The Boundary Between Drug Use and Trafficking Crimes: Supreme Court Criteria (Turkish Penal Code Articles 188 and 191)

Drug Offenses under the Turkish Penal Code: Key Differences Between Possession for Personal Use (Article 191) and Trafficking (Article 188)

In the Turkish Penal Code, drug-related offenses are grouped under two main headings according to the nature and purpose of the act: the crime of drug use (Article 191 of the Turkish Penal Code) and the crime of drug trafficking (Article 188 of the Turkish Penal Code) . The legislator has assigned completely different legal consequences to the acts of an individual obtaining a substance solely for their own use and to facilitating the distribution of the substance to others.

The Crime of Possessing Narcotic Substances for Personal Use (Turkish Penal Code Article 191)

Article 191 of the Turkish Penal Code regulates the acts of purchasing, accepting, possessing, or using narcotic or stimulant substances for personal use. The fundamental approach of this article is to rehabilitate the individual rather than directly punish them. Accordingly, during the investigation phase, a case is not directly opened against the suspect; instead , a decision is made to postpone the public prosecution for a period of 5 years, and the perpetrator is subjected to a probation and treatment program lasting at least one year. If the obligations are fulfilled, the case is closed; if not, a criminal case is opened, and the suspect is tried with a request for imprisonment ranging from 2 to 5 years.

Crime of Manufacturing and Trafficking of Narcotic or Stimulant Substances (Turkish Penal Code Article 188)

Article 188 of the Turkish Penal Code covers the unlicensed manufacture, import/export, offering for sale, sale, shipment, transportation, storage, or transfer of narcotic substances to another person. The primary goal here is to introduce or distribute the substance into the market.

The separation of powers between the penal authorities and the courts— the difference between using and selling drugs —is manifested in the enormous gap in penalties between the two crimes.

• The penalty for drug trafficking , according to Article 188/3 of the Turkish Penal Code, requires a minimum sentence of at least 10 years of imprisonment and a judicial fine ranging from one thousand to twenty thousand days.

• The competent court is the High Criminal Court , and the risk of the suspects being directly arrested is extremely high.

• In the case of alternative execution methods focused on impunity or supervision under Article 191 of the Turkish Penal Code, the competent court is the Criminal Court of First Instance .

• The most critical legal defense in favor of the defendant during the trial process is to prove that the act was within the scope of personal use and not trade, thereby changing the classification of the drug offense .

The Dilemma of Offering and Mediation

One of the most common risks in practice is the sharing of drugs free of charge within a social setting or among friends. The phrase "giving to another" in the legal text does not require a material gain. Therefore, if someone offers drugs to a friend free of charge, this could technically be considered "giving to another" under Article 188 of the Turkish Penal Code and lead to an investigation for drug trafficking. The line between joint drug use and obtaining and distributing the substance must be clearly established with legal and technical evidence.

What does this mean?

The state views individuals who self-use drugs as needing treatment and offers them probation to recover without going to prison. However, when the drug is given to another person, transported, sold, or offered to a friend, the situation immediately transforms into a serious commercial crime punishable by at least 10 years in prison. Therefore, correctly analyzing the act as if it were solely "drug use" is of vital importance.

The 5 Key Criteria Established by the Supreme Court of Turkey for Distinguishing Between Use and Commercial Use

In criminal proceedings, when evaluating whether an act constitutes possession of drugs for personal use or drug trafficking , concrete evidence and established Supreme Court criminal general assembly rulings regarding the amount of drugs to be used are taken into account, rather than abstract allegations.

According to the precedents of the Supreme Court of Appeals, the following five fundamental criteria are considered decisive in determining the nature of a crime:

1. Quantity of Substance and Forensic Medicine Institute Dosage Reports

The quantity of the substance found on or in the possession of the individual is the most fundamental criterion.

However, the answer to the question of what the personal use limit for drugs is in grams is not a single number; it varies depending on the type of substance and the forensic medicine institution's drug purity analysis.

• For example, when asked what the personal use limit is for cannabis , the Supreme Court considers an average of 600-700 grams of cannabis per year to be a reasonable limit for personal use.

• However, with high-dose drugs like cocaine, heroin, or methamphetamine , the daily drug use dose is calculated according to forensic data, and even much lower amounts can be interpreted as exceeding the personal use limit.

2. Location and Packaging Method of the Substance

It is examined whether the item is stored as a single piece or in a state ready for distribution:

• Being caught with packaged drugs , especially if the substance is divided into small aluminum foil packets, paper bags, or resealable zip-lock bags of equal weight, is strong evidence of intent to traffic.

