HB5537 would add a new section to the Michigan penal code making it unlawful to grow, synthesize, sell, offer to sell, give, import, or distribute kratom or a synthetic variant of kratom. The bill defines kratom broadly to include products made from the Mitragyna speciosa plant and its extracts, and it specifically identifies synthetic forms such as 7-hydroxymitragynine (7-OH). It also creates a limited exception for kratom products that have been approved by the U.S. Food and Drug Administration as a drug product, dietary supplement, or food additive in conventional food, but that exception does not extend to synthetic variants.
The bill establishes misdemeanor penalties that escalate based on repeat offenses and sales to minors. A first violation is punishable by up to 90 days in jail and/or a $5,000 fine; a subsequent violation can bring up to 180 days and/or a $10,000 fine; and selling or distributing kratom to someone under 18 carries up to one year in jail and/or a $10,000 fine, with higher fines for repeat offenses involving minors. The act would take effect 90 days after enactment.
In terms of state law, HB5537 would expand Michigan’s controlled-substances-related criminal prohibitions by creating a specific offense for kratom and synthetic kratom products within the penal code. It would directly affect manufacturers, retailers, distributors, importers, and individuals involved in kratom commerce, while leaving room for FDA-approved kratom products under the narrow statutory exception. The bill would also give law enforcement and prosecutors a new misdemeanor charge to use against kratom-related activity.
The available voting history suggests the bill was controversial but had enough support to pass the House on third reading with immediate effect, 56-48. That margin indicates a divided chamber and a generally mixed sentiment, with supporters likely viewing the bill as a public-safety and youth-protection measure and opponents likely concerned about overcriminalization or the impact on lawful kratom sales and use. No committee transcript is available here, so the specific arguments were not recorded in the provided materials.
The main point of contention is the scope of the ban: the bill prohibits not only synthetic kratom but also natural kratom products and their distribution, subject only to the FDA approval exception. That broad approach could affect consumers, retailers, and vendors who use kratom as a supplement or herbal product, while supporters may argue that the bill is needed to address health risks, unregulated products, and sales to minors.
HB5537 would amend the Michigan penal code by adding a new misdemeanor offense targeting kratom and synthetic kratom, thereby creating new criminal liability for production, sale, importation, gifting, and distribution of these products. It would affect individuals and businesses involved in the kratom market, while carving out a narrow exception for FDA-approved kratom products and imposing enhanced penalties for repeat violations and sales to minors.
The bill appears to have generated mixed to negative sentiment overall, as reflected by the close House vote of 56-48 on immediate effect. Supporters likely favored the measure as a public-health and youth-protection restriction, while opponents likely viewed it as an overly broad criminal prohibition on a product that is sold in legal retail channels. The absence of committee transcripts limits more detailed insight into the debate.
The central controversy is whether Michigan should broadly criminalize kratom and synthetic kratom or regulate it more narrowly. Opponents are likely to object to the bill’s sweeping ban on growing, selling, importing, and distributing kratom, especially for adults and lawful retailers, while supporters are likely focused on concerns about safety, unregulated products, and access by minors. The FDA-approved-product exception may also be a point of debate because it is narrow and does not apply to synthetic variants.
