Is Mitragynine legal in Thailand?
- Legal status
- Neither mitragynine nor kratom is separately scheduled in Thailand: kratom was removed from Narcotics Category 5 by the Narcotics Act (No. 8) B.E. 2564 (2021), and mitragynine, the principal alkaloid of kratom, is a constituent of the now-legal plant — decriminalised together and regulated (not prohibited) under the Kratom Plant Act B.E. 2565 (2022), with sale to minors/pregnant women restricted.
- Consequences if caught
- No narcotics penalty attaches to the alkaloid; kratom is legal, though the Kratom Plant Act restricts sale to minors/pregnant women and certain preparations.
- If prescribed or medical
- No prescription requirement — kratom leaf is legal to consume; regulation is via the Kratom Plant Act, not the narcotics regime.
- Documentation
- Personal carry of the legal plant is permitted subject to the Kratom Plant Act; there is no narcotics import permit for it.
