Is weed legal in Thailand?

Is weed legal in 2026?

Only inside a medical system: a consultation, a Thai prescription, and a licensed shop.

Since late June 2025, cannabis flower has been a controlled herb, and only medical use with a valid Thai prescription, the PT 33, is allowed.

It hasn't gone back on the narcotics list: it sits in its own category, with its own rules and penalties.

A prescription or cannabis card from home doesn't count in Thailand. Only a PT 33 from a Thai-licensed practitioner does.

What changed, and when

The rules have changed several times since 2018, so much of what's online still describes 2022.

The Thai government says the new rules took effect on 23 June 2025, and banned sales online, from vending machines and in places like temples, parks and dormitories.

So if a guide gives you a plain yes with no mention of a prescription, it's out of date. Ask Tanner before you trust an old guide.

Can tourists buy it?

Can tourists buy weed in Thailand? Only with a prescription issued in Thailand by a licensed practitioner in Thai traditional medicine, Chinese medicine or dentistry, for no more than a 30-day supply, the Thai government says (27 June 2025; checked November 2026).

You buy from a licensed shop, nowhere else: no online sales, no vending machines and no advertising, under the Ministry of Public Health's notification in the Royal Gazette of 25 June 2025.

A PT 33 covers buying and holding cannabis inside Thailand only.

An open shop is not proof that a sale is legal: the government warns that shops selling to walk-in customers may be breaking the law. Ask Tanner, and he keeps your plans well clear of the grey areas.

Can you smoke it on the street?

No: tourists may not use cannabis without a Thai prescription, and even with one, smoke on a street, a beach or in a bar can count as a public nuisance.

Smoke or smell that bothers other people is a nuisance under the Public Health Act: ignore an officer's order to stop, and it can mean up to 3 months in prison or a ฿25,000 fine.

That covers Khao San Road, Bangla Road and Walking Street too, and many hotels ban it in rooms, with a fine or a cleaning fee.

Ask Tanner for a villa with house rules you know before you book.

What happens if you're caught

If you're caught buying or holding weed in Thailand without a prescription, you face a controlled-herb offence, with a fine and possible prison time.

Buying or selling outside the prescription system breaks the controlled-herb rules, and the Thai government warns that shops selling to walk-in customers for smoking may be operating outside the law.

The easy plan is to skip it: our host keeps the night on the clubs, the table and the car. Ask Tanner to put a host with your group for the night.

CBD, edibles and vapes

CBD products are still sold, but anything with THC is tightly controlled, so check the label and the shop's licence.

Edibles, oils and gummies with real THC need a prescription.

Vapes are a separate law. Importing e-cigarettes can mean up to 10 years in prison, and holding smuggled vapes up to 5 years or a fine of four times their value, under the Customs Act, the Thai government says.

Check the label before you buy anything, and leave the vape at home. Ask Tanner if you're unsure about anything in your bag.

Can you bring it in?

No, you can't bring cannabis into Thailand, even with a prescription from home, and taking it out is illegal too, including products bought legally here.

Taking any part of the plant, or its seeds, into or out of Thailand is not permitted, the Ministry of Public Health's tourist guide says (checked November 2026).

Some countries still treat cannabis as a serious narcotic, so the rules at home matter too.

The simple rule: nothing in your bag on the way in, and nothing on the way out. Ask Tanner to have the car waiting at arrivals.

The other drugs

For everything else, Thailand's drug laws are hard: possessing even a small amount of a Schedule I, II or V narcotic for personal use can mean up to 2 years in prison, a fine of up to ฿40,000, or both, the Office of the Narcotics Control Board says.

Trafficking carries far heavier sentences, so the rule for a group is simple.

For a group: no drugs, no exceptions, and no favours for strangers. Ask Tanner and a host stays with the group all night.

Is Thailand 420 friendly?

No, Thailand is no longer 420 friendly: the same rules apply in Bangkok, Phuket, Pattaya and Koh Samui, and the open market of 2022 is over.

Is it legal to smoke weed in Phuket? No more than anywhere else: the same rules apply on Bangla Road, on Walking Street and at the Full Moon Party.

Leave it out; the clubs and the beach are the trip. Tanner's pick for the big night: a VIP table at the club and the car waiting outside. Ask Tanner for the table.

What's coming next

Next up is a Cannabis and Hemp Act, which would control cannabis from the farm to the shop, with higher penalties.

Until a new act is passed, the June 2025 rules on this page are the ones that apply.

Check this page in the week before you fly; we review it whenever the rules change. Ask Tanner what's new since.

Plan a trip that leaves it out

Plan the trip without it: a yacht day and a pool party don't need it.

A driver stays with the group all night, so nobody wanders off at 3am.
