PT 33 Prescription Required
Buying flower here requires a PT 33 prescription. That has been the rule since 26 June 2025, when cannabis flower was reclassified as a controlled herb for medical use only. Prescriptions come from DTAM-certified doctors, Thai traditional medicine practitioners and a few other licensed professions, and each one covers at most 30 days’ supply. CBD products under 0.2% THC are the exception and need no prescription. For clinics in and around Udon Thani, see our clinic directory and the PT 33 guide.
