Is 4-HO-MET legal in Turkey?

Legal status

4-HO-MET is not confirmed as a controlled substance in Turkey and this row is a deferral rather than a finding. The dossier searched the Turkish terms «4-HO-MET» and «metosin» and the transliterations 4-HO-MET and metosin against the classification decisions made under article 19 of Law No. 2313 on the Control of Narcotic Substances, and confirmed no current entry. It rejected the near match «psilosin», because the ethyl analogue is not psilocin. The compound therefore sits one methyl group away from a molecule whose parent, psilocybin, is verified as scheduled on its own row, and a closed list does not bridge that distance without a decision that names the analogue. The annexes to the ten decisions footnoted to article 19, running to Presidential Decision No. 10851 of 9 January 2026, are not reproduced in the consolidated statute, so whether such a decision exists could not be established from what was read.

Consequences if caught

Capital exposure: none. No article in this chain carries a capital or whole life route, and no per-substance threshold was verified for this row. If a classification decision names 4-HO-MET, the ceiling is 30 years under article 188(1) of Penal Code No. 5237 with aggravating multipliers in article 188(4), (5) and (8), the domestic conduct floor in article 188(3) is not less than ten years, and article 191(1) sets two to five years for buying, accepting or possessing for use, with article 192(2) removing the penalty altogether from a user who names the supplier before the authorities have learned of the offence. If no decision names the compound, none of that reaches it. The uncertainty is the substance of this row and it is not resolvable from the consolidated text.

If prescribed or medical

There is no prescription route for 4-HO-MET in Turkey and no medicinal preparation exists anywhere. The dossier carried no prescription instrument for this row and no per-substance medical route is asserted here. Article 188(6) of the Penal Code reaches permission bound or prescription bound substances producing a narcotic or stimulant effect, and there is nothing before this row to satisfy either limb. An unconfirmed classification is not a medical status.

Documentation

Nothing documents an unconfirmed compound. On this row the practical point is that tryptamines sold as research chemicals are routinely mislabelled between close analogues, and only two of the family in this corpus are verifiably scheduled, DMT and psilocybin, so a mislabelled product can move a person from an unresolved position to a clearly scheduled one without any change in what they believed they had. The analysis under article 20 of Law No. 2313 is what decides it. The search log was read in the dossier on 18 September 2026 and article 19 of Law No. 2313 was read from the consolidated statute on 20 September 2026.

Drug laws and enforcement change and vary within a country. This is not legal advice. Always confirm with Turkey’s embassy or official drug authority before traveling; penalties can be severe, including imprisonment.
