Cannabis in Thailand

On June 26, 2025, Thailand reversed the 2022 partial legalization with a Public Health Ministry order requiring a medical prescription for every purchase. In January 2026, the rules tightened further: every dispensary must now have a certified medical practitioner on-site. Around 7,300 shops closed by February 2026 after failing to meet the new licensing standards.

PT33 is the specific Thai prescription form used for cannabis and other controlled herb products. It's issued by a Thai-licensed practitioner, valid for up to 30 days, and required at the dispensary counter. There is no equivalent foreign-recognized form.

On private property only, with the prescription holder. Public consumption (streets, beaches, hotel grounds with no-smoking policies) is not permitted. Recreational use carries up to 1 year imprisonment and a 20,000 baht fine.

No — and the risk is greater now. Possession is illegal in nearly every country tourists travel to from Thailand, including the US, UK, Australia, and most of the EU. Customs at Suvarnabhumi and Chiang Mai actively check outbound travelers, and Thailand's own re-criminalization makes carrying it through the airport a domestic offense too.

CBD products with low THC content, and specific Thai FDA-approved THC edibles, remain legal at licensed retailers. The Thai FDA has approved a small number of THC products for consumer sale (e.g., specific Baked Brand cookies and caramels). General recreational flower and concentrate sales are not legal without prescription.
