction between use-related conduct and commercial trafficking directly affects penalties, procedural treatment and sentencing outcomes.

3.1. Production, Import and Export of Narcotic Drugs (TPC Article 188/1)

Article 188/1 criminalizes the unauthorized production, manufacture, import and export of narcotic or psychotropic substances. These acts are regarded as the most serious drug offences under Turkish law due to their systemic impact and cross-border character. The penalty range, imprisonment from twenty to thirty years accompanied by substantial judicial fines, reflects the legislature’s assessment that such conduct constitutes a direct threat to public order and international security.

In judicial practice, the concept of “production” is interpreted broadly. It encompasses not only large-scale industrial manufacturing but also any technical process that transforms raw materials into consumable narcotic substances. Courts focus on whether the accused exercised control over the production process, regardless of scale or sophistication (Yargıtay 10. Ceza Dairesi, E. 2016/2855, K. 2016/7429). Import and export offences are considered completed once the act of crossing the customs boundary occurs or, in certain circumstances, once the customs declaration is submitted with the intent to introduce or remove narcotics from Turkish territory. Even if the substance is intercepted at the border, courts may treat the offence as completed rather than attempted, depending on the factual circumstances and the degree of control exercised by the offender (Yargıtay 20. Ceza Dairesi, E. 2017/6864, K. 2017/6864). The extraterritorial dimension of these offences also plays a role in jurisdictional analysis, particularly in cases involving transit shipments or international trafficking networks. Turkish courts consistently emphasize the international obligations arising from the 1988 Vienna Convention when interpreting Article 188/1 in such contexts.

3.2. Domestic Drug Trafficking, Sale and Supply (TPC Article 188/3)

Article 188/3 regulates the domestic sale, supply, distribution, delivery and brokerage of narcotic substances within Turkey. While the penalties prescribed – ten to twenty years of imprisonment -are lower than those for production or import/export, they remain among the most severe sanctions in the Turkish criminal justice system.

A recurring issue in practice is the distinction between trafficking and possession for personal use. Turkish courts reject a purely quantitative approach. While the amount of the substance is relevant, it is not decisive. Instead, courts evaluate a combination of factors, including packaging method, possession of scales or distribution tools, communication records, prior conduct, and the presence of multiple buyers or intermediaries (Yargıtay 20. Ceza Dairesi, E. 2017/6864, K. 2017/6864).

Intermediaries and facilitators are treated as principal offenders under Article 188/3. Acting as a broker, courier or intermediary between buyer and seller suffices to establish liability, even if the accused does not physically possess the drugs at the time of arrest. This expansive interpretation aims to prevent circumvention of criminal liability through compartmentalized roles within trafficking networks.

3.3. Possession and Use for Personal Consumption (TPC Article 191)

Article 191 addresses the purchase, receipt or possession of narcotic substances for personal use. While this conduct remains criminalized, Turkish law adopts a differentiated approach that prioritizes rehabilitation over punishment, particularly for first-time offenders. The offence carries a statutory penalty of two to five years of imprisonment. However, in practice, courts frequently apply deferred prosecution mechanisms, probation and mandatory treatment programs. If the accused complies with treatment and supervision conditions, prosecution may be suspended or ultimately dismissed.

Judicial scrutiny in Article 191 cases focuses heavily on evidentiary sufficiency. Courts require objective evidence, such as seized substances or forensic reports, and consistently reject convictions based solely on uncorroborated confessions (Yargıtay 10. Ceza Dairesi, E. 2018/5513, K. 2018/9413). This approach reflects a cautious stance aimed at preventing wrongful convictions in low-level drug cases.

3.4. Facilitation of Drug Use (TPC Article 190)

Article 190 criminalizes acts that facilitate or encourage the use of narcotic substances by others. This includes providing premises for consumption, enabling access to drugs, or otherwise promoting use without directly engaging in sale or distribution. The offence occupies a transitional space between personal use and trafficking. Courts assess whether the accused’s conduct materially contributed to the spread of drug use, even in the absence of financial gain. The penalty range, five to ten years of imprisonment, underscores the legislature’s intention to sanction indirect contributions to narcotics consumption that undermine public health. Judicial interpretation emphasizes the contextual assessment of facilitation. Occasional or incidental conduct may not suffice, whereas systematic or organized facilitation is treated as a serious offence approaching trafficking in gravity.

3.5. Unauthorized Cannabis Cultivation

Unauthorized cultivation of cannabis constitutes a distinct offence under Turkish law, separate from production or trafficking. Courts distinguish between licensed industrial hemp cultivation, which is subject to strict administrative authorization, and illicit cultivation intended for narcotic use. Even small-scale cultivation may attract criminal liability if the intent to produce narcotic substances can be inferred from the circumstances. Factors such as concealment methods, quantity of plants, and absence of lawful authorization are decisive in judicial assessment (Yargıtay 10. Ceza Dairesi, E. 2013/12973, K. 2015/1472).

3.6. Aggravating Circumstances Across Drug Offences

Across all categories of narcotic drug offences, certain aggravating factors significantly enhance penalties. These include commission of the offence within proximity to protected locations such as schools or hospitals, involvement of minors, use of organized criminal structures, and the nature of the substance involved. Courts apply these aggravations strictly, often resulting in sentence enhancements beyond the base penalty range (Yargıtay 10. Ceza Dairesi, E. 2013/12973, K. 2015/1472).

4. Aggravating Circumstances and Sentence Enhancements

Turkish narcotics law does not limit criminal liability to the base definitions of drug-related offences. Instead, the Turkish Penal Code adopts a structured system of aggravating circumstances that significantly enhance penalties when certain qualitative or contextual factors are present. These aggravations reflect the legislature’s assessment that some forms of narcotic crime pose heightened risks to public health, social order and vulnerable groups. In judicial practice, the application of aggravating circumstances often determines not only the length of imprisonment but also the overall classification of the offence within the sentencing hierarchy.

4.1. Proximity to Protected and Sensitive Locations

One of the most consistently applied aggravating factors concerns the commission of drug offences in close proximity to protected locations. Article 188 expressly provides for enhanced penalties where narcotic offences are committed within a defined distance of schools, dormitories, hospitals, military facilities, places of worship or similar public institutions. Turkish courts interpret this aggravation as an objective, spatial criterion. The offender’s intent to target minors or vulnerable individuals is not required. It is sufficient that the act of sale, supply or distribution occurs within the legally prescribed distance. Yargıtay has repeatedly held that the mere geographical proximity to a protected area automatically triggers the aggravating clause, regardless of whether the drugs were actually sold to students or patients (Yargıtay 10. Ceza Dairesi, E. 2013/12973, K. 2015/1472). Comparatively, this approach is stricter than that adopted in many jurisdictions, where proof of intent to exploit vulnerable populations is required. Turkish law, by contrast, prioritizes preventive protection of sensitive zones, even at the cost of broader criminal liability.

4.2. Involvement of Organized Criminal Structures

Participation in organized criminal activity constitutes one of the most severe aggravating factors across all narcotic offences. Where drug-related conduct is carried out within the framework of an organized group, penalties may be doubled. Turkish courts assess organization based on continuity, hierarchical structure and division of roles, rather than formal membership alone. Judicial practice demonstrates a low tolerance for compartmentalized roles designed to evade liability. Couriers, intermediaries and logistical facilitators are frequently classified as members of an organized structure if their actions display continuity and coordination. In such cases, courts emphasize the collective danger posed by organized drug networks and impose substantially higher sentences (Yargıtay 10. Ceza Dairesi, E. 2016/2855, K. 2016/7429). From a comparative perspective, Turkish law aligns with international trends under the 1988 Vienna Convention, which encourages States to treat organized drug trafficking as an aggravated form of criminal conduct. However, Turkish courts tend to apply this aggravation more expansively than some European jurisdictions, particularly with respect to informal or loosely structured groups.

4.3. Nature and Potency of the Narcotic Substance

The type of narcotic substance involved plays a critical role in sentencing. Turkish courts distinguish between substances based on their addictive potential, health risks and prevalence in organized trafficking. Offences involving heroin, cocaine, synthetic cannabinoids and similar high-risk substances attract enhanced penalties, even where the quantity involved is relatively limited. Judicial reasoning frequently emphasizes the societal harm associated with these substances. In trafficking cases involving heroin or cocaine, courts routinely impose sentences at the upper end of the statutory range, citing both the potency of the drug and its association with organized crime (Yargıtay 10. Ceza Dairesi, E. 2016/2855, K. 2016/7429). This substance-based aggravation reflects a policy choice that prioritizes harm reduction and deterrence over strict proportionality based solely on quantity. Compared to systems that rely heavily on weight thresholds, Turkish law places greater emphasis on qualitative harm assessment.