• However, the seizure of a precision scale and packaging materials along with drugs during a search, and the finding of a precision scale in the home, can be considered direct evidence of drug trafficking according to the Supreme Court's jurisprudence.

3. Diversity of Substances

Drug addicts or users generally turn to a single type of substance. The presence of multiple substances with completely different properties and mechanisms of action, such as cannabis, synthetic cannabinoids (bonzai), methamphetamine, and cocaine, on a perpetrator's person or in their residence at the same time, is considered by the Supreme Court as an indication that the substance is present for purposes beyond personal use and for market distribution.

4. Suspect's Behavior and HTS/Communication Records

The method by which the perpetrator evades, swallows, throws out a window, or hides the substance upon seeing law enforcement officers during an operation or inspection, as well as communication data, are recorded in the file. This is where the question of whether HTS (Historical Telephone Records) constitutes evidence of drug trafficking comes into play; historical base station data, suspicious money transfers in bank accounts, and buyer-seller conversations via SMS or instant messaging applications are critical evidence in proving intent to trade.

5. Determining Whether the Perpetrator is a User

Detection of the drug substance in urine, blood, or hair samples taken at the time of arrest proves that the perpetrator is an active user. Even if a person tests negative in biological tests and is determined not to be a user, the seizure of the substance, even within the limits for personal use, increases suspicion of drug trafficking; however, in the case of active users, the defense can be supported by technical evidence, potentially shifting the charge from drug trafficking to personal use .

What does this mean?

The court doesn't just look at the question of "How many grams were found in his pocket?" Was the substance in a single bag, or was it divided into small pieces for sale? Was there a sensitive scale at home? Was the substance found in the person's blood, or was he carrying a large quantity without ever using it? The Supreme Court combines all these pieces of evidence to determine whether the person is a "user" or a "seller."

Investigation Phase: Search Warrants, Illegally Obtained Evidence, and Detention Process

Drug investigations often begin as a result of spontaneous patrols, tip-offs, or planned operations by law enforcement. However, even if incriminating materials are seized in an operation, adhering to procedural rules in criminal proceedings is as essential as uncovering the material truth.

Legality of Search Operations and the Requirement for a Search Warrant

According to Articles 116 and subsequent articles of the Code of Criminal Procedure (CMK), a person's belongings, residence, or vehicle may only be searched with a duly authorized court order or, in cases where delay would be detrimental, with a written order from the public prosecutor.

• In cases where drugs are found during a body search or in a vehicle , the legal boundaries between the police's authority to stop and prevent a search and their authority to conduct a judicial search are frequently violated.

• In a legal review of a drug search conducted at home , the scope of the search warrant, the presence of procedural witnesses such as village elders or neighbors who must be present during the search, and the validity period of the warrant are meticulously examined.

The Concept of Illegally Obtained Evidence and the Approach of the Supreme Court of Turkey

According to Article 38/6 of the Constitution and Article 217/2 of the Code of Criminal Procedure, findings obtained unlawfully cannot be accepted as evidence in criminal proceedings.

• In investigations, the question frequently asked is what happens if a police search is unlawful. The answer is very clear in criminal law: Items seized as a result of an unlawful search constitute illegally obtained evidence.

• According to established Supreme Court rulings on illegal searches and drug-related acquittals , evidence obtained illegally cannot be used as grounds for conviction; if there is no other concrete and legally admissible evidence in the case file, the defendant should be acquitted.

The Detention Process, Interrogation, and Appeals Against Arrest: From the moment the drug-related detention process begins, the suspect has the right to remain silent, the right to appoint legal counsel, and the obligation to notify their relatives of the arrest.

• Whether the presence of drugs in urine and blood tests constitutes evidence is clarified through biological samples obtained with the suspect's consent or through a properly conducted physical examination order issued in accordance with the Code of Criminal Procedure.

• If, after the suspect is referred to the courthouse, the conditions for arrest on drug charges are not met, instead of direct arrest , judicial control measures (travel ban, mandatory signing in, etc.) should be requested in the drug operation .

• Against unjustly issued arrest warrants, an appeal must be filed with a higher court within the prescribed time limit, including a petition challenging the arrest on charges of drug trafficking, presenting concrete objections on both procedural and substantive grounds. At this stage, ensuring the process is conducted within a legal framework and the importance of legal representation in drug-related crimes prevents irreparable loss of rights.

What does this mean?

