Chamber Passed·3/18/26

Michigan HB5537 prohibits the production, sale, and offer to sell kratom and its synthetic variants.

Michigan HB5537 amends the state's controlled substances law to add a new section prohibiting the growth, synthesis, sale, or offer to sell kratom and its synthetic variants. The bill defines "kratom" as any product containing any part of the Mitragyna speciosa plant, and "synthetic variant of kratom" as any synthetic form of kratom. Violators face misdemeanor charges with penalties including imprisonment and fines, with harsher penalties for selling to minors and repeat offenders. The law would take effect 90 days after being enacted.
