Thailand's cannabis rules for visitors (2026)

What the law allows, what it does not, and why.

As of 2026 | Last reviewed July 2026

The short answer

As of 2026, cannabis is legal in Thailand only within a medical framework. Cannabis flower is a controlled herb, sold only by licensed dispensaries and only to customers aged 20 or older who hold a prescription on form PT33 issued by a licensed Thai practitioner. Every purchase happens in person, because Thai law prohibits online sales and delivery. Smoking cannabis in public places carries penalties, and taking cannabis across international borders is a serious offense.

Where things stand in 2026

Thailand's cannabis rules changed in 2025, and they are enforced. Cannabis flower is now classified as a controlled herb under the Ministry of Public Health's controlled-herb regulations, and since 2025 it may only be dispensed to holders of a prescription on form PT33 from a licensed Thai practitioner.

For a visitor, the practical picture is simple. Buying cannabis is legal when you follow the medical route: a consultation, a PT33 prescription, and an in-person purchase at a licensed dispensary, age 20 and over. Outside that route there is no legal way to buy cannabis flower in Thailand, and recreational sale is not permitted.

Your questions, answered

Is cannabis legal in Thailand in 2026?

Yes, but only within a medical framework. Thailand classifies cannabis flower as a controlled herb under the Ministry of Public Health's regulations, which means it can be sold only by licensed dispensaries and only against a practitioner's prescription. There is no legal recreational market, and the rules are actively enforced.

Can tourists buy cannabis legally?

Yes. The medical route is open to visitors, and the steps are the same ones residents follow: consult a licensed Thai practitioner, receive a prescription on form PT33 if the practitioner considers it appropriate, then buy in person at a licensed dispensary. At the counter, your passport works as your ID.

Do I need a prescription, and how do I get one?

Yes. Since 2025, cannabis flower may only be dispensed to holders of a PT33 prescription, which can be issued by a doctor, a Thai traditional medicine practitioner, or another practitioner authorized by law. Clinics across Bangkok offer same-day consultations, a prescription is valid for up to 30 days, and the form states the quantity you may receive and the duration of use. If you do not have a prescription yet, our staff can point you toward partner clinics close to the shop.

What is the age limit?

You must be 20 years of age or older. Thai law also prohibits sales to pregnant women and to breastfeeding women, and ID is checked on every purchase. For visitors, that means bringing your passport each time.

Can I order cannabis online or have it delivered?

No. Thai law prohibits both online sales of cannabis flower and delivery, so there is no legal webshop, courier service, or vending machine. Every legal purchase is made face to face at a licensed dispensary, with your prescription and your passport.

Where am I allowed to smoke or consume?

Only in private. Thai law treats smoking cannabis in public places as a public nuisance, and it carries penalties. Consumption is not allowed on our premises either, so plan to use what you buy in private, following the guidance your practitioner gives you.

Can I take cannabis out of Thailand?

No, never. Carrying cannabis across an international border is a serious offense, even if cannabis is legal where you are headed. Use up or dispose of anything you have bought before you leave the country.

Where can I buy legally in Bangkok?

Only at licensed dispensaries, and only with your PT33 prescription in hand. The Weed Shop is a licensed controlled-herb dispensary at 94/1 Srinagarindra Road, Nong Bon, Prawet, Bangkok 10250, Thailand, a short walk from Paradise Park shopping mall and near the MRT Yellow Line. The shop is open daily from noon to midnight, and a licensed practitioner is on site during opening hours.
