Can tourists buy cannabis in Thailand?

The open-counter days of 2022 to mid-2025 are over. You can still buy legally as a visitor, but there is a step in between that most travel blogs skip.

The three steps

1. Get assessed. A clinic, a dispensary with a practitioner on site, or a proper telemedicine service. Passport required. Reported fee: a few hundred to about 1,500 baht. Approval is the practitioner's decision.
2. Hold the PT33. Paper form, your name, up to 30 days of supply, single use. Read how the PT33 works.
3. Buy in person. The shop checks the form and your passport and keeps the form. No online orders, no delivery.

What gets visitors in trouble

• Buying from a shop that does not ask for a prescription. The sale is illegal and the shop may be raided.
• Smoking in public: streets, beaches, bars, hotel balconies where it bothers others.
• Carrying it to the airport. Border checks treat it as a narcotic offence.
• Carrying more than your prescription covers.
• Assuming a foreign card, letter or app makes you exempt. It does not.

What has not changed

• CBD products at or under 0.2% THC are reported to need no prescription.
• You must be 20. Shops and clinics check.
• Licensed dispensaries still operate across the country. High Time Maps lists them by province with photos and hours.

Before you fly

Read the current cannabis law in Thailand so nothing at the counter surprises you. If a clinic or shop tells you something different from this page, they may be right and we may be behind. The rules moved in 2022 and again in 2025.
