Thailand has one of the most fascinating cannabis histories in Southeast Asia. From traditional medicine to prohibition, and from decriminalization to strict medical regulation — the journey of the “green goddess” in the Land of Smiles is anything but simple.
A Brief History
Cannabis has been part of Thai culture for centuries. Traditional Thai medicine used cannabis leaves to relieve fatigue and improve appetite. However, in 1935, cannabis was classified as a narcotic, beginning a long period of prohibition.
Fast forward to 2018 — Thailand became the first Southeast Asian country to legalize medical cannabis. Then in 2022, decriminalization opened the door for a “green rush,” with thousands of dispensaries opening across the country.
The 2025 Regulatory Shift
As of June 2025, Thailand reclassified cannabis flowers as a controlled herb . What does this mean?
- Medical prescription is now required for cannabis flower
- Recreational use is not permitted
- Public smoking remains prohibited
- Online sales and delivery are banned
Today’s Legal Framework
Under the current regulations:
- Only patients with valid prescriptions can purchase cannabis flower
- Prescriptions must be issued by Thai-licensed medical professionals
- Sales are limited to a 30-day supply per prescription
- Licensed dispensaries must verify every prescription and maintain detailed records
Where Thai Cannabis Culture Is Headed
Thailand is positioning cannabis as a medical and wellness tool — not a recreational product. The government has made clear that Thailand should not be seen as a destination for recreational cannabis use.
At Green Goddess, we fully support this approach. Our 6 licensed locations — Patong, Kata 1, Kata 2, Karon, Old Town, and Bang Tao — operate in full compliance with Thai law.
