Is Xylazine legal in Thailand?

Legal status

Xylazine is not named in Thailand's criminal drug schedules. A substance specific sweep, run in Thai and by chemical name, found no entry for it in the Thai FDA table of controlled narcotic drugs updated 15 September 2025 and none in the B.E. 2565 psychotropic naming notifications, and no generic analogue clause was identified in the naming model that would reach it without naming it. Xylazine returned no entry, and it is a veterinary sedative rather than a scheduled narcotic under what was read. That is a positive finding on a closed list rather than an unresolved search: Thai control is delegated to notifications that name substances one by one, so what the notifications do not name sits outside the Narcotics Code's categories until one names it. It is not a finding that Xylazine is uncontrolled in Thailand. Two instruments were searched, the Thai FDA Table of Controlled Narcotic Drugs updated 15 September 2025 and the Ministry of Public Health psychotropic naming notifications of B.E. 2565, and Thailand also controls medicines through the Drug Act B.E. 2510, which this reading did not open. Which tier of that Act, if any, reaches Xylazine is not established here.

Consequences if caught

Capital exposure: none. No death penalty and no life term arises for Xylazine under the Narcotics Code, and the reason is structural rather than lenient: the Narcotics Code's penalties attach to a scheduled category, the sweep placed this substance in none of them, and with no Category I, II, IV, V or psychotropic entry there is no section 145, 146, 148 or 149 ceiling to state at all. No capital or life exposure under that Code attaches to a closed list negative finding. The sweep that produced this ran across two instruments and no others, the Thai FDA Table of Controlled Narcotic Drugs updated 15 September 2025 and the Ministry of Public Health psychotropic naming notifications of B.E. 2565, so it is an absence from those two and not a finding that Xylazine is uncontrolled in Thailand. What it does not cover is the Drug Act B.E. 2510, the separate medicines statute with its own tiers and its own penalties, which this reading did not open, so which tier of that Act reaches Xylazine, if any, is not established here. Xylazine is a veterinary sedative rather than a scheduled narcotic under what was read, so a veterinary medicines route is where a figure would come from and that route was not opened.

If prescribed or medical

No entry for Xylazine was found in either of the two instruments that were searched, the Thai FDA Table of Controlled Narcotic Drugs updated 15 September 2025 and the Ministry of Public Health psychotropic naming notifications of B.E. 2565, so no narcotic or psychotropic schedule places it and none can carry a prescription route. That is an absence from those two instruments and it is not a finding that Xylazine is uncontrolled in Thailand. Thailand's country level traveller rule for personal medication was not established by this reading. The sources opened were the Narcotics Code B.E. 2564, the Thai FDA narcotics table updated 15 September 2025 and the B.E. 2565 psychotropic naming notices in the Royal Gazette, and the dossier is explicit that its findings come from those naming instruments and not from a traveller permit label, so no import permit route, no personal supply quantity ceiling and no certificate requirement can be stated here for Xylazine. Thailand controls medicines separately under the Drug Act B.E. 2510, and that Act and its tiers were not opened by this reading, so whether Xylazine is a prescription only medicine, a restricted import or freely carried under it is not established here. What is missing from this row is the permission, not the classification, and the gap is in what was read rather than a finding that no lawful route exists. This is not dispensed to people at all, so what this row leaves unanswered is a veterinary supply question rather than a traveller prescription one.

Documentation

Carry the distinction this row rests on: the finding for Xylazine is an absence from the Thai FDA Table of Controlled Narcotic Drugs updated 15 September 2025 and from the Ministry of Public Health psychotropic naming notifications of B.E. 2565, which is not a clearance under Thai law generally, so any paperwork it needs would come from the Drug Act B.E. 2510 rather than from the Narcotics Code, and this reading did not open that Act to say which of its tiers, if any, applies. Keep the veterinary framing, because a human medicines check would not find this compound and the instruments read here did not find it either. The reading was taken on 20 September 2026 from the consolidated narcotics table, read alongside the psychotropic naming notices, at https://narcotic.fda.moph.go.th/media.php?id=808160206197497856&name=NARCO+list+(update+15.09.2025)+NEW.pdf.

The names and categories are set by ministerial notification, and the publications do not certify that no later notification exists, so re-read before relying on this.

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