4.4. Use or Exploitation of Minors

Involving minors in drug-related activities constitutes a particularly serious aggravating circumstance. This includes not only direct use of minors in trafficking or distribution but also indirect exploitation, such as using minors as intermediaries, lookouts or storage facilitators. Turkish courts treat this aggravation as an expression of heightened moral blameworthiness. Sentences are significantly increased, and mitigating factors are applied restrictively. Even where the minor’s role appears limited, courts emphasize the long-term social harm associated with exposing minors to narcotic crime. Comparatively, this approach mirrors international child-protection standards and reflects a convergence between criminal law and human rights considerations.

4.5. Commission of the Offence by Abuse of Official Position or Special Trust

Although not exclusive to narcotic offences, abuse of official position operates as an aggravating factor where public officials exploit their authority to facilitate drug-related crimes. This includes customs officers, law enforcement personnel or regulatory officials who misuse their powers to enable trafficking or concealment. Judicial practice demonstrates a particularly strict stance in such cases. Courts view abuse of public trust as compounding the societal harm caused by narcotic offences, often imposing maximum penalties and rejecting mitigation requests.

4.6. Cumulative Application and Sentencing Impact

A defining feature of Turkish narcotics law is the cumulative application of aggravating circumstances. Multiple aggravations may be applied simultaneously, resulting in substantial sentence enhancements. In practice, this can transform a base offence into a de facto life-altering sanction, particularly in cases involving organized crime, protected zones and high-risk substances. Yargıtay jurisprudence emphasizes that aggravating factors must be individually justified and supported by factual findings. However, once established, courts display limited discretion to moderate their cumulative effect, reflecting the legislature’s strong deterrent orientation (Yargıtay 20. Ceza Dairesi, E. 2017/6864, K. 2017/6864).

5. Criminal Procedure and Enforcement Practices

Narcotic drug offences in Turkey are not only defined by severe substantive penalties; they are also characterised by an enforcement culture and procedural approach that tends to prioritise early intervention, broad investigative powers and strict pre-trial measures. In practice, the outcome of a drug case often turns less on abstract legal definitions and more on how the investigation is initiated, how evidence is gathered and preserved, and how courts interpret intent and scale at the charging and trial stages. For foreign nationals and corporate actors, procedural risks can be amplified by language barriers, unfamiliarity with Turkish criminal procedure and the practical realities of detention and forensic processes.

5.1. Competent Authorities and Operational Structure

Drug investigations are typically conducted by specialised anti-narcotics units of the Turkish National Police in urban jurisdictions and by the Gendarmerie in rural areas. The Coast Guard and Customs Enforcement play a decisive role in maritime routes, ports and border zones, while intelligence-led coordination may involve multiple agencies in large-scale operations. Although operational practices vary by region, a consistent feature is the reliance on proactive methods -surveillance, informant intelligence and coordinated raids – rather than purely complaint-driven enforcement.

In international or cross-border cases, Turkish authorities frequently coordinate through INTERPOL channels, bilateral law-enforcement cooperation and mutual legal assistance requests, particularly where suspects are subject to Red Notices or where trafficking routes are linked to multiple jurisdictions. These cooperative mechanisms tend to affect timing and evidence collection, especially regarding digital records, financial trails and communications data.

5.2. Opening of the Investigation and Evidentiary Thresholds

Under Turkish criminal procedure, investigations are generally initiated by the public prosecutor (Cumhuriyet savcısı), who directs the investigative phase and authorises key measures through judicial mechanisms where required. In drug cases, investigations may begin through a wide range of triggers: intelligence reports, surveillance findings, border seizures, controlled deliveries, anonymous tips or the discovery of suspicious substances during unrelated stops.

At this early stage, the evidentiary threshold is not “proof beyond reasonable doubt,” but the presence of reasonable suspicion sufficient to justify investigative steps. However, because narcotic offences are treated as high-risk crimes, there is often a practical tendency to escalate investigative measures swiftly once a suspicion of trafficking is formed, even if initial evidence is limited. This is one reason why early legal representation matters: first-stage procedural decisions – search authorisations, seizure protocols, initial statements – requently shape the case’s trajectory.

5.3. Search, Seizure and Forensic Chain of Custody

Search and seizure are central to Turkish narcotics prosecutions. Searches may be conducted in homes, vehicles, workplaces and digital environments. The legal sustainability of a drug case frequently depends on whether the search was lawfully authorised and properly documented, whether the seizure was correctly recorded, and whether the chain of custody for seized substances was preserved. In contested cases, defence strategy often focuses on procedural legality and evidence integrity. Where the physical substance is not properly seized, or where the chain of custody is vulnerable, courts may be compelled to reassess the reliability of the prosecution narrative. This is particularly important in personal-use cases, where Yargıtay has indicated that technical evidence – seized material, toxicology, or objective corroboration – is essential and that convictions cannot rest solely on uncorroborated statements (Yargıtay 10. Ceza Dairesi, E. 2018/5513, K. 2018/9413).

Forensic analysis typically includes identification of the substance, purity, net weight, and in some cases the presence of fingerprints or trace evidence on packaging. The forensic reports become a primary anchor for both charging and sentencing, especially where the prosecution alleges trafficking rather than personal use. In practice, disputes may arise over sampling methods, measurement accuracy, and whether the substance examined corresponds to what was originally seized.

5.4. Arrest, Detention and the Pre-Trial Phase

Drug investigations in Turkey frequently involve immediate detention measures, particularly where trafficking is suspected. After an arrest, suspects are generally brought before the prosecutor for an initial statement and then, where detention is sought, before a criminal judgeship of peace (sulh ceza hâkimliği) to decide on pre-trial detention or alternative measures.

Pre-trial detention is common in serious drug cases and is often justified by reference to flight risk, risk of evidence tampering, or the seriousness of the offence. In practice, the alleged classification of the offence – trafficking under Article 188 versus possession for use under Article 191 – can be decisive at this stage. Courts may treat trafficking allegations as inherently high-risk and therefore detention-prone, even where the defence disputes the classification.

For foreign nationals, detention risks can increase due to perceived flight risk and lack of stable residence ties. Moreover, language barriers and limited access to immediate legal counsel can make the first 24–48 hours procedurally decisive. Ensuring interpreter support and protecting the right to silence and legal consultation is critical in preventing self-incriminating statements that later become the case’s backbone.

5.5. Charging Decisions: Use vs. Trafficking as the Central Fault Line

One of the most important procedural and substantive junctions is the prosecutorial decision on whether the facts support a charge under Article 188 (trafficking-related offences) or Article 191 (personal use). Turkish practice does not rely solely on the quantity of drugs. Courts and prosecutors are expected to consider contextual indicators – packaging style, presence of scales, cash, communications evidence, prior conduct and witness testimony – when determining intent (Yargıtay 20. Ceza Dairesi, E. 2017/6864, K. 2017/6864). This doctrinal stance has major procedural consequences. A trafficking charge may lead to heavier detention measures, more aggressive evidentiary interpretation, and higher sentencing exposure, while a personal-use classification may open the door to probation and treatment mechanisms. Accordingly, one of the most consequential phases of a drug case is often the early stage, when the narrative of intent is formed from limited evidence.

5.6. Trial Process and Judicial Evaluation of Evidence

At trial, Turkish courts evaluate drug cases through a combination of documentary evidence (forensic reports, seizure records, surveillance logs, digital data), witness statements and, where available, confessions. The evidentiary approach tends to be fact-intensive and contextual, particularly in borderline cases where the line between use and trafficking is contested. Yargıtay jurisprudence underscores that courts must reason explicitly about why the facts support trafficking rather than use, and that conclusions cannot be based solely on general assumptions or stereotyped inferences. For instance, courts must analyse not only quantity, but also packaging and behavioural indicators (Yargıtay 20. Ceza Dairesi, E. 2017/6864, K. 2017/6864). Similarly, where a conviction depends heavily on a confession, courts must assess corroboration through technical evidence (Yargıtay 10. Ceza Dairesi, E. 2018/5513, K. 2018/9413).

