Is Weed Legal in Thailand? The 2026 Answer, Without the Hedging

Cannabis is legal in Thailand. It is also, since the middle of 2025, a lot more regulated than the internet thinks it is. Both of those things are true at once, and the gap between them is where most travellers get confused.

Here is the honest position as of late September 2026.

The short version

Cannabis is not a narcotic in Thailand. It was removed from the narcotics list in June 2022 and it has not gone back.

Cannabis flower is a controlled herb. That happened on 26 June 2025. A controlled herb can be sold, but only by a licensed shop, and only to someone holding a PT 33 prescription from a licensed practitioner.

So: legal, with a prescription, from a licensed shop. Not legal to grab off a shelf because a sign says open.

How we got here

June 2022, the door opens

Thailand delisted cannabis and became the first country in Asia to do so. What followed was fast and largely unregulated. Thousands of shops opened inside a year, because the delisting arrived well ahead of any framework to govern it. If you visited Thailand between 2022 and 2024, that is the country you saw, and it is the one most travel articles still describe.

June 2025, the door narrows

On 26 June 2025 the Ministry of Public Health reclassified cannabis flower as a controlled herb under the Protection and Promotion of Thai Traditional Medicine Wisdom Act B.E. 2542. From that date, a PT 33 prescription became a legal requirement for buying or holding flower.

This is the change that ended the open recreational market. It was not a ban. It was a reclassification, and the practical effect is that the transaction now runs through a practitioner.

April 2026, the shops get audited

Ministerial Regulation No. 2 B.E. 2569 came into force on 30 April 2026. It sets out what a licensed dispensary must actually have:

• Separated, quality-controlled storage
• Staff trained by the Department of Thai Traditional and Alternative Medicine on duty during all opening hours
• A qualifying licence
• Odour and smoke control
• Premises ownership or written consent from the owner

A lot of shops that had been coasting since 2022 could not meet this, and the number of dispensaries in tourist areas has been quietly falling since.

What this means if you are here now

You need two things.

A prescription. A licensed practitioner runs a consultation, typically about thirty minutes, and issues a PT 33 if it is appropriate. Tourists go through the same process and present a passport rather than a Thai ID card. Most people are sorted the same day. We cover the whole thing on our prescription page.

A licensed shop. The licence has to be displayed at the front of the premises. That is not a nicety, it is condition 1 on every licence issued. If you cannot see one, ask. If they get shifty, leave.

The things that will actually get you in trouble

Smoking in public. Treated as a public nuisance offence and it carries a fine. Balconies, private rooms and licensed premises where a practitioner administers it. Not the street, not a park, not the back of a songthaew.

Crossing a border with it. This is the serious one. Carrying cannabis into or out of Thailand is a criminal offence and a Thai prescription does not travel with you. Every year people get caught at Don Mueang and Chiang Mai airport doing something they thought was fine because they bought it legally. Legal to buy here is not legal to leave with.

Being under 20. The legal age is 20. The same rule covers anyone pregnant or breastfeeding, and pupils and students, unless a practitioner has prescribed it.

Buying from a shop with no licence on the wall. Cheaper for a reason.

What about CBD

CBD and hemp products containing under 0.2 percent THC sit outside all of this and remain legal without a prescription. Anything extracted above 0.2 percent THC is still a Category 5 narcotic, which is a different and much more serious category than flower.

Is it going to change again

Probably. A draft Cannabis and Hemp Act finished public consultation on 21 May 2026 and had not passed parliament as of late 2026. The government has said it wants it through by the end of the year, but this draft has slipped before.

When it passes, the framework on this page changes and we will update it. That is why there is a review date at the top. A page about Thai cannabis law without a date on it is close to useless, and most of them do not have one.

Where we sit

We run a licensed dispensary in Chiang Mai and we would rather explain this properly than let you work it out from a forum post written in 2023. If you want to ask something specific, message us. We answer people who are never going to buy anything from us, because a visitor who understands the rules is better for everyone working in this industry.
