This bill would prohibit the growing, manufacturing, and sale of kratom, a substance made from the leaves of the Mitragyna speciosa plant, and any of its synthetic versions in Michigan. If someone is caught violating this law, they could be charged with a misdemeanor, facing up to 90 days in jail and a $5,000 fine for a first offense. Penalties increase for repeat offenses or for selling to minors, with up to a year in jail and higher fines if the buyer is under 18. The law would go into effect 90 days after it is enacted, requiring stores and suppliers to quickly remove kratom products from their shelves.
