HB 5105 Michigan House · 2025-2026 Regular Session

Crimes: penalties; penalties regarding certain crimes involving marihuana; modify. Amends sec. 7401 of 1978 PA 368 (MCL 333.7401). TIE BAR WITH: HB 5107'25

HB 5105 modifies Michigan's sentencing rules for marijuana possession offenses under the Public Health Code. It lowers penalties for most possession amounts, reclassifying some as misdemeanors (e.g., 1-5 kilograms or 50-100 plants becomes a misdemeanor punishable by up to 1 year in jail or a $20,000 fine). For larger amounts, it reduces maximum prison terms (e.g., 45+ kilograms now carries a max 10-year felony instead of 15 years). The bill directly affects individuals convicted of marijuana offenses under current law, altering sentencing based on quantity. It is pending in committee after introduction on October 22, 2025.

MINOR

The bill was formally amended to become a substitute version, adding a specific prohibition against practitioners dispensing controlled substances for non-therapeutic purposes. The most significant substantive change involves the penalties for marijuana possession and distribution, which were restructured to include new sentencing tiers for smaller quantities of marijuana concentrate and adjusted thresholds for plant counts and weight limits.

Scope change

The bill's scope regarding practitioner conduct was expanded to explicitly ban non-therapeutic use, while the scope of criminal penalties for marijuana offenses was broadened and reorganized to cover a wider range of quantity thresholds.

REQUIREMENT

Added a new requirement prohibiting licensed practitioners from dispensing controlled substances for purposes other than legitimate therapeutic or scientific use.

ENFORCEMENT

Modified the enforcement penalties for marijuana offenses by adding new sentencing tiers for smaller amounts of marijuana concentrate and adjusting the weight and plant count thresholds for felony and misdemeanor classifications.

TIMELINE

Modified the effective date clause by removing the specific reference to a companion bill number, changing the condition for when the act takes effect.
