Medical cannabis in Thailand

How to get a medical cannabis prescription in Thailand

Cannabis is legal in Thailand for medical use only, and every purchase needs a valid prescription on the Thai form ภ.ท.33, written "PT 33" in English. Here is what the prescription is, who can get one, and how the visit works, whether you live here or you are visiting.

This page is general information about the Thai medical-cannabis framework, not medical advice. Whether cannabis is right for you is a decision for the licensed practitioner who assesses you.

What the ภ.ท.33 (PT 33) prescription is

Cannabis flower is a controlled herb under Thai Ministry of Public Health rules. It is legal for medical use only, and to buy it you need a valid medical-cannabis prescription on form ภ.ท.33. A licensed practitioner issues the prescription, and it is valid for up to a 30-day supply.

Who can get one, visitors included

Anyone aged 20 or older can be assessed, visitors from outside Thailand included. The decision rests entirely on the practitioner's medical assessment during your consultation. Prescriptions and medical cards from other countries are not valid in Thailand, so you are assessed here. Carrying cannabis across the border in either direction is prohibited.
