Legislative History

Thailand briefly decriminalized recreational cannabis in 2022, removing it from the narcotics list and allowing unregulated sales and personal cultivation. However, following public health concerns and a change in government policy, recreational use was re-criminalized in 2024–2025, restoring prohibitions on non-medical possession, sales, and public consumption while maintaining a regulated medical framework for prescription access.

Law Enforcement

At the time, imports, exports and possession were described as requiring permission from the Ministry of Public Health and approval by the Office of the Narcotics Control Board. People caught on Ko Chang reportedly paid at least ฿3,000, described variously as a fine or a bribe.