Where aggravating circumstances are alleged – proximity to protected locations, involvement of minors, organized crime structures – courts are expected to make separate factual findings supporting each aggravation, because these factors can drastically increase the sentence. In practice, however, once trafficking is established, aggravations may be applied strictly, and appellate review often focuses on whether the factual findings were sufficiently reasoned and supported.

5.7. Sentencing Practice and Post-Conviction Consequences

Sentencing in narcotics cases is heavily influenced by the statutory ranges and aggravating factors discussed earlier. Courts tend to impose stern penalties in cases involving trafficking, organized crime or high-risk substances. In personal-use cases, courts may favour rehabilitative measures, but only where the evidentiary profile supports a genuine use-related classification and where the accused cooperates with supervisory requirements. For foreign nationals, convictions may trigger deportation proceedings and entry bans following completion of sentence or release. Even absent a conviction, prolonged pre-trial detention and pending trial restrictions can have severe personal and professional consequences. For corporate actors, parallel administrative proceedings – license suspensions, audits, regulatory penalties – may proceed alongside criminal investigation, and reputational damage can become immediate even before a final judgment.

6. Yargıtay (Court of Cassation) Case Law and Judicial Interpretation

In Turkish narcotics litigation, statutory provisions alone rarely determine outcomes. The decisive fault lines – use versus trafficking, evidentiary sufficiency, the meaning of “intent,” the operation of aggravating factors, and the treatment of procedural irregularities – are largely shaped by Yargıtay (the Court of Cassation). For practitioners, Yargıtay case law functions as a practical guide that standardises lower-court reasoning, sets minimum evidentiary thresholds and limits discretionary shortcuts in drug cases. This section systematises the key interpretive themes and demonstrates how leading decisions resolve recurring problems and reshape everyday practice.

6.1. Evidence Requirements in Personal Use Cases

A recurrent issue in Article 191 prosecutions is whether a conviction can be sustained where no narcotic substance is seized and the file relies primarily on statements. Yargıtay has adopted a cautious approach that insists on objective corroboration. The Court’s reasoning is grounded in a fundamental procedural principle: criminal liability, even for low-level use offences, must rest on reliable evidence capable of verification, not solely on an uncorroborated confession or hearsay. The decision of Yargıtay 10. Ceza Dairesi, E. 2018/5513, K. 2018/9413 (17.12.2018) is frequently cited as a benchmark in this regard. The Court emphasised that for a conviction under Article 191, there must be sufficient technical evidence such as toxicology findings or seized material, and it reversed a conviction that had relied only on the defendant’s statement without material corroboration (Yargıtay 10. Ceza Dairesi, E. 2018/5513, K. 2018/9413). The problem the decision resolves is straightforward but critical: it prevents Article 191 from becoming a “statement-based offence” vulnerable to coercion, misunderstanding or evidentiary inflation. Its practical impact is substantial. Prosecutors and trial courts are effectively compelled to secure and present objective evidence – laboratory reports, seizure records, or at least medically documented toxicology – before sustaining a conviction for use or possession for use. This evidentiary requirement has a secondary but equally important effect: it elevates defence strategies that focus on procedural integrity and chain of custody. If the prosecution cannot show a reliable technical link between the accused and the substance, the classification of the case as an Article 191 offence becomes legally fragile, regardless of narrative plausibility.

6.2. Use Versus Trafficking: Quantity Is Relevant but Not Determinative

The most litigated interpretive question in Turkish drug cases is the boundary between Article 188 (trafficking) and Article 191 (use). In practice, this classification shapes everything: detention decisions, charging posture, eligibility for treatment/probation, and sentencing exposure. Yargıtay’s consistent message is that courts must not reduce the analysis to a simplistic “quantity equals trafficking” approach. While drug quantity is important, it is only one variable within a broader contextual assessment. Yargıtay 20. Ceza Dairesi, E. 2017/6864, K. 2017/6864 provides a clear doctrinal statement on this point. The Court held that determination of whether possession is for personal use or trafficking must take into account not only quantity but also packaging method, the suspect’s conduct, prior behaviour and other circumstantial indicators, and it stressed that the mere presence of a “large quantity” is not, on its own, definitive proof of trafficking (Yargıtay 20. Ceza Dairesi, E. 2017/6864, K. 2017/6864). The problem this decision resolves is an evidentiary shortcut that had become common in some lower courts: classifying borderline cases as trafficking purely on weight. The practical impact is a structured checklist approach. Courts are expected to examine whether the substance is portioned into sale-ready units, whether there is evidence of repeated transactions, whether communication data indicates commercial contact, and whether tools associated with distribution are present. This doctrinal stance also changes the strategic posture of both prosecution and defence. Prosecutors must build an “intent narrative” supported by objective indicators rather than relying on quantity alone. Defence counsel, conversely, can target the absence of sale-related markers to argue for reclassification under Article 191 and access to rehabilitative measures.

6.3. Aggravated Trafficking: High-Risk Substances and Concealment Methods as Sentencing Multipliers

Where trafficking is established, Yargıtay jurisprudence becomes particularly consequential in how aggravating factors are applied. One leading pattern in case law is the Court’s willingness to treat concealment sophistication and high-risk substances as indicators of aggravated trafficking deserving upper-range sentencing. Yargıtay 10. Ceza Dairesi, E. 2016/2855, K. 2016/7429 is illustrative. In that case, the Court upheld a conviction under Article 188 where the accused was found with over 10 kilograms of heroin concealed in a vehicle. The reasoning highlighted both the drug type (heroin) and the organised concealment method as factors supporting harsher sentencing and aggravated classification (Yargıtay 10. Ceza Dairesi, E. 2016/2855, K. 2016/7429). The problem the decision resolves concerns the evidentiary and normative link between concealment sophistication and culpability. The Court effectively signals that professional concealment methods are not neutral logistics but an indicium of organised trafficking and heightened intent. The practical effect is that vehicle concealment, false compartments and coordinated transport planning frequently lead courts to treat cases as aggravated trafficking, even before explicit organised crime findings are litigated. In practice, this line of reasoning interacts with the broader enforcement culture: sophisticated concealment tends to justify both detention decisions and prosecutorial resistance to reclassification claims. It also affects the evidentiary weight of forensic findings, because concealment often correlates with larger quantities and higher purity levels.

6.4. Protected Zones and “Strict Liability by Geography”: The 200-Meter Rule

Another recurring interpretive theme is the aggravation based on proximity to sensitive locations such as schools. Turkish law treats such proximity as an aggravating circumstance, and Yargıtay has endorsed an objective application that does not require proof of intent to target minors. Yargıtay 10. Ceza Dairesi, E. 2013/12973, K. 2015/1472 upheld enhanced sentencing for drug sale committed within 200 meters of a school, emphasising that the spatial factor alone triggers the aggravating clause even if the offender did not specifically intend to sell to minors (Yargıtay 10. Ceza Dairesi, E. 2013/12973, K. 2015/1472). The problem this decision resolves is inconsistency in lower-court reasoning where some courts demanded proof of targeting vulnerable groups. Yargıtay’s approach standardises the rule as geography-based. Its practical impact is twofold. First, prosecutors often focus early on establishing the distance element through official measurements and maps. Second, defence strategies shift toward challenging the measurement methodology, the precise location of the act, and whether the legally relevant point is the sale location, the storage location, or the point of apprehension. This jurisprudence effectively creates a “strict liability by geography” in sentencing enhancement, making spatial evidence and measurement procedures central to case outcomes.

6.5. How Yargıtay’s Case Law Reshapes Daily Practice: Three Operational Consequences

First, Yargıtay decisions impose minimum standards of proof that influence investigative behaviour. The insistence on technical evidence in Article 191 cases encourages prosecutors and law-enforcement units to prioritise seizure integrity, forensic reporting and toxicology processes, and it raises the litigation cost of files built on statements alone (Yargıtay 10. Ceza Dairesi, E. 2018/5513, K. 2018/9413). 

Second, Yargıtay’s contextual approach to intent creates a structured analytical model that discourages simplistic classification. In use-versus-trafficking disputes, courts increasingly reason through a set of indicators – packaging, tools, communications, behaviour – rather than a single quantitative metric (Yargıtay 20. Ceza Dairesi, E. 2017/6864, K. 2017/6864). This improves legal predictability but also increases the importance of early defence intervention, because many of these indicators are shaped by how the initial search, seizure and reporting are conducted.

