How Can Foreigners Legally Get Medical Cannabis in Thailand?

A foreigner can legally get medical cannabis in Thailand by consulting a licensed Thai practitioner, in person or via approved telemedicine, obtaining a PT33 prescription, and buying only from a licensed dispensary with on-site medical supervision. A foreign medical card or prescription is not valid on its own, and you must obtain Thai documentation.

The step-by-step

First, consult a licensed Thai practitioner and describe the condition for which you are seeking cannabis treatment. Foreign medical records may support the consultation but do not replace it. Second, if a qualifying condition is identified, the practitioner issues a PT33 prescription, valid for up to 30 days. Third, present that prescription at a licensed dispensary that has a practitioner on-site. The dispensary verifies the prescription before selling.

What the prescription allows

A valid prescription lets you buy and possess cannabis within its terms. Reporting indicates patients may carry up to 30 grams with a valid prescription, including on domestic flights, though you should confirm current limits. The prescription does not permit public consumption, which remains illegal regardless of medical status. Consumption is limited to private spaces.

The telemedicine option

Approved telemedicine consultations have made the process more accessible, and many dispensaries in major tourist areas facilitate a short consultation on-site or remotely. Convenience, however, does not change the legal requirements: the consultation must be with a licensed Thai practitioner, and the prescription must be genuine.

What not to do

Do not bring cannabis from your home country, even with a valid foreign prescription. Import is prohibited and treated seriously. Do not assume a casual over-the-counter purchase is the same as a prescribed one. And do not consume in public, prescription or not.