Police have very strict legal rules for stopping and searching someone or entering their home. Items seized without a proper search warrant may be considered "illegally obtained evidence." Evidence obtained illegally cannot be used against a defendant in court; this could completely alter the course of the trial.

The Management of the Legal Process in Drug Crimes and the Role of Law Firms

Criminal investigations and prosecutions involving drug-related charges are highly technical processes that are not based solely on the circumstances of the incident, but also involve forensic reports, criminal analyses, digital examinations, and strict procedural rules. In this process, establishing the case on the correct legal grounds is crucial for the suspect's or defendant's freedom.

Accurate Determination of the Nature of the Crime and Defense Strategy

Investigating authorities often tend to open cases directly under Article 188 of the Turkish Penal Code (drug trafficking) due to the quantity or manner of seizure of the substance.

• In criminal courts handling drug cases , the most crucial defense strategy for a defendant is to demonstrate, by citing the specific circumstances of the case and precedents set by the Supreme Court regarding personal use, that the act falls within the realm of personal use, not trafficking.

• By presenting case examples of Supreme Court reversal decisions on drug trafficking and technical defenses , the nature of the crime can be changed from trafficking to drug use ; thus, the individual can be placed under treatment and supervised release instead of facing prison sentences exceeding 10 years.

• Furthermore, if the conditions are met, the applicability of the provisions on effective repentance (Article 192 of the Turkish Penal Code) in drug offenses is evaluated, and avenues for sentence reduction or exemption from punishment are examined.

Requests for Technical Review and Criminal Report

Allegations in criminal cases should be based on concrete scientific data, not assumptions.

• The Forensic Medicine Institute is requested to monitor the drug purity level analyses and compare the net amount of active substance in the report with the perpetrator's daily usage needs.

• When investigating whether HTS (Historical Telephone Records) constitute evidence of drug trafficking , the statements of those who contacted the suspect, base station signals, and message content are analyzed in detail to try to prove that there was no intent to traffic.

Auditing Procedural Safeguards and Eliminating Illegally Obtained Evidence

From the very beginning of the investigation, the police's actions of arrest, search/vehicle/house search, and seizure are reviewed for compliance with the Code of Criminal Procedure. The goal is to ensure that evidence obtained through procedural irregularities is removed from the file, thereby achieving an acquittal in drug trafficking cases. At this point, professional monitoring of the process and the importance of a lawyer in drug-related crimes prevent irreparable harm to rights.

What does this mean?

Drug charges involve technical, criminal, and procedural details. An investigation initially launched on suspicion of "trading" can be decisive in determining whether the offense remained within the scope of "use," based on a proper analysis of the concrete evidence in the case. This can lead to the individual benefiting from treatment or probation instead of potentially lengthy prison sentences.

Are you experiencing a situation like this?

Investigation and prosecution processes involving drug-related charges consist of extremely sensitive, technical stages with irreversible consequences, from the collection of evidence to the determination of the nature of the crime. To avoid any loss of rights from the very beginning of the investigation, to have the legality of the evidence reviewed, and to ensure the case is evaluated within the framework of Supreme Court precedents, it is vital to consult with a competent criminal law expert.

Frequently Asked Questions (FAQ)

What is the legal limit for personal use of drugs in grams?

The law does not specify a fixed gram limit; the limit is calculated based on the type of substance seized, the purity level determined by the Forensic Medicine Institute, and the annual personal consumption amount of the perpetrator.

Does having a precision scale or resealable bags at home count as trading?

The presence of materials such as the substance being packaged/divided, sealed bags, and a precision scale is considered among the strongest evidence indicating commercial intent in the practice of the Supreme Court of Turkey.

Is a positive blood or urine test grounds for immediate arrest?

The detection of the active substance in biological tests confirms that the perpetrator is a "user". If there is no other concrete evidence of commercial activity in the file, the act falls under Article 191 of the Turkish Penal Code, and the public prosecution is postponed, with supervised release applied.

Can drugs seized as a result of an illegal search be considered evidence?

Items obtained through irregular searches of persons, vehicles, or homes without a court order or prosecutor's decision constitute illegally obtained evidence; according to Supreme Court precedents, they cannot be used as grounds for conviction and may constitute grounds for acquittal.

Can a drug trafficking case (Article 188 of the Turkish Penal Code) be converted into a drug use case (Article 191 of the Turkish Penal Code)?

Based on the examination of the criminal reports, forensic analyses, and HTS records in the file in accordance with the criteria of the Supreme Court, it is possible to change the nature of the crime from commerce to usage and open the way for impunity/treatment.
