What It Is

A PT 33 is the prescription document used to record legal medical cannabis access in Thailand. In plain language, it is the formal paperwork showing that access has been authorised through the proper medical channel rather than informally. It is the record that places your access inside the regulated framework.

Who Can Issue It

A PT 33 is issued by a licensed practitioner, not by the patient. At Treehouse it is issued through the licensed clinic after a consultation and an individual evaluation. The involvement of a licensed professional is what gives the document its standing within the regulated system.

Why It Is Required

Because medical cannabis access in Thailand is built around documentation and oversight, the prescription is the required record of legal access. Without a practitioner-issued prescription, access sits outside the regulated medical framework. The PT 33 is what keeps the process accountable and traceable.

A prescription is a formal record, so it carries identifying details and is kept on file by the licensed clinic. Here is how that works in plain terms.

01 Identifying Details The prescription identifies the patient and the issuing licensed practitioner. This is standard for a formal medical document and supports clear, accountable recordkeeping.
02 Issued After Evaluation A PT 33 follows a consultation and an individual evaluation by a licensed practitioner. It is the outcome of a clinical decision, not an automatic or self-service form.
03 Defined Validity A prescription applies for a defined period set by the practitioner. When that period ends, or if your situation changes, a follow-up consultation is the route to a renewed evaluation — the practitioner decides what is appropriate.
04 Kept On File Prescriptions are documented and retained by the licensed clinic in line with Thai regulations. Proper recordkeeping is part of how the regulated medical framework is designed to operate.

A PT 33 is issued by a licensed practitioner. At Treehouse, this is done through the licensed clinic following a consultation. It is not something a patient can self-issue or obtain without a practitioner evaluation.

Yes. The PT 33 prescription is the document that records legal medical access. Without a practitioner-issued prescription, access does not sit within the regulated medical framework.

Prescriptions are documented and recorded by the licensed clinic and practitioner in line with Thai regulations. The prescription identifies the patient and the issuing practitioner, supporting traceability and proper recordkeeping.
