Legal Status of Cannabis in Thailand

Cannabis has undergone significant legal changes in Thailand over the past few years. Initially decriminalised in June 2022, the country became the first in Asia to legalise cannabis for recreational use. However, in 2025, the Thai government reversed this policy, reclassifying cannabis as a controlled substance and restricting its use to medical purposes only.

Possession and Public Use

As of June 2025, possession of cannabis is illegal unless one holds a valid medical prescription. Public consumption is prohibited and can result in fines or other legal consequences. The government has implemented these measures to curb misuse and protect public health.

Medical Cannabis

Medical cannabis is legal in Thailand but strictly regulated. Only individuals with a doctor's prescription can legally obtain cannabis for medical use. The government has established a framework to ensure that cannabis is used safely and appropriately for medical purposes.

Cultivation

Cultivation of cannabis is permitted for medical use but requires proper registration and adherence to government regulations. Individuals interested in cultivating cannabis for medical purposes must obtain the necessary permits and comply with all legal requirements.

Driving Under the Influence

Driving under the influence of cannabis is illegal in Thailand. Law enforcement agencies are authorised to conduct roadside sobriety tests, and individuals found impaired by cannabis may face penalties, including fines, licence suspension, or imprisonment. The legal limit for THC in the blood is not clearly defined, but any detectable amount can lead to legal consequences.

Tourists and Cannabis Laws

Tourists visiting Thailand should be aware that recreational cannabis use is illegal. Possession, use, or trafficking of cannabis can lead to arrest and prosecution. Medical cannabis laws apply only to residents registered with the state programme. Visitors are advised to comply fully with local laws to avoid legal issues during their stay.

Public Perception and Cultural Context

Cannabis use in Thailand remains a topic of debate. Public opinion is gradually shifting, with increasing support for medical cannabis legalisation. However, recreational use continues to face strong legal and social opposition. The state's approach to cannabis is influenced by political, cultural, and public health considerations.

Recent Developments and Future Outlook

The Thai government has recently moved to re-criminalise cannabis for recreational use, citing concerns over public health and misuse. While the legal framework for medical cannabis remains in place, the future of cannabis legislation in Thailand is uncertain, with ongoing discussions about potential reforms.

In Summary

Cannabis is illegal for recreational use in Thailand, with possession and public consumption subject to penalties. Medical cannabis is legal and regulated, available to qualifying patients through a state programme. Cultivation for medical use is permitted under strict regulations, and driving under the influence is illegal. Tourists should adhere to local laws to avoid legal issues. While public opinion is shifting, significant legislative changes regarding cannabis legalisation have not yet occurred in the country.
