Verified 10 July 2026. If your mental model of Thai cannabis was formed between 2022 and 2024 — walk-in shops, menus on the sidewalk, no questions asked — it is now wrong in one important way. Since 26 June 2025, buying cannabis flower in Thailand legally requires a certificate from a licensed practitioner. The shops didn't all vanish, but the legal basis they operate on did change, and it changed again in January 2026. This page tracks what is actually true now, with sources, and we update it when the rules move.

What changed, in order

June 2022 — Thailand removed cannabis from its narcotics list, the first country in Asia to do so. A retail boom followed: by 2025 there were roughly 18,000 licensed dispensaries nationwide.

26 June 2025 — the Ministry of Public Health's Controlled Herbal Medicine announcement (B.E. 2568) took effect. Cannabis flower became a controlled herb: sales are restricted to medical and health purposes, and buyers need a certificate — commonly called a PT33 — issued by a licensed medical professional. The certificate is valid for 30 days. It does not have to come from a conventional doctor: Thai-licensed dentists, pharmacists and traditional-medicine practitioners can also issue one (CNN, June 2025).

January 2026 — licensing tightened further: dispensaries face stricter renewal conditions, including having a certified practitioner available on site. Thai legal and industry sources report roughly 40% of the country's licensed shops — around 7,000 of 18,000+ — had closed or not renewed by early 2026.

The framework survived the change of government and remains in force as of 10 July 2026.

What this means if you're visiting

Dispensaries are still open and still legal — Bangkok alone has hundreds — but the transaction is now framed as medical. In practice, compliant shops arrange the certificate on site through their practitioner; the visit takes longer than 2023's walk-in-walk-out, and you should expect to state a health reason (sleep, pain, appetite are the common ones). Prices for the consultation vary by shop.

Three things have not changed: taking cannabis across any border remains a serious crime, public smoking remains a nuisance offence, and enforcement on the ground is uneven — some shops still sell as if it were 2024. That a shop will sell to you without paperwork does not make the purchase legal, and crackdowns have come in waves since mid-2025.

How our dispensary listings handle this

Every cannabis listing on this site now carries a dated legal notice. We are re-verifying the Bangkok dispensaries against the new rules — open/closed status, whether a practitioner is available on site, and how each shop handles certification. Listings show a "last verified" date; treat anything older than a few months as historical. Browse the current set at Bangkok cannabis dispensaries, and if you run a dispensary and your compliance status is wrong or missing, claim your listing — corrections are free.

Common questions, answered plainly

Is weed still legal in Thailand in 2026? Legal to buy with a practitioner's certificate, for medical or health purposes. Recreational retail as it existed 2022–2024 has no legal basis anymore.

Can tourists get the certificate? Yes — nothing restricts certification to Thai nationals, and many dispensaries arrange it in-house. Bring your passport.

Can I fly home with what I bought? No. Import and export are criminal offences everywhere on your route. Finish it or leave it.

Will the rules change again? Plausibly. Full recriminalisation was publicly discussed during 2025; the ministerial framework could be tightened or replaced by statute. That's what the alert box below is for.
