Narcotics & Drug Law Overview: Introduction to Thai Law
Comprehensive introduction to narcotics & drug law principles, historical development, and key legislation governing narcotics & drug law matters in Thailand.
Introduction to Narcotics & Drug Law
Thailand's drug laws are primarily governed by the Narcotics Code B.E. 2564 (2021, consolidating the former Narcotics Act B.E. 2522 (1979)) and the Psychotropic Substances Act B.E. 2518 (1975). Cannabis was removed from the Category 5 narcotics list by Ministry of Public Health notification effective 9 June 2022, making Thailand the first Asian country to decriminalize it. Note that a standalone Cannabis and Hemp Act has been through repeated drafts but has not been enacted — cannabis is instead regulated through ministerial notifications, which have tightened materially since 2024 toward medical and health use only. Verify the current instrument before relying on it. Drug offences remain among the most severely punished in Thailand, with Category 1 substances (heroin, methamphetamine, MDMA) carrying penalties up to life imprisonment or death. The Narcotics Control Board oversees drug policy and enforcement.
