Is cannabis legal in Thailand? Not anymore. The answer changed on June 25, 2025, when the Ministry of Public Health placed the flower back under medical control: since then, it can only be purchased with a Thai prescription, and recreational use is prohibited. Many travelers still leave with the image of neon-lit dispensaries on Khao San Road, and it is precisely this disconnect that causes problems. At Tealer420, we have been following cannabis in Thailand since the 2022 decriminalization, and here we summarize what is truly in effect as of September 24, 2026.
| Situation | Status | What you risk |
|---|---|---|
| Smoking for pleasure | Prohibited | Legal consumption only with a prescription |
| Smoking in the street or a park | Public nuisance | Up to 3 months and/or 25,000 baht |
| Buying without a prescription | Illegal | Exact penalty varies by source |
| Buying with a PT 33 prescription | Legal | Prescription for a maximum of 30 days |
| Arriving with your own cannabis | Import prohibited | Narcotics criminal law |
| Leaving with cannabis | Export prohibited | 30,000 baht per kilo, potential detention |
| Extracts over 0.2% THC | Category 5 narcotic | Criminal prosecution without a license |
Cannabis in Thailand: what changed in 2025
The turning point boils down to one date: the notification from the Ministry of Public Health on June 25, 2025, which went into effect on the 26th. It reclassified the flower as a "controlled herb," sellable only by prescription. In concrete terms, three things changed overnight:
- Recreational use is once again prohibited. Consumption is only legal within the framework of a prescription.
- Purchase requires a paper prescription (form PT 33), issued at a clinic or hospital, valid for 30 days and non-renewable.
- Shops must verify every prescription and declare their sales every month.
The crackdown continued in 2026. A regulation dated April 30 restricted flower sales licenses to healthcare professionals, with dedicated storage and odor/smoke control requirements. And since October 2025, 84 licenses have been suspended.
From the 2022 boom to the backlash
To gauge the shift, one must remember where the country came from. In 2018, Thailand became the first in Asia to legalize medical cannabis. On June 9, 2022, it removed the flower from the list of narcotics: about 4,200 prisoners were released, and the country became covered in dispensaries.
However, the framework remained vague from the start. In February 2024, authorities already considered that possession of more than 30g indicated an intent to sell. Then came the U-turn of 2025. In February 2026, out of 18,433 registered shops, 7,297 had closed their doors.
Thus, in three years, Thailand went from a symbol of openness in Asia to one medical regime among many. The contrast with its neighbors remains huge, however: in a large part of the region, trafficking can still lead to the death penalty, which Thai law does not provide for cannabis flowers. We have put the entire region into perspective in our dossier on Asia and the Middle East.
On the ground: prohibitions to know
Even with a prescription in hand, freedom is limited. Here is what remains prohibited:
- Smoking in public spaces, and especially near temples, schools, and parks. This is a nuisance under the Public Health Act.
- Buying online or in a vending machine: these channels are prohibited.
- Buying if you are under 20 years old, pregnant, or breastfeeding.
- Presenting a foreign prescription: it is not recognized.
On the ground, enforcement remains uneven. Clinics attached to certain shops issue "convenience" prescriptions to tourists for reasons like insomnia or anxiety. This is exactly what authorities are targeting today, and a dispensary caught in violation risks up to 1 year in prison or a 20,000 baht fine.
Bangkok airport, the real danger
The Thai boom had a side effect few travelers are aware of: it fueled massive trafficking toward Europe. The British National Crime Agency arrested 976 cannabis smugglers at UK airports in 2025, compared to 142 in 2023, many coming from Bangkok. In total, 28 tons were seized from air passengers in 2025.
Thailand reacted. Since June 17 and 18, 2026, customs has imposed a fine of 30,000 baht per kilo (approximately 790 euros) on any attempt to export. For an average smuggler carrying 26 kg, this represents about 17,700 pounds, or up to 2 years of detention in case of non-payment. The French Ministry of Foreign Affairs mentions sentences of 2 to 10 years and numerous Europeans currently in pre-trial detention.
Upon arrival in France, the situation does not improve: bringing back cannabis constitutes importing narcotics, an offense on a completely different scale than the simple usage sanctioned by a fixed penalty fine.
The Cannabis and Hemp Act, a law still under construction
Beware of articles announcing a new Thai law "adopted in July 2026": it is false. On July 21, 2026, the Cannabis and Hemp Act draft was merely submitted to the Minister of Health, following a public consultation from April 22 to May 21, 2026. It still needs to pass through the Council of Ministers and then Parliament.
As long as the text is not voted on, its content (possession, home cultivation, sanctions) may change. The status of home cultivation declared via the Plookganja app since 2022, in particular, is not clearly decided.
Key Takeaways
Thailand is no longer the country of open-access cannabis. Since June 2025, it has been a strict medical regime based on Thai prescriptions, reinforced by 2026 regulations and customs officials who have turned the airport into a high-risk zone.
For a traveler, the line is clear: no Thai prescription, no legal purchase. No smoking in public. And nothing in the suitcase, either going or returning.

No. The capital punishment exists in Thai law for other narcotics, but not for cannabis flowers. Sanctions remain heavy for exporting.
