Are Benzodiazepines legal in Thailand?

Legal status

Not applicable as a class status, and not because the notifications are silent about the members. Benzodiazepines is a class label rather than a single entry, and Thailand's scheme names molecules one at a time: this table answers six of them and they do not land together. Alprazolam and nimetazepam are psychotropic Category 2 under the B.E. 2565 naming notification. Diazepam, clonazepam and lorazepam are psychotropic Category 4 under the same notification. Etizolam is the sixth and it did not settle, because the search rejected alprazolam as a near entry on the ground that it is a different molecule, so its classification is open. Five placements across two categories plus one unresolved reach question cannot be compressed into one status, and those six rows, not this one, carry the placements.

Consequences if caught

Capital exposure: none. Neither a death penalty nor a life term is available for any benzodiazepine this table places, and the class ceiling is two figures rather than one: section 149 states a maximum of 7 years for the Category 2 members, alprazolam and nimetazepam, and 5 years for the Category 4 members, diazepam, clonazepam and lorazepam, with no death penalty, no life imprisonment and no quantity trigger in either. Section 145 paragraph 3, the only limb this dossier records as reaching life or death, governs Category I narcotics, and no benzodiazepine answered here is in Category I. Etizolam carries no stated ceiling at all, because its category was never proved. Any account that puts a Thai capital exposure on a prescribed benzodiazepine has merged the psychotropic categories with the narcotic ones.

If prescribed or medical

A benzodiazepine's position depends on which member is in the packet, so this row cannot state one prescription answer: Category 2 placement carries a different section 149 maximum from Category 4, and etizolam has no proved placement at all. Thailand's country level traveller rule for personal medication was not established by this reading, which opened the Narcotics Code B.E. 2564, the Thai FDA narcotics table updated 15 September 2025 and the B.E. 2565 psychotropic naming notices, none of them for an import permit route, a personal supply quantity ceiling or a certificate requirement. The dossier is explicit that these are naming instruments rather than traveller permit labels, so the permission is what is missing here and not the classification.

Documentation

Carry the member level answer rather than the class: check which benzodiazepine is actually prescribed, read that substance's own row for its category and its section 149 maximum, and note that etizolam has no settled placement to read. Bring the prescription, the original dispensing packaging and a doctor's letter naming the patient, the active ingredient, the dose and the treatment period, treating them as necessary rather than sufficient because no Thai traveller route was established here. The reading was taken on 20 September 2026 from the Royal Gazette psychotropic naming notification carrying all five placed members, at https://www.ratchakitcha.soc.go.th/DATA/PDF/2565/E/182/T_0008.PDF. No express open reuse licence was located on the cited page, so only the wording needed for verification is reproduced, with attribution and a direct link. 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.
