Last updated: May 2026

Possession Limits

• In public: 2.5oz. At home: up to 10oz.
• Concentrates: 15g. Edibles: 10mg/serving, 100mg/package.
• Medical: 2.5oz at a time, 10oz monthly.

Home Cultivation

Up to 12 plants per HOUSEHOLD (not per person). Must be locked, enclosed, invisible from public. Medical caregivers: up to 12 plants per patient.

DUI / Impairment

Technically zero tolerance (any detectable THC). However, Michigan Supreme Court ruled the state must demonstrate actual impairment. Mere presence of THC is insufficient for conviction.

New Taxes (2026)

24% wholesale excise tax on recreational transfers to retailers (January 2026), on top of existing 10% retail excise tax and standard sales tax.

What Most People Get Wrong

People assume the 12-plant home grow limit is per person. It is per HOUSEHOLD. Two adults living together still share the 12-plant cap. And plants must be locked and enclosed. Growing openly in a backyard is illegal regardless of plant count.
