- The excise tax is not applied to medical marijuana.
Revenue Allocation
Tax revenues are distributed to:

14. Future Outlook
Looking forward, Michigan is expected to:
- Expand licensing options for small businesses and cooperatives.
- Update zoning laws to increase access in underserved areas.
- Improve social equity outreach and effectiveness.
- Monitor and adapt to potential changes at the federal level, especially concerning rescheduling or banking reforms.
15. Conclusion
Michigan’s approach to marijuana regulation in 2025 is among the most comprehensive in the United States. Legal access for both recreational and medical users is well-defined, supported by a robust licensing system and a strong commitment to public health and social equity. Although challenges remain—particularly concerning federal law and market enforcement—the state continues to lead with a forward-thinking, citizen-focused policy model.
