Drug Possession in Turkey: Personal Use or Trafficking? Articles 188 and 191, Sentencing Gap and Effective Remorse

In a drug case the most critical question is often this: was the substance kept for personal use, or was there an intent to traffic? That distinction alone decides whether the sentence is two to five years or at least ten years. For the user the law opens deferral of prosecution and treatment; for trafficking there is no such option.

This guide explains the difference between Articles 188 and 191 of the Turkish Penal Code (Law No. 5237), the factors courts weigh in drawing the line, the effective remorse options under Article 192 and a 2025 decision of the 10th Criminal Chamber of the Court of Cassation. For deferral and probation details, see our guide on probation in drug offences.

1. Two Offences, Two Different Worlds: Articles 191 and 188

Article 191/1: A person who buys, accepts or possesses drugs or stimulants for personal use, or who uses them, is punished with imprisonment from two to five years.

Article 188/3: A person who sells, offers for sale, gives to others, dispatches, transports, stores, buys, accepts or possesses drugs or stimulants without a licence or in breach of a licence within the country is punished with imprisonment of not less than ten years and a judicial fine of 1,000 to 20,000 days. For manufacture, import or export the sentence is twenty to thirty years (Art. 188/1).

So the same act (possessing the substance) becomes two different offences depending on purpose. If the purpose is personal use, the offence falls under Article 191.

2. The Chance Given to Users: Deferral of Prosecution and Probation

For possession for personal use, in the investigation the filing of the public case against the suspect is deferred for five years, without the conditions of CMK Art. 171 being required (TPC Art. 191/2). During the deferral a probation measure of at least one year is applied; this can be extended by six-month periods up to a further two years (Art. 191/3). Treatment may be applied where necessary, and the suspect is referred for drug testing at least twice a year.

If the obligations are not complied with, or the person again possesses drugs for use, the case is filed (Art. 191/4). Being treated as a "user" therefore opens a way to avoid a sentence; being treated as a "trafficker" closes it. In many files, the defence is built around this distinction.

3. Factors Courts Weigh in Practice

The law sets no numerical threshold between use and trafficking. Courts look at the facts of each case. In practice the following are weighed together:

• Quantity: An amount clearly above personal use strengthens suspicion of trafficking, but is not by itself regarded as sufficient.
• Packaging and items seized: Substance divided into small portions or packed separately; precision scales, bags, scissors.
• Whether the person is a user: Test results, health records, paraphernalia and the person's own statement.
• Signs of sales: Messages, phone and call-record data, money movements, witness or informant statements.
• Place and circumstances: Found at home, in a vehicle or on the person; how it was hidden.
• Prior record for similar offences.

What matters is whether there is conclusive and sufficient evidence of an intent to sell or give to others. Suspicion is not enough for conviction; doubt benefits the defendant.

4. What the Court of Cassation Says: Intent to Sell Must Be Proven by Conclusive Evidence

In the 2025 decision below, the 10th Criminal Chamber found, for two defendants convicted by the assize court of trafficking, that there was no conclusive and sufficient evidence beyond reasonable doubt that they kept the seized drugs for a purpose other than use, such as selling or giving them to others, and characterised the proven act as "possession of drugs for personal use". Because a deferral of the pronouncement of judgment had already been ordered in a separate file for that act, the Chamber quashed the convictions of those two defendants and upheld the judgments against the others.

The decision shows two things: proving trafficking requires conclusive evidence, not assumption, and the defence should argue that, where evidence is lacking, the act falls under Article 191.

5. Effective Remorse: Article 192

Article 192 opens several doors:

• Participants in trafficking (Art. 192/1): if, before the authorities learn of it, the person reports the other accomplices and the places where the drugs are hidden or manufactured, and the information leads to the arrest of the accomplices or seizure of the drugs, no penalty is imposed. Voluntary help after the authorities learn of the offence reduces the sentence by one quarter to one half (Art. 192/3).
• Possessors for personal use (Art. 192/2): if, before the authorities learn of it, the person reports from whom, where and when the substance was obtained and thereby facilitates the arrest of offenders or seizure of the drug, no penalty is imposed.
• Applying for treatment (Art. 192/4): a drug user who, before an investigation is opened for possession for use, applies to the authorities or a health facility to be treated is not punished; in that case public officials and health professionals have no duty to report.

The shared condition is timing: the step must be taken before the authorities learn of the offence or the investigation starts. Otherwise only a limited reduction may be possible.

6. First Steps If You Are Detained

Conduct in the first hours of a drug investigation shapes the file:

• Ask for a lawyer and do not make a statement without one. The right to counsel comes from the law; read the statement before signing.
• State clearly and consistently whether the substance is yours and kept for personal use; this is the key defence line against a trafficking allegation, but what you say should be decided with your lawyer according to the file.
• Check the search warrants for your phone and home; the lawfulness of a search affects whether the evidence can be used.
• Follow the testing and report process; health documents showing you are a user matter for the distinction.

7. Common Mistakes

• Not stating you are a user in the first statement: a later defence appears less credible.
• Treating quantity as decisive on its own: other evidence of trafficking is also required.
• Missing the effective remorse window: once the investigation has started, full exemption is no longer available.
• Not complying with deferral conditions: breach of probation obligations leads to prosecution.
• Ignoring phone and message records: these are usually the main evidence of a sale allegation.