Third, case law on aggravations turns certain factual details into decisive sentencing drivers. The 200-meter rule makes measurement evidence critical (Yargıtay 10. Ceza Dairesi, E. 2013/12973, K. 2015/1472), while concealment sophistication and drug type can elevate a case into aggravated trafficking with upper-range penalties (Yargıtay 10. Ceza Dairesi, E. 2016/2855, K. 2016/7429). As a result, narcotics litigation often hinges on a small number of “high-leverage facts,” and the way they are documented becomes outcome-determinative.

7. Legal Implications for Foreign Nationals

Foreign nationals are frequently drawn into Turkish narcotics proceedings not because Turkish law treats them differently, but because the combination of strict substantive rules, detention-oriented practice in trafficking cases, and procedural vulnerabilities can produce disproportionately severe consequences. Turkish narcotics legislation applies uniformly to citizens and non-citizens, yet foreign nationals often face additional practical risks: communication barriers, limited understanding of local classifications, weaker community ties in detention assessments, and immigration consequences that may outlast the criminal process itself. In many cases, the most damaging outcome is not only the prison sentence but the long-term removal and re-entry restrictions that follow.

7.1. Equal Application of Substantive Criminal Law, Unequal Practical Exposure

As a matter of black-letter law, a foreign national is prosecuted under the same provisions as a Turkish citizen for production, import/export, trafficking, facilitation, or personal use offences (TPC Articles 188-192). There is no separate, lighter “foreigner regime”. This is particularly significant because conduct perceived as low-level or even permissible in other jurisdictions – such as possession of cannabis for personal use, carrying khat, or transporting certain controlled pharmaceuticals without documentation – may fall squarely within Turkish criminal provisions and trigger immediate arrest.

The most common legal misunderstanding concerns classification. In everyday practice, foreign nationals often underestimate how Turkish law differentiates between possession for personal use (TPC Article 191) and trafficking/supply offences (TPC Article 188). The classification is not based only on the quantity seized. Packaging, communications, possession of distribution tools, and surrounding circumstances may push a file toward Article 188 even where the accused insists the substance was for personal use (Yargıtay 20. Ceza Dairesi, E. 2017/6864, K. 2017/6864). This doctrinal approach affects foreign nationals acutely because they may carry substances in forms or quantities that appear normal to them but are interpreted as “sale-ready” indicators under Turkish judicial practice.

7.2. Investigation-Stage Risks: Statements, Interpretation, and Early Narrative Lock-In

For foreign nationals, the investigation stage often determines the final outcome. Initial statements given during police custody, sometimes without effective interpretation or without fully understanding the legal significance of words used, can lock the case into a prosecution narrative that is difficult to reverse later. Even where a foreign national’s intent is contested, early statements may be treated as implicit admissions regarding acquisition, purpose, or knowledge.

This risk is compounded by language and cultural factors. A suspect may not understand the nuanced difference between “I had it,” “I carried it,” and “it was in my bag,” or may attempt to cooperate by speaking freely, not realising that these statements can be later framed as evidence of knowledge and control. Although the right to remain silent and to consult counsel is available, in practice foreign nationals may not exercise these rights effectively without immediate legal support and qualified interpretation.

In addition, evidentiary vulnerability is not always a protection unless it is actively raised. Yargıtay case law indicates that even in personal use files, technical evidence is required and convictions cannot rest solely on uncorroborated statements (Yargıtay 10. Ceza Dairesi, E. 2018/5513, K. 2018/9413). Yet foreign nationals may not be aware that the absence of seizure integrity, chain-of-custody issues, or lack of toxicology can provide a meaningful defence line. Without timely counsel, these issues may remain unchallenged and effectively waived at the practical level.

7.3. Pre-Trial Detention and Judicial Assessment of Flight Risk

One of the most immediate and consequential risks for foreign nationals is pre-trial detention. In serious narcotics allegations, detention is common. For foreigners, the perceived flight risk is often higher due to absence of permanent residence, family ties, stable employment documentation in Turkey, or a long-term legal status. Even where the evidence is contestable, courts may prefer detention measures, reasoning that international mobility and uncertain ties increase the risk of absconding. This becomes particularly decisive where the prosecution alleges trafficking under Article 188 rather than personal use under Article 191. Because Article 188 offences carry very high penalties, courts frequently view detention as proportionate and necessary. In practical terms, a foreign national’s case may become structurally harder once detention is ordered: communication with counsel is more difficult, evidence collection is constrained, and the psychological pressure to accept narrative compromises increases.

7.4. Trial-Stage Risks: Technical Evidence, Classification Disputes, and Sentencing Severity

At trial, the core issues for foreign nationals often mirror those for Turkish citizens, but the stakes can be higher due to downstream immigration consequences. Courts evaluate intent, quantity, packaging, and contextual indicators, and may draw adverse inferences from travel patterns or cross-border movement, particularly where the case involves airports, hotels, shipping, or transit routes. Foreign nationals may also experience disproportionate exposure to aggravating findings. For example, if the offence is alleged to have occurred near protected zones, the 200-meter aggravation can be applied objectively without proof of intent to target minors (Yargıtay 10. Ceza Dairesi, E. 2013/12973, K. 2015/1472). Likewise, if concealment methods are considered sophisticated, courts may treat the case as aggravated trafficking and impose upper-range sentences (Yargıtay 10. Ceza Dairesi, E. 2016/2855, K. 2016/7429). In practice, a foreign national may be less able to contest measurement methodology, forensic assumptions, or investigative shortcuts without specialised counsel.

7.5. Immigration Consequences: Deportation and Entry Bans as “Second Punishment”

For foreign nationals, narcotics allegations typically trigger an immigration dimension that can operate as a form of second punishment. Depending on the individual’s status and the nature of the case, immigration authorities may initiate removal procedures during or after the criminal process. Following conviction, deportation is a common outcome, and entry bans may be imposed for extended periods. Even where a sentence is served, the person may be removed immediately upon release, effectively preventing any reintegration or continuation of life in Turkey. Critically, immigration consequences may also arise without a final conviction in some situations, particularly where the authorities assess the person as a public order risk. While the legal thresholds and procedural safeguards differ from criminal proceedings, the practical reality is that foreign nationals can face loss of residency, inability to return, and long-term disruption to family and business life. This dimension is particularly relevant for expatriates, foreign employees and business owners operating in Turkey, because criminal proceedings may also trigger regulatory or employment consequences, contractual termination and reputational damage, even before a judgment becomes final.

7.6. Practical Risk-Reduction Guidance for Foreign Nationals

Foreign nationals should treat any narcotics-related contact with law enforcement in Turkey as legally high-stakes. The most effective risk-reduction strategy is early legal intervention. Immediate steps should focus on ensuring effective interpretation, protecting procedural rights, and preventing the early narrative from being fixed in a manner inconsistent with the facts. From a practical standpoint, foreign nationals should avoid making substantive statements before consulting counsel, should insist on qualified interpretation, and should ensure that all procedural documents – search records, seizure minutes, forensic sampling reports – are reviewed for legality and completeness. In borderline cases, the legal strategy often hinges on classification: re-framing the file under Article 191 rather than Article 188 can transform both the procedural pathway (detention vs. probation) and the ultimate outcome (treatment/deferred prosecution vs. long imprisonment).

Equally important is preventive compliance. Visitors and residents should not assume that home-country legality translates into Turkish legality. Prescription medications should be carried with proper documentation. Controlled substances should never be transported for third parties, even casually, because possession and control in Turkish law can rapidly be interpreted as knowledge and intent. Finally, foreign nationals involved in regulated industries – pharmaceuticals, healthcare, chemicals and logistics – should seek compliance guidance because corporate handling errors can quickly escalate into criminal exposure for individuals.

8. Corporate and Regulatory Liability for Controlled Substances

In Turkey, narcotics regulation is not confined to classic criminal prosecution of individuals. A parallel and highly consequential compliance regime governs the lawful handling of narcotic and psychotropic substances in the pharmaceutical, healthcare, chemical, logistics and manufacturing sectors. Corporate exposure arises not only from intentional diversion into illicit markets but also from regulatory non-compliance, weak internal controls, recordkeeping failures and security vulnerabilities. In practice, the line between administrative irregularity and criminal suspicion can be thin. Once authorities suspect diversion or deliberate misuse, regulatory breaches may be reinterpreted as indicia of criminal intent, and corporate files may rapidly escalate into criminal investigations targeting both the company and responsible individuals.

