From June 23, 2025, cannabis flower is a controlled substance in Thailand. Tourists must avoid using or purchasing it without a Thai prescription. Strict regulations target misuse and unlicensed sales.
Authorities have implemented these measures to ensure public safety and maintain order. Violations can lead to severe penalties, including fines or imprisonment. Tourists are encouraged to familiarize themselves with local laws and seek legal products only through authorized channels. Additionally, educational campaigns are being launched to inform both locals and visitors about the legal implications and health aspects of cannabis use.
Cannabis as a Controlled Substance
As of June 23, 2025, the Tourism Authority of Thailand (TAT) informs visitors that cannabis flower is now a controlled substance in Thailand. This change follows a new regulation issued by the Ministry of Public Health under the Thai Traditional Medicine Wisdom Protection and Promotion Act B.E. 2552 (2009). This regulation replaces the previous directive from November 2022. While cannabis was removed from the narcotics list in 2022, it was intended solely for medical, research, and health-related uses.
Stricter Regulations for Tourists
The 2025 regulation enforces stricter rules nationwide on the use, sale, and possession of cannabis flower, targeting its potential misuse. Tourists are prohibited from engaging with cannabis flowers unless prescribed by a licensed Thai medical professional. Even then, the supply is limited to a 30-day medical necessity. Unlicensed cannabis shops, especially those targeting tourists, may operate illegally, with authorities actively monitoring sales and cracking down on violations.
Prohibited Sales and Responsible Tourism
Cannabis products cannot be legally sold online, via vending machines, or advertised. Additionally, sales are banned in public spaces like temples, parks, and amusement venues. TAT urges visitors to avoid engaging with cannabis unless verified by licensed providers and warns that seemingly tolerated practices were never legally approved. Staying informed and abiding by these regulations ensures a respectful and safe visit.
