Thailand's approach to cannabis regulation has moved quickly
from broad access to a medical, prescription‑only system. The
latest government regulation classifies the cannabis flower as a
controlled herb under the Thai Traditional Medicine Wisdom Act.
The latest rules ban advertising and recreational sales, allow
sales only to patients with prescriptions (up to 30 days), and
require flowers to come from GACP‑certified (Good
Agricultural and Collection Practices) farms. More importantly,
cannabis dispensaries can only sell to patients presenting valid
prescriptions issued by one of seven professions—medical
doctors, Thai traditional practitioners, applied Thai traditional
practitioners, traditional Chinese medicine practitioners,
pharmacists, dentists, and folk healers—consistent with
approved clinical indications. Noncompliance risks license
suspension or revocation, and criminal penalties of up to one
year's imprisonment or a THB 20,000 fine.
