Since Thailand’s historic decriminalization of cannabis in 2022, the legal status of THC—the psychoactive compound in cannabis—has been a hot topic for locals, expats, and tourists alike. So, is THC legal in Thailand in 2025? The answer is partially—under tight restrictions.
This guide breaks down what’s allowed, what isn’t, and how you can safely and legally access THC in Thailand today.
Understanding THC in Thai Law
As of the time we’re writing this article (May 2025), THC is legal in Thailand, but only in certain forms and under regulated conditions:
- THC content in cannabis extracts must be below 0.2% to be legally sold or marketed.
- Cannabis flower (containing THC) can be purchased and used legally by adults aged 20 and above, but only from licensed dispensaries.
- Recreational use is tolerated but not fully legalized—and public consumption (e.g., smoking in the street or on beaches) remains banned and punishable with fines.
- Medical use of higher-THC cannabis is permitted under prescription and Thai FDA oversight.
In short: you can buy and use THC-containing cannabis in Thailand, but only through approved channels and within legal guidelines.
Buying THC Products in Thailand: What’s Allowed
Licensed cannabis dispensaries across Thailand now legally offer a range of THC products, including:
- Dried cannabis flower (buds)
- Pre-rolls
- THC-rich cannabis strains
- Low-THC oils and edibles (<0.2%)
- Medical cannabis (higher THC) via prescription
THC edibles and extracts must contain less than 0.2% THC by weight unless specifically prescribed. Dispensaries are required to label THC content clearly and verify the age of all buyers (must be 20+).
🚫 Where THC Use Is Not Legal
Despite decriminalization, certain behaviors and contexts remain illegal:
- Public consumption of THC (smoking/vaping) is illegal under the Public Health Act.
- Possessing or selling cannabis products to minors is strictly prohibited.

Breaking these laws can result in fines, police questioning, or more serious charges, especially for non-residents.
