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.
