Now that HB5537 has passed the house, it is expected to cross over to the senate in it’s entirety. The best changes of success at defeating this now is by reaching out, calling and emailing your state senator. It is not expect to come up until after spring break, which would be early April. That could change! Be sure to monitor your state senate agenda calendar. As always, if you chose to email more than just your state senator, make sure you send individual emails, not in mass.

HB4969 (KCPA)
If passed, the bill would introduce several strict requirements for businesses and safety standards for consumers:  

  • Age Restriction: It would prohibit the sale of kratom products to anyone under 21 years of age.  
  • Licensing: Starting January 1, 2027, any person or business manufacturing or selling kratom (including online sales to Michigan residents) would be required to obtain a license from the Department of Licensing and Regulatory Affairs (LARA).
  • Safety & Lab Testing: Manufacturers would be required to have raw materials tested by an independent third-party laboratory. This is to ensure products are not adulterated with dangerous substances or synthetic alkaloids (like synthetic 7-hydroxymitragynine).  
  • Labeling Requirements: Products must clearly state:
    • Alkaloid content (specifically mitragynine and 7-OH).  
    • A warning that kratom is an unapproved dietary ingredient and may be habit-forming.  
    • Instructions for recommended serving sizes.  
  • Potency Limits: The bill specifically targets “highly potent” versions and would limit 7-hydroxymitragynine (7-OH) levels to no more than 2% of the total alkaloid content.  

Penalties for Violations
The bill establishes civil fines for non-compliance:  

  • First offense: Up to $1,000.  
  • Subsequent offenses: Up to $5,000.  
  • Selling to a minor or operating without a license could also result in license suspension or revocation.  

Current Status
The bill was reported out of the House Regulatory Reform Committee on November 13, 2025, with a recommendation for passage. It is currently awaiting further votes in the House.

While HB 4969 focuses on regulation, you should be aware of HB 5537, a separate bill introduced in February 2026 that seeks a much stricter prohibition of certain kratom products.
