The Lab Report Says Synthetic Cannabinoid: the word that raises a Turkish drug sentence by half

Article 188/3 of the Turkish Criminal Code (TCK) covers what most files are actually about: selling, offering for sale, giving to another, dispatching, transporting, storing, buying, accepting or possessing a controlled substance inside the country, without a licence or contrary to one. The sentence is not less than ten years, together with a judicial fine of one thousand to twenty thousand days. Article 188/1, for import, export or manufacture, is twenty to thirty years and a fine of two thousand to twenty thousand days.

Article 188/4-a then does one thing. Where the substance in any of those paragraphs is heroin, cocaine, morphine, base morphine, synthetic cannabinoid and its derivatives, synthetic cathinone and its derivatives, synthetic opioid and its derivatives, or amphetamine and its derivatives, the sentence to be imposed is increased by half. Law no. 6638 added synthetic cannabinoids and their derivatives on 27 March 2015; the paragraph took its present form on 28 March 2023, when Law no. 7445 extended it to synthetic cathinone, synthetic opioid and amphetamine derivatives.

Two separate questions sit behind that single word, and they are answered from different documents.

The first is whether the substance is controlled at all. Substances are brought within the scope of Law no. 2313 on the Control of Narcotic Substances by decisions carrying an annexed list, issued periodically as new molecules appear; the most recent is the Presidential Decision of 9 January 2026, no. 10851, and there is a long line of earlier ones going back through 2018, 2017 and 2016. The date matters, because article 2/1 TCK allows no penalty for conduct the law does not expressly make an offence. What was on the list on the day of the alleged act is a checkable fact, not an assumption.

The second question is which family the molecule belongs to. Article 188/4-a names chemical families, never products. Street names carry no legal weight at all: bonzai, jamaika and spice appear in police statements and in the press, but the paragraph is engaged by the laboratory's identification of the compound and by its placement in the synthetic cannabinoid family. Article 2/3 TCK forbids analogy in the application of criminal provisions and forbids interpreting them so broadly that analogy results. Whether a newly synthesised compound is a derivative of a listed family is therefore a chemical question with a legal consequence, not an impression drawn from how the substance was sold or what effect it produced. The multiplier it triggers is what separates a fifteen-year floor from a ten-year one in a trafficking prosecution under article 188.

Article 20 of Law no. 2313 sets out how the material reaches the laboratory. Substances seized are taken under a written record; enough of the material is then taken as a sample to permit analysis and sent to the relevant laboratory so that the type, quality and quantity may be established definitively. Once the definitive reports are in, confiscation is ordered by the criminal judge of peace at any stage of the investigation, on condition that samples are retained in the manner set by regulation. Those retained samples are confiscated with the judgment itself and handed over to the local civil authority only after the judgment becomes final. The practical consequence is that, while your case is live, the material a second analysis would need normally still exists.

The expert is appointed under article 63 of the Code of Criminal Procedure (CMK), which permits an expert opinion where the matter requires expertise or special or technical knowledge; the judge or court decides on the appointment and on the number of experts, and the prosecutor exercises the same powers during the investigation. Article 67/3 draws the boundary that is easy to miss when you read a report in a language you do not speak: the expert may not make statements outside the matters requiring expert or technical knowledge, and may not make the legal characterisations and assessments that belong to the judge. A report can say that a compound is a synthetic cannabinoid. It cannot decide that what you did was supply rather than possession for your own use; that characterisation is the court's.

The Code gives you a short, specific window rather than a general right to argue. Under article 67/4 CMK, copies of the report may be handed to the accused and to defence counsel during the hearing, or sent to them by registered post. Article 67/5 is the operative one: when the expert examinations are complete, a period is given to the prosecutor, the accused and defence counsel so that they may request a fresh expert examination or state their objections, and if such a request is refused, a reasoned decision on the refusal must be issued within three days. Article 67/6 adds a route that does not depend on the court's permission at all — you may obtain a scientific opinion from a specialist of your own, either to be taken into account in the preparation of the report or about the report once it exists. No additional time may be requested on that ground alone, which is why the specialist has to be instructed as soon as the report lands, not after the period has run.

The third moment is the hearing. Article 68 CMK allows the court to call the expert to explain the report in court, either of its own motion or at the request of a party, and the same provision applies to the specialist who prepared your scientific opinion. A classification that survives written objection sometimes does not survive being explained aloud.

If the finding stands at judgment, the route is istinaf: article 273/1 CMK requires the application to be made within two weeks of the date the judgment, with its reasoning, is served on you, by petition to the court that gave it or by a declaration recorded by the clerk. Classification is only one of the things a forensic report settles — type, weight and purity are three separate findings, each attacked differently, and each covered on our page on the forensic report that decides a drug case.