8.1. Regulatory Architecture: Who Regulates and Why It Matters

Controlled substances that are lawfully used for medical and scientific purposes are subject to an authorization-based regime administered primarily through the Ministry of Health and associated regulatory bodies. The regulatory system is designed to implement Turkey’s international obligations under the principal drug control conventions and to prevent diversion from legitimate supply chains into illegal distribution channels. This objective creates a compliance environment in which formal authorizations are not treated as procedural paperwork but as a core condition of legality.

For companies, this means that the legal status of a controlled substance is not determined simply by its commercial availability, but by whether each step of the supply chain – procurement, import, storage, production, transfer, and disposal – occurs within an approved and traceable framework. The absence of one authorization, or a deviation from approved procedures, may be treated as a compliance failure at the administrative level, but it can also serve as the trigger for criminal scrutiny if the facts suggest diversion or concealment.

8.2. Licensing as a Condition of Legality

Licensing and authorizations are the first and most fundamental compliance pillar. Companies dealing with controlled substances must typically obtain permits for each distinct activity: production/manufacturing, import and export, wholesale distribution, storage, and in some cases internal transfer between facilities. Licensing requirements are not static. They may be substance-specific, activity-specific, and time-limited, and they often require regular renewal and periodic reporting.

From a liability perspective, licensing failures can operate in two ways. First, operating without a required license, or exceeding its scope, may constitute a regulatory breach leading to administrative sanctions, including suspension of operations and significant fines. Second, and more dangerously, unauthorized handling of controlled substances can become the factual basis for criminal allegations when authorities argue that the conduct is no longer within the lawful regulatory sphere and therefore falls into the domain of criminal illegality under the Turkish Penal Code.

The risk is particularly acute in borderline situations, such as importing controlled substances under incomplete documentation, storing quantities inconsistent with declared use, or transferring substances between facilities without the correct permits. Even if these acts arise from internal mismanagement rather than criminal intent, they can generate suspicion and trigger a criminal process that is difficult to contain once initiated.

8.3. Inspections, Audits and Enforcement Dynamics

The compliance regime is reinforced through inspections and audits. Regulatory authorities may conduct scheduled or unannounced inspections focusing on inventory reconciliation, storage security, access logs, distribution records and reporting accuracy. In sectors such as pharmaceuticals and healthcare, inspection findings frequently serve as the starting point for a broader enforcement process.

A critical feature of Turkish practice is the escalation mechanism. An administrative inspection may begin as a regulatory compliance check but may be escalated into criminal referral if inspectors identify anomalies suggestive of diversion or falsification. Discrepancies between physical inventory and records, unexplained losses, irregularities in shipment documentation, or repeated procedural breaches can be interpreted as red flags. Once such indicators exist, prosecutors may view the file not merely as a compliance matter but as potential facilitation of trafficking or unlawful supply.

In this sense, inspections are not a separate administrative domain; they are a gateway into criminal enforcement where the factual profile supports suspicion. For corporate actors, the practical lesson is that regulatory compliance is a form of criminal risk management.

8.4. Recordkeeping and Traceability as the Core Compliance Duty

In controlled substances regulation, recordkeeping is not ancillary; it is the backbone of legality. Companies are expected to maintain detailed records of procurement sources, production volumes, inventory levels, storage conditions, transfers and final distribution. Reporting obligations may extend to periodic submission of inventory reports and transaction summaries, and the failure to report accurately can be treated as a serious breach.

In criminal investigations, recordkeeping failures can have a structural effect. When traceability is weak, the company loses the ability to demonstrate lawful origin, lawful purpose and lawful movement of substances. This weakens any defence narrative and can enable prosecutors to infer intentional concealment. The corporate file then becomes vulnerable not only to administrative penalties but to criminal accusations framed as unauthorized handling or facilitation.

This is where the intersection between administrative compliance and criminal liability becomes most visible. A recordkeeping error might appear, in isolation, to be a technical omission. Yet within a strict regulatory environment, repeated or systemic record failures can be treated as evidence of knowledge and intent. If the prosecution narrative shifts in this direction, the file may move from administrative to criminal terrain.

8.5. Security, Diversion Prevention, and the “Corporate Duty of Control”

Controlled substances are high-value and high-risk items, and Turkish regulatory expectations place significant emphasis on security measures. Companies are expected to implement physical security systems, access controls, personnel vetting, and diversion prevention protocols. In practical terms, the “security duty” is a corporate duty of control: the company must actively prevent theft, leakage and diversion, rather than merely react after loss occurs.

Where diversion is suspected, security vulnerabilities may be interpreted as negligence at the administrative level or as complicity at the criminal level depending on evidence. If diversion occurs through insider theft or collusion, investigators may examine whether the company’s systems were genuinely capable of preventing it, whether management ignored warning signs, and whether internal audits were effective.

In serious cases, weak security is not treated as a neutral failure but as a risk factor that increases suspicion of deliberate facilitation. This is particularly relevant for logistics operators and warehouses, where controlled substances may be stored temporarily and where chain-of-custody vulnerabilities can become the central factual issue.

8.6. Individual Liability of Directors, Managers and Employees

Although corporate compliance is the first layer, Turkish enforcement frequently targets individuals. Criminal responsibility attaches to natural persons who directly engage in unlawful conduct or who participate in it through management decisions, oversight failures, or deliberate toleration of irregular practices.

For directors and senior managers, liability risk often arises through the concept of “effective control”. If a manager has decision-making authority over procurement, storage, distribution or compliance systems, investigators may argue that irregularities could not have occurred without managerial knowledge or culpable neglect. For employees, liability may arise where staff directly handle substances, manipulate records, facilitate unauthorized transfers, or engage in insider theft.

From a compliance strategy perspective, training and internal oversight are therefore not merely best practices but legal risk shields. Where a company can document robust training, periodic audits, and effective supervision, it is better positioned to argue that a violation was individual misconduct rather than corporate facilitation. Conversely, absence of training and lax oversight can be framed as “organizational enabling conditions,” increasing both administrative sanction risk and criminal exposure.

8.7. The Administrative – Criminal Intersection: How Files Escalate

The most important practical reality for companies is that administrative enforcement and criminal enforcement are not separate universes. A typical escalation pathway begins with an inspection finding – inventory discrepancy, missing records, unreported transfers – followed by administrative action and, if suspicion persists, referral to prosecutors. Once prosecutors become involved, the evidentiary focus shifts. Instead of asking “Was the regulation violated?” the question becomes “Does the violation indicate unauthorized handling, diversion, or facilitation of trafficking?”

This shift changes the stakes dramatically. Administrative sanctions may include fines and license restrictions, but criminal proceedings can involve arrests, search warrants, seizure of company records, and prosecution under the Turkish Penal Code provisions governing trafficking or facilitation (TPC Article 188; TPC Article 190). The reputational impact is often immediate, and business continuity may be threatened even before any conviction.

In corporate narcotics files, one of the most sensitive points is intent. Where the facts can be framed as a compliance failure without criminal purpose, early legal intervention focuses on reconstructing records, demonstrating lawful purpose, cooperating with regulatory remediation and preventing the narrative from crystallizing into criminal intent. Where the facts suggest deliberate diversion, the defence strategy shifts toward procedural legality, evidentiary challenges and individualization of responsibility.

8.8. Practical Compliance Guidance for Corporate Actors

The most effective corporate defence is preventive. Companies operating in controlled-substance sectors should treat narcotics compliance as a board-level risk. Licensing matrices should be maintained and updated. Inventory reconciliation should be regular and independently audited. Access to controlled substances should be limited, logged and monitored. Training should be documented and refreshed. Incident response protocols should exist for losses, suspected diversion or inspection events. For multinational companies and foreign investors, compliance programs must also account for cross-border documentation, import/export authorizations and internal transfer controls, because deficiencies in cross-border paperwork are among the most common triggers for enforcement escalation.

9. International Drug Operations Involving Turkey

Turkey’s position between production zones and consumer markets means that a significant portion of high-impact narcotics enforcement is no longer purely domestic. Large files frequently involve suspects, proceeds, communications and logistics that span multiple jurisdictions. As a result, “international operations involving Turkey” should be understood not only as police actions on Turkish soil, but as multi-layered legal processes that combine INTERPOL mechanisms, extradition, mutual legal assistance (MLA), joint investigative work, and asset-tracing measures. In practice, the operational headline – an arrest, a seizure, a raid – often represents the final step of a longer legal chain built through cooperation requests and cross-border evidence exchange.

