Thailand Marijuana Laws

As recorded December 15, 2025 · not verified as current law.

Cannabis laws in Thailand follow Thailand’s national law. Local cities generally do not set separate marijuana rules, so penalties are determined at the jurisdiction level.

Recreational use of cannabis is illegal. Medical cannabis is permitted for specific conditions with a prescription. Unauthorized possession or use can result in legal penalties.

Quick facts

  • Recreational: Illegal
  • Medical: Available with prescription for limited conditions
  • Possession: Illegal without medical authorization
  • Buying/Selling: Restricted to licensed medical channels
  • Tourists: Subject to the same laws with no exemptions

Practical guidance

Avoid cross-border transport of cannabis products. Do not assume informal tolerance equals legality.

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.
