Thailand cannabis regulations changed dramatically in 2025. The government now requires medical prescriptions for all cannabis use and forbids smoking in most commercial cannabis establishments. After the 2022 decriminalization, cannabis usage rose sharply. In response, authorities introduced tighter rules to reinforce medical oversight and prevent misuse.

Authorities also require license holders to track and report cannabis quantities, sources, and purposes. This proactive monitoring helps prevent illegal distribution and supports regulatory compliance.