9.1. INTERPOL Red Notices: What They Are and What They Are Not

INTERPOL Red Notices are among the most visible tools in transnational narcotics enforcement, but they are also among the most frequently misunderstood. A Red Notice is not, by itself, an “international arrest warrant”. It is a request circulated through INTERPOL channels asking member countries to locate and provisionally arrest a person pending extradition, subject to each state’s domestic law and judicial control (INTERPOL Constitution; INTERPOL Rules on the Processing of Data). In Turkish practice, the existence of a Red Notice can trigger identification, surveillance, and detention measures, but the legal basis and limits of deprivation of liberty remain grounded in Turkish law and judicial review.

From a defence and compliance perspective, the practical significance of a Red Notice is that it shifts risk from “border control” to “any point of contact” with state systems – hotel registration, traffic controls, identity checks, or administrative procedures. For fugitives alleged to be connected to narcotics networks, Turkey has increasingly been a venue where Red Notice subjects are located and detained, partly because of travel patterns, transit logistics and the use of Türkiye-based hubs.

9.2. Extradition: The Legal Route from Arrest to Transfer

Extradition is the primary lawful pathway for transferring a foreign suspect from Turkey to another jurisdiction for prosecution or sentence enforcement. In Turkish law, extradition operates under a combination of treaty obligations and domestic legislation, most centrally Law No. 6706 on International Judicial Cooperation in Criminal Matters (Law No. 6706). Turkey’s treaty framework includes bilateral agreements and, where applicable, multilateral instruments such as the European Convention on Extradition (1957) for Council of Europe relationships (European Convention on Extradition, 1957).

Narcotics offences are typically extraditable because they meet the “dual criminality” requirement in most legal systems: the alleged conduct is criminal in both states. However, extradition is never purely automatic. Turkish courts and authorities evaluate procedural conditions and refusal grounds that may include the risk of political prosecution, the principle of speciality, potential human rights concerns, and the general legality of the requesting state’s process (Law No. 6706). This becomes particularly sensitive in high-profile files, where defendants argue that “drug charges” are being used as a proxy for political objectives. Turkish practice requires careful differentiation between genuine transnational narcotics enforcement and requests that carry political character, as extradition decisions can become diplomatically and legally contested.

A recurring operational pattern in narcotics cases is that the arrest is made in Turkey, but prosecution is pursued elsewhere where the alleged network’s operational centre, financial flows, or evidentiary base is stronger. In such files, Turkey’s role is that of arrest-and-surrender jurisdiction, and the legal quality of the extradition process – proper documentation, sufficient evidentiary basis, and respect for judicial safeguards – becomes determinative.

9.3. Mutual Legal Assistance: Evidence is the Real Currency of Cooperation

While extradition concerns persons, mutual legal assistance concerns evidence. Drug-trafficking cases increasingly depend on digital data, financial records, travel histories, communications metadata, and cross-border surveillance outputs. The legal vehicle for such evidence exchange is mutual legal assistance, implemented through treaties and domestic provisions under Law No. 6706 (Law No. 6706; 1988 Vienna Convention, Art. 7 and Art. 9; UN Convention against Transnational Organized Crime, Art. 18).

MLA requests commonly seek search and seizure assistance, bank records, subscriber information, witness statements, forensic material, and authenticated court documents. For Turkish prosecutors, MLA is particularly crucial when attempting to prove “intent to traffic” rather than mere possession, because intent is often inferred from communications, repeated transactions, and financial flows that sit outside Turkey.

For defence, the MLA layer raises two high-stakes questions. The first is admissibility: whether the evidence was obtained in a manner consistent with Turkish procedural safeguards and whether chain-of-custody integrity is maintained when evidence crosses borders. The second is contextual fairness: whether translated, summarized, or intelligence-derived foreign materials are being used as proof without sufficient judicial testing. In large trafficking files, these evidentiary disputes can become outcome-determinative.

9.4. Joint Investigations and Operational Coordination

Modern narcotics enforcement often operates through “coordinated operations” rather than isolated national actions. Coordination may take the form of synchronized raids, controlled deliveries, parallel financial investigations, and simultaneous arrests across multiple states. Legally, such coordination relies on a combination of MLA, police-to-police cooperation, and treaty-based frameworks encouraging coordinated action against transnational organized crime (1988 Vienna Convention; UNTOC).

Turkey’s operational agencies – police, gendarmerie, coast guard, and customs enforcement – frequently act within these frameworks, particularly where routes connect to Europe, the Balkans, the Middle East or maritime corridors. In practice, coordination is not merely a logistical matter; it influences forum choice, charging strategies, and the narrative of the case. A state may pursue prosecution because it has the strongest evidence base, the most severe statutory regime, or the greatest leverage over accomplices and assets.

9.5. Illustrative Operational Patterns: Three Common Pathways

Recent public cases and enforcement narratives involving Turkey can be grouped into recurring pathways. The first pathway is the “Red Notice capture” model: a person wanted abroad is located and detained in Turkey based on an INTERPOL notice, followed by extradition proceedings in Turkish courts. The operational headline is an arrest, but the legal core is extradition litigation under Law No. 6706 and the applicable treaty framework.

The second pathway is the “network dismantling” model: Turkey acts as a site of enforcement against internationally networked criminal organizations whose activities extend into multiple jurisdictions. These operations often involve parallel evidence collection abroad and coordinated action at multiple nodes of the network, reflecting the practical logic of transnational enforcement.

The third pathway is the “seizure and disruption” model: large-scale seizures linked to international routes are made in Turkey or en route to Turkey, with subsequent investigations expanding into cross-border cooperation requests for upstream suppliers, financiers and logistics facilitators. In such files, the seizure is the visible anchor, while MLA-driven evidence is what enables higher-level prosecutions.

9.6. Why These International Mechanisms Matter for Legal Risk Assessment

For individuals, the existence of international mechanisms means that risk is no longer confined to the country where the conduct allegedly occurred. A suspect can be arrested in Turkey for conduct primarily investigated abroad, and the legal battle may then shift to extradition litigation rather than a merits trial in Turkey. For foreign nationals and expatriates, this also means that seemingly routine travel or residence decisions can intersect with transnational enforcement architecture in unexpected ways.

For companies – particularly in logistics, shipping, and regulated chemical/pharmaceutical supply chains – the international dimension multiplies compliance expectations. A corporate compliance failure can trigger not only domestic regulatory action but also foreign investigations and cooperation requests, especially if controlled substances, precursor chemicals, or suspicious shipments appear across borders. In this environment, robust documentation, licensing discipline, and traceability are not merely regulatory best practices; they are safeguards against becoming an evidentiary node in a transnational trafficking file.

9.7. International Drug Operations Involving Turkey

Turkey’s strategic position bridging Europe and Asia has made it a focal point in international drug trafficking routes. Consequently, numerous international operations have been conducted to dismantle drug networks with ties to Turkey:​

• Capture of Comanchero Leaders (November 2023): Turkish authorities apprehended Hakan Ayik and Duax Hohepa Ngakuru, alleged leaders of the Comanchero motorcycle gang, wanted by Australian and New Zealand authorities for extensive drug trafficking and organized crime activities. The arrests were part of a broader crackdown on international criminal organizations operating within Turkey

• Extradition of Albanian Drug Kingpin (January 2025): Dritan Rexhepi, an Albanian national accused of orchestrating a global drug trafficking network, was extradited from Turkey to Albania. Rexhepi had been arrested in Istanbul in November 2023 and was implicated in coordinating cocaine shipments from South America to Europe. 

• Arrest of Swedish Cartel Leader (July 2024): Alexander G., the leader of a Sweden-based drug cartel and subject of an INTERPOL Red Notice, was captured in Istanbul during a drug raid. His arrest highlighted Turkey’s role as a refuge for international fugitives involved in narcotics trafficking.

• Seizure of Cocaine Shipments Destined for Turkey (April 2024): International law enforcement agencies have intercepted significant quantities of cocaine en route to Turkey. For instance, Turkish police seized 608 kilograms of cocaine in an operation across multiple provinces, underscoring concerns about Turkey becoming a transit hub for South American cocaine destined for Europe.

• INTERPOL Operations Targeting Turkish Networks: INTERPOL has coordinated operations targeting Turkish drug trafficking groups operating in Europe. In March 2020, European authorities arrested 13 suspected members of a Turkish drug trafficking group and seized 2.4 tonnes of heroin intended for shipment to Europe, highlighting the transnational nature of these networks. ​

These operations reflect the collaborative international efforts to combat drug trafficking networks with connections to Turkey, emphasizing the country’s pivotal role in global narcotics routes and the necessity for continued cross-border cooperation.

