Is Cannabis Legal in Thailand?
Is cannabis legal in Thailand? Only for medical purposes. Since 26 June 2025, Public Health Minister Somsak Thepsuthin's ministerial notification reclassified cannabis flower as a "controlled herb." Any product above 0.2% THC now requires a PT 33 prescription, valid for 30 days with a commonly reported cap of 30 grams per month. CBD products below 0.2% THC remain freely available without any prescription. The recreational era is over. Of the 18,433 dispensaries that once operated, 7,297 have closed. Only 11,136 licensed dispensaries remain, and roughly half of the ~12,000 licenses currently valid are reported to expire during 2026 (Bangkok Post; unverified). Tourists and Thai nationals alike can access cannabis through the PT 33 system, but foreign prescriptions are not accepted. Possession without a valid prescription carries fines up to 25,000 THB and up to 3 months in jail.

The PT 33 Prescription System
The PT 33 (known in Thai as ปท. 33) is Thailand's official prescription for cannabis products above 0.2% THC. Only seven categories of DTAM-certified practitioners can issue one: medical doctors, traditional Thai medicine practitioners, applied Thai traditional medicine practitioners, traditional Chinese medicine practitioners, pharmacists, dentists, and licensed folk healers (veterinarians may prescribe for animals only, not people). Each prescription is a paper form specifying strain, dosage, and duration, stays valid for 30 days, and is commonly reported to allow up to 30 grams per month. You can fill it at any licensed dispensary in the country. Foreign prescriptions are not valid. Read our complete PT 33 prescription guide for the step-by-step process, costs, and clinic locations.
Cannabis Penalties in Thailand
Thailand enforces cannabis violations with real consequences. Here are the specific penalties:
| Offense | Penalty | Severity |
|---|---|---|
| Public smoking or creating a nuisance | Fine up to 25,000 THB and/or up to 3 months imprisonment under the Public Health Act B.E. 2535 (1992), even with a valid prescription | Medium |
| Selling without a prescription or licence | Up to 1 year imprisonment and/or a fine up to 20,000 THB under the Traditional Medicine Act B.E. 2542, plus administrative licence suspension or closure | High |
| Possession without a PT 33 prescription | Commonly reported at up to 25,000 THB fine and/or up to 3 months imprisonment — verify with authorities | High |
Selling to minors, unlicensed cultivation, and driving under the influence are also offenses, but the exact penalty figures are unverified pending Thai legal review, so we do not state them here. These penalties are based on current ministerial notifications and the underlying statutes. The Cannabis & Hemp Act, still pending in parliament, may revise them. Verify current rules with local authorities before acting.
Can Tourists Buy Cannabis in Thailand?
Yes, but only through the official system. Tourists need a PT 33 prescription from a licensed Thai clinic to buy any product above 0.2% THC. Foreign prescriptions are not accepted. CBD products under 0.2% THC can be purchased freely without a prescription. One critical warning: do not take cannabis out of Thailand. It remains illegal in most neighboring countries, and customs enforcement at airports is active. Read our complete tourist cannabis guide for clinic locations, costs, and border rules.
Cannabis Business Licensing
Every cannabis business in Thailand must hold a license from the Thai FDA. This covers dispensaries, clinics, farms, and manufacturers. Since January 2026, dispensaries must also have a certified medical practitioner on-site during all operating hours. The industry is shrinking: 7,297 shops have already closed, and roughly half of the ~12,000 licenses currently valid are reported to expire during 2026 (Bangkok Post; unverified). Farms require GACP certification and product tracking. Read our cannabis farming guide for cultivation-specific licensing details.
The Cannabis & Hemp Act: Where Things Stand
Thailand's Cannabis & Hemp Act, intended to be the country's comprehensive cannabis legislation, has still not passed parliament as of July 2026. The bill cleared an early reading but stalled before the readings needed to become law. The Ministry of Public Health ran a formal public consultation on the draft from 22 April to 21 May 2026, and the government has signaled it wants the Act passed before the end of 2026 — though that timeline remains uncertain.
Without this Act, all current cannabis rules rest on ministerial notifications and administrative orders from the Ministry of Public Health. These carry legal weight but can be changed faster than parliamentary law. Until the Act passes, expect the rules to keep changing.
Key provisions in the proposed Act:
- • Codifies the minimum purchase and possession age at 20
- • Designates cannabis-free zones around temples, schools, and government buildings
- • Standardizes licensing across dispensaries, clinics, farms, and manufacturers
- • Establishes a seed-to-sale tracking system for all cannabis products
- • Sets statutory penalties replacing current ministerial-level enforcement
