Thailand operates one of the most accessible medical cannabis programs in Asia. Since decriminalizing cannabis in June 2022 and transitioning to a medical-only framework in June 2025, the country has built a comprehensive system connecting patients with licensed practitioners, government-subsidized products, and a nationwide network of clinics and dispensaries.
Whether you are a Thai national exploring cannabis as a treatment option, a tourist seeking legal access, or an expat managing a chronic condition, this guide covers everything you need to know about accessing medical cannabis in Thailand.
How Thailand’s Medical Cannabis System Works
The Medical Framework (Since June 2025)
Thailand’s cannabis system operates under a medical framework following the June 2025 reclassification of cannabis flower as a “controlled herb.” For full legal details, see our Cannabis Laws Thailand 2026 guide.
The core principle is simple:
- See a practitioner → Get evaluated for a qualifying condition
- Receive a PT 33 prescription → The official cannabis prescription form
- Purchase products → From a licensed dispensary or hospital pharmacy
- Use as directed → Follow your practitioner’s dosage guidance
This system ensures medical oversight while making cannabis accessible to those who need it.
Who Can Prescribe Medical Cannabis
Eight types of licensed practitioners can issue PT 33 prescriptions in Thailand:
| Practitioner Type | Thai Title | Common Setting |
|---|---|---|
| Physicians | แพทย์ | Hospitals, private clinics |
| Dentists | ทันตแพทย์ | Dental clinics |
| Pharmacists | เภสัชกร | Pharmacies, dispensaries |