10. Frequently Asked Legal Questions (FAQ)

This section addresses the most common practical questions raised by individuals, foreign nationals and corporate actors in relation to narcotic drug offences in Turkey. The answers are intentionally concise, but legally grounded, and reflect both statutory provisions and settled judicial interpretation.

10.1. Can I be prosecuted in Turkey for possessing a substance that is legal in my home country?

Yes. Turkish criminal law applies territorially and does not recognise the legality of substances under foreign legal systems. Substances such as cannabis, khat or certain prescription medications may be lawful elsewhere but are strictly prohibited or regulated in Turkey. Possession, purchase or transport of such substances may lead to prosecution under the Turkish Penal Code regardless of their legal status abroad (TPC Art. 188–191; Yargıtay 20. Ceza Dairesi, E. 2017/6864, K. 2017/6864).

10.2. What is the penalty for drug trafficking in Turkey?

Drug trafficking offences under Article 188 of the Turkish Penal Code carry very severe penalties. Unauthorized production, import or export is punishable by imprisonment ranging from twenty to thirty years and substantial judicial fines. Domestic sale, supply or distribution carries penalties of ten to twenty years. Aggravating circumstances may significantly increase these ranges (TPC Art. 188; Yargıtay 10. Ceza Dairesi, E. 2016/2855, K. 2016/7429).

10.3. How do Turkish courts distinguish between personal use and trafficking?

Courts do not rely solely on the quantity of the substance. While quantity is relevant, judicial assessment focuses on contextual indicators such as packaging method, possession of distribution tools, communication records, prior conduct and surrounding circumstances. A large quantity alone is not decisive; intent is inferred from the totality of evidence (Yargıtay 20. Ceza Dairesi, E. 2017/6864, K. 2017/6864).

10.4. Is rehabilitation or probation available instead of prison?

Yes, in cases classified as possession for personal use under Article 191. First-time offenders may be offered deferred prosecution, probation and mandatory treatment programs. If the individual complies with the supervision and treatment conditions, prosecution may be suspended or dismissed. These mechanisms are generally not available in trafficking cases (TPC Art. 191; Yargıtay 10. Ceza Dairesi, E. 2018/5513, K. 2018/9413).

10.5. Can I be detained before trial for a drug offence?

Yes. Pre-trial detention is common in serious narcotics cases, particularly where trafficking under Article 188 is alleged. Courts often justify detention based on the severity of the offence, risk of flight and potential evidence tampering. For foreign nationals, perceived flight risk may increase the likelihood of detention (Code of Criminal Procedure; Yargıtay practice).

10.6. What happens if a drug offence is committed near a school or hospital?

If a drug offence is committed within the legally defined proximity to protected locations such as schools or hospitals, sentencing is aggravated. Turkish courts apply this aggravation objectively; proof of intent to target minors or vulnerable persons is not required. Spatial proximity alone suffices (TPC Art. 188/4; Yargıtay 10. Ceza Dairesi, E. 2013/12973, K. 2015/1472).

10.7. Can foreign nationals be deported after a drug case?

Yes. Conviction for a narcotic offence commonly triggers deportation proceedings and entry bans after completion of sentence. In some circumstances, immigration measures may be initiated even before a final conviction if the individual is assessed as a public order risk. Deportation operates as a separate administrative process alongside the criminal case (Law No. 6458 on Foreigners and International Protection).

10.8. Can companies be held criminally liable for narcotics violations?

While criminal liability attaches to natural persons, companies may face severe administrative sanctions, including license revocation and fines. In addition, directors, managers and employees may be individually prosecuted if they are found to have participated in or facilitated unlawful handling of controlled substances. Regulatory breaches may also serve as evidence of criminal intent in serious cases (TPC Art. 188–190; Law No. 6706; Ministry of Health regulations).

10.9. What should I do if I am arrested in Turkey on drug charges?

You should seek legal representation immediately and avoid making substantive statements before consulting a lawyer. Ensuring proper interpretation, reviewing the legality of search and seizure, and challenging classification at the earliest stage are often decisive in narcotics cases. Early legal intervention can materially affect detention decisions, charge classification and ultimate outcome (Code of Criminal Procedure; Yargıtay jurisprudence).

11. Practical Risk Assessment and Preventive Guidance

In narcotics-related matters, legal outcomes in Turkey are often shaped by a small number of “high-leverage” decisions and facts: what is said in the first hours of custody, how the search and seizure are documented, whether intent is framed as use or trafficking, whether chain-of-custody is intact, and whether compliance records exist in corporate files. For this reason, practical risk assessment should be approached as a structured exercise, not a general warning. This section sets out concrete risk scenarios for individuals, foreign nationals and companies, and then identifies preventive strategies that meaningfully reduce exposure in Turkey’s strict enforcement environment.

11.1. Individuals: Core Risk Scenarios and How Cases Escalate

The most common individual risk scenario is the “classification escalation” problem: conduct that the person perceives as low-level possession is interpreted by authorities as trafficking or supply. This escalation is rarely based on quantity alone. It often arises from contextual cues that prosecutors and courts associate with commercial intent, such as multiple packages, concealment, possession of cash in unusual forms, communications data suggesting repeated contact, or presence in environments associated with distribution. Because Turkish courts adopt a contextual approach to intent, a person’s own explanation may not control the classification if objective indicators point in another direction (Yargıtay 20. Ceza Dairesi, E. 2017/6864, K. 2017/6864).

A second risk scenario is “statement-driven liability,” particularly in personal-use files. Individuals sometimes assume that admitting use will reduce severity. In practice, an early confession can be treated as the foundation of the case narrative, especially if it is made without legal counsel or without understanding the legal consequences of specific phrasing. While Yargıtay requires technical corroboration for convictions under Article 191 and rejects purely statement-based findings (Yargıtay 10. Ceza Dairesi, E. 2018/5513, K. 2018/9413), the real-world problem is that statements influence charging posture, detention decisions and the framing of intent. Even if a conviction ultimately requires objective evidence, an early narrative can still produce severe interim consequences.

A third scenario concerns “procedural fragility masked by strong rhetoric”. Drug files often appear strong because of enforcement framing, yet they may contain chain-of-custody weaknesses, sampling irregularities, or search legality issues. These problems are not self-executing; they must be identified early, raised properly, and supported with file-based challenges. Without early defence action, procedural vulnerabilities may not be fully utilised, and the case proceeds as if the evidentiary foundation were uncontested.

Preventive strategies for individuals therefore concentrate on early-stage control. First, avoid any possession or transport of controlled substances, including “small amounts”, because Turkish law does not treat such conduct as trivial. Second, never transport items for third parties, including friends, because physical control can be interpreted as knowledge and intent, and such cases often escalate quickly into trafficking narratives. Third, if approached by law enforcement, exercise the right to legal counsel and avoid substantive statements before consultation. Fourth, if a case arises, insist on careful review of search records, seizure minutes and forensic sampling. Many decisive issues in narcotics litigation are procedural and technical rather than purely narrative.

11.2. Foreign Nationals: Amplified Risk Through Mobility and Misclassification

For foreign nationals, the same substantive rules apply, but risks are amplified by immigration consequences and detention dynamics. The most frequent foreign-national scenario is “home-country legality confusion.” Tourists and expatriates may carry substances that are legal or tolerated elsewhere – cannabis products, khat, certain sedatives or pain medications – without understanding that Turkish law treats them as prohibited or strictly controlled. This scenario is particularly severe because border or street encounters may trigger immediate arrest, and the person may not be able to explain the substance’s nature or legality in a way that resonates with Turkish classification categories.

A second foreign-national scenario is “flight-risk presumption”. Even where a case could be arguable as personal use, courts may favour detention because the individual lacks stable residence ties, has international mobility, or is perceived as able to leave Turkey quickly. Where the prosecution alleges trafficking under Article 188, detention becomes even more likely due to the high penalty range and the perceived seriousness of the offence. Once detention is imposed, the practical ability to gather defence evidence, arrange expert review of forensic reports, and challenge procedural steps becomes more constrained.

A third scenario is “translation and narrative distortion”. Statements taken under stress, through informal interpretation, or through culturally mismatched communication can create irreversible narrative damage. A foreign national might agree to a proposition without grasping its legal implications, or might use a term that authorities interpret as an admission of procurement, knowledge or intent. The procedural safeguard is the right to qualified interpretation and counsel, but the practical safeguard is to insist on these protections immediately and consistently.

