The PT33 prescription: what it is and how to get one

Since June 2025 this one piece of paper decides whether a Thai dispensary can sell you cannabis flower. Here is what it is, who signs it and what to expect.

Who can issue a PT33

The 2025 notification names seven kinds of licensed practitioner:

1. Medical doctors
2. Dentists
3. Pharmacists
4. Thai traditional medicine practitioners
5. Applied Thai traditional medicine practitioners
6. Traditional Chinese medicine practitioners
7. Registered folk healers

They must work from a clinic or hospital, and the form is a paper document, not a screenshot.

How to get one

1. Bring ID. Thai ID card, or your passport if you are visiting. You must be 20 or older.
2. Have a consultation. In person at a clinic, at a dispensary that has a practitioner on site, or by a proper telemedicine service run by a licensed practitioner. Be ready to describe the condition you want treated.
3. Pay the consultation fee. Reported range is a few hundred to about 1,500 baht. The fee is for the assessment, so a refusal does not always mean a refund. Ask first.
4. Receive the PT33 if the practitioner agrees cannabis is appropriate. It names you, the condition, the quantity and the period, up to 30 days.
5. Take it to a licensed dispensary. They check it, sell within what it allows, and keep the form for at least a year.

What conditions qualify

The notification leaves that to the practitioner's judgement. Clinics commonly list chronic pain, insomnia, anxiety, nausea from chemotherapy, epilepsy, Parkinson's disease and appetite loss, among others. A clinic's list is a guide to what they will consider, not a legal list of approved conditions.

What the shop will ask for

• Your PT33, original paper.
• Your ID or passport, to match the name on the form.

If a shop sells you flower without asking for either, it is breaking the rules, and the risk is theirs and yours.

Watch out for

• “Cards” sold as the legal document. A membership card is not a prescription. The PT33 is the legal proof. Some services bundle a real consultation with a card; the consultation is the part that matters.
• Instant online approvals. If nobody licensed actually assesses you, the form is not compliant, whatever it looks like.
• Expired forms. After 30 days you need a new assessment.
