House Bill 5107 – The MRTMA Shuffle

Michigan House Bill 5105 proposes new marijuana penalties and possession limits to combat illicit cannabis operations.

Michigan’s Cannabis Regulation Challenges

Since Michigan legalized recreational marijuana in 2018 under the Michigan Regulation and Taxation of Marihuana Act (MRTMA), the state has faced ongoing challenges with illegal grow operations and unlicensed distribution. The Cannabis Regulatory Agency (CRA) has struggled to enforce limits on personal possession and cultivation, especially when large-scale operations disguise themselves as personal use.

To address these concerns, lawmakers introduced House Bill 5107 on October 22, 2025, sponsored by Rep. Mike Hoadley and co-sponsored by several others. The bill aims to amend Sections 5 and 15 of MRTMA (MCL 333.27955 and MCL 333.27965) to redefine the allowable amounts of marijuana for personal use and possession

What HB 5107 Proposes

HB 5107 modifies the legal thresholds for marijuana possession and cultivation. The bill proposes reducing the number of plants and the amount of usable marijuana individuals can possess without triggering criminal penalties. It also clarifies the distinction between personal use and commercial-scale activity.

The bill is tie-barred to HB 5105, meaning both must be passed together. HB 5105 updates the penalties for marijuana-related offenses, while HB 5107 sets the legal possession limits. This ensures that enforcement is consistent and that penalties are applied fairly based on updated thresholds.

Don’t worry the bill is tie-barred to House Bill 5105

How HB 5105 and HB 5107 Work Together

• HB 5105 amends the Michigan Public Health Code (MCL 333.7401) to redefine criminal penalties for marijuana-related offenses. It introduces tiered penalties based on the amount of marijuana or concentrate possessed or manufactured.
• HB 5107 amends the Michigan Regulation and Taxation of Marihuana Act (MCL 333.27955 and MCL 333.27965) to modify the allowable amounts of marijuana for personal use and possession.

Because HB 5105 sets penalties and HB 5107 sets the legal possession limits, the two bills are interdependent. For example, if HB 5107 changes the legal threshold for personal possession, HB 5105 must reflect those changes in its penalty structure. The tie-bar ensures that enforcement and legal standards remain aligned.

What Does “Tie-Barred” Mean?

In Michigan legislative terms, a tie-bar means that one bill is legally connected to another. If two bills are tie-barred, they must both be passed for either to take effect. This ensures that related legal changes are implemented together, maintaining consistency across statutes.