Preventive guidance for foreign nationals therefore begins with pre-incident compliance discipline. Controlled prescription medications should be carried only with documentation, and substances should never be carried for others. Those residing in Turkey should understand the strictness of Turkish classifications and avoid exposure to environments associated with distribution. If a case arises, early legal representation is essential, not only for the criminal process but for managing parallel immigration consequences. Deportation and entry bans can follow conviction, and in some circumstances may be initiated as administrative measures even while criminal proceedings are pending (Law No. 6458 on Foreigners and International Protection). A comprehensive defence approach must therefore consider both criminal and immigration trajectories from the outset.

11.3. Companies: Where Compliance Failures Become Criminal Exposure

Corporate narcotics risk typically begins as a compliance issue and ends as a criminal file when authorities suspect diversion, concealment or systemic negligence. A common corporate scenario is “inventory discrepancy escalation”. During inspection or internal audit, a mismatch between physical inventory and records may be treated as an administrative breach at first, but repeated or unexplained discrepancies can trigger suspicion of diversion. Once prosecutors become involved, the same discrepancies may be framed as evidence of intentional misconduct, especially if recordkeeping is incomplete or inconsistent.

A second scenario is “cross-border documentation failure”. Import/export of controlled substances, precursor chemicals or regulated pharmaceuticals often requires layered authorizations. Missing permits, inconsistent declarations, or weak traceability can produce enforcement escalation, particularly at customs points. Even when the company’s purpose is lawful, paperwork deficiencies can be interpreted as a concealment signal. The operational reality is that border-related files escalate rapidly because they implicate trafficking narratives and because the statutory penalties for import/export offences are extremely high.

A third corporate scenario involves “employee conduct and managerial exposure”. In many cases, an insider diverts controlled substances. The legal question then becomes whether the misconduct can be individualised or whether it is attributed to organizational enabling conditions. Where training is absent, access controls are weak, oversight is lax, and audits are superficial, investigators may treat management as effectively complicit or culpably negligent. This creates direct exposure for directors and compliance officers and increases the risk of both criminal referral and administrative license sanctions.

Preventive corporate strategy therefore requires building a documentary and operational compliance posture capable of withstanding both administrative and criminal scrutiny. Licensing scope must be continuously verified. Recordkeeping must be precise, auditable and reconciled in real time. Access to controlled substances should be limited, logged and monitored. Training should be documented and refreshed, and internal audits should be independent and periodic. Crucially, companies should maintain an “incident response” protocol: if discrepancies arise, the company must be able to investigate quickly, preserve relevant records, remediate weaknesses, and present a coherent explanation grounded in documentation rather than after-the-fact narrative reconstruction.

For multinational companies, an additional preventive layer is cross-border coordination. Compliance programs must align Turkish regulatory requirements with corporate global standards and ensure that supply-chain documentation, customs declarations and internal transfers meet local legal expectations. Where foreign employees are involved, training should explicitly address Turkish classification rules and the high risks of informal handling, transport or storage practices.

11.4. A Practical Early-Response Framework When a Case Arises

Across all categories – individuals, foreigners and companies – early response is decisive. The first step is to stabilise the facts: what was seized, where, under what authorization, and how it was recorded. The second step is to protect procedural rights: ensure counsel presence, qualified interpretation, and lawful documentation of all investigative measures. The third step is to contest or confirm classification: whether the conduct is properly framed as personal use under Article 191 or as trafficking under Article 188, because this classification shapes detention, sentencing and available rehabilitative mechanisms (TPC Art. 188–191; Yargıtay 20. Ceza Dairesi, E. 2017/6864, K. 2017/6864). The fourth step is to secure technical review: forensic reports, sampling methods and chain-of-custody. Where the file involves foreign nationals or companies, parallel legal tracks – immigration measures or regulatory actions – must be managed as part of a unified strategy rather than as separate problems.

12. Legal Services and Strategic Assistance

Narcotic drug offences in Turkey generate legal exposure that is rarely confined to a single procedural moment or a single legal domain. Substantive criminal liability, procedural safeguards, regulatory compliance, immigration consequences and international cooperation mechanisms often intersect within the same file. Effective legal assistance in this area therefore requires not only familiarity with statutory provisions but also the ability to manage timing, evidence and parallel processes in a coordinated manner.

At the investigation stage, legal assistance typically focuses on protecting procedural rights and stabilising the evidentiary record. This includes reviewing the legality of search and seizure measures, assessing chain-of-custody integrity, ensuring access to qualified interpretation, and advising on the exercise of the right to silence. Early intervention is particularly important in classification disputes, where the framing of conduct as trafficking under Article 188 or possession for personal use under Article 191 can shape detention outcomes and long-term exposure. In such cases, legal analysis is inseparable from factual reconstruction: packaging, communications, forensic reports and contextual indicators must be examined together to assess whether the prosecution’s intent narrative is legally sustainable (Yargıtay 20. Ceza Dairesi, E. 2017/6864, K. 2017/6864).

During the prosecution and trial phases, legal assistance shifts toward evidentiary testing and doctrinal argumentation. This includes challenging the sufficiency and reliability of technical evidence, contesting the application of aggravating circumstances, and invoking settled Yargıtay standards on proof, intent and proportionality. In personal-use cases, attention often centres on whether the minimum evidentiary threshold has been met and whether rehabilitative mechanisms can be activated (Yargıtay 10. Ceza Dairesi, E. 2018/5513, K. 2018/9413). In trafficking cases, the focus may instead be on limiting overbroad aggravations, individualising responsibility, and preventing cumulative sentencing effects that are not adequately reasoned.

For foreign nationals, legal assistance necessarily extends beyond the criminal file. Immigration consequences such as deportation and entry bans frequently arise as parallel or subsequent processes. Coordinated legal strategy must therefore account for criminal defence, administrative immigration procedures and, where applicable, international protection or residence-status considerations. Managing these tracks together is often critical to avoiding outcomes in which procedural success in one domain is undermined by adverse action in another.

In corporate contexts, legal assistance is commonly oriented toward risk containment and escalation control. When inspections or audits reveal regulatory issues, early legal involvement aims to determine whether the matter can be contained within the administrative sphere or whether it risks criminal referral. This involves reconstructing compliance documentation, assessing licensing scope, reviewing internal controls, and advising on remedial measures. Where criminal investigations are initiated, legal analysis focuses on individualisation of liability, separation of administrative negligence from criminal intent, and protection of corporate continuity while proceedings are ongoing.

In files with an international dimension, legal assistance often requires engagement with extradition law, mutual legal assistance mechanisms and INTERPOL processes. Advising on Red Notices, provisional detention, extradition objections and evidentiary admissibility across borders is a distinct area of practice that intersects with, but is not reducible to, domestic criminal defence. Strategic coordination across jurisdictions may be necessary to ensure consistency of defence positions and to prevent adverse spillover effects from foreign proceedings.

Across all these contexts, the unifying function of legal assistance is not advocacy in the abstract, but structured risk management: identifying where legal exposure is greatest, intervening at points where procedural or evidentiary choices are still reversible, and aligning legal arguments with the realities of Turkish judicial practice rather than with purely theoretical positions.

13. Conclusion

Narcotic drug offences in Turkey are regulated through a legal framework that combines severe substantive penalties, proactive enforcement practices and a strong emphasis on deterrence. The Turkish Penal Code’s classification of offences, the cumulative operation of aggravating circumstances and the judiciary’s contextual approach to intent create a system in which outcomes are highly sensitive to early procedural decisions and evidentiary framing. Yargıtay jurisprudence has introduced important safeguards – particularly regarding proof requirements and classification standards – but these safeguards are effective only when they are actively invoked and properly grounded in the facts of each case.

For individuals, the principal risk lies in misclassification and early narrative lock-in; for foreign nationals, in the compounding effect of detention practices and immigration consequences; and for companies, in the escalation of regulatory failures into criminal investigations. In international cases, the use of extradition, mutual legal assistance and coordinated operations further complicates the legal landscape and demands careful navigation of both domestic and transnational norms.

Within this complex environment, narcotics law operates not merely as a set of prohibitions but as a multidimensional risk field where criminal, administrative and international legal regimes overlap. Meaningful legal analysis and assistance therefore require a holistic perspective – one that integrates statutory interpretation, procedural safeguards, case law standards and practical enforcement realities. It is within this integrated framework that Bıçak provides legal analysis and strategic assistance in narcotic drug-related matters, drawing on doctrinal depth and practical experience to address the full spectrum of risks arising under Turkish law.
