THE USEFUL PART
Keep these in your head.
- Adults 21+ may possess cannabis under the Michigan Regulation and Taxation of Marihuana Act.
- Up to 2.5 ounces in public, with no more than 15 grams of concentrate; up to 10 ounces may be kept at home, with amounts over 2.5 ounces secured.
- Up to 12 plants per household, not visible from public places and secured.
The status, in one screen
Adults 21+ may possess cannabis under the Michigan Regulation and Taxation of Marihuana Act.
What this label does—and does not—mean
Adults 21+ have legal possession under state law; limits, public-use rules, local rules, and retail availability still vary. It does not answer public use, driving, employment, housing, federal property, tribal jurisdiction, or a city's business rules.
Possession and use
Up to 2.5 ounces in public, with no more than 15 grams of concentrate; up to 10 ounces may be kept at home, with amounts over 2.5 ounces secured.
- Public consumption can remain prohibited even when possession is legal.
- Never drive, bike in traffic, boat, or operate machinery while impaired.
- Keep products in their original package and outside the passenger area when transporting within the state.
- Local ordinances and property policies can add restrictions without changing statewide status.
Home cultivation
Up to 12 plants per household, not visible from public places and secured.
Plant counts are only the first layer. Lease terms, owner permission, visibility, locked-area rules, nuisance law, processing limits, and possession of harvested cannabis can each change the practical answer.
Medical access
Medical and licensed adult-use markets.
A recommendation, registry card, out-of-state card, or diagnosis does not create identical rights everywhere. Confirm patient eligibility, reciprocity, purchase limits, approved forms, renewal rules, and caregiver rights with the official program.
Buying and retail status
Licensed adult-use retail; municipalities may opt out.
Use the state regulator's live license lookup where available. A website, delivery claim, hemp label, social-media account, or storefront sign is not proof of a marijuana license.
What you need to buy legally
No recreational card required
There is no state recreational-consumer card application. Adults 21+ may use a valid, unexpired government-issued photo ID at a licensed adult-use retailer where sales are operational.
State medical card required
How to qualify: Meet with an eligible practitioner, obtain the required certification, then complete the official state patient application and wait for approval.
Adults 21+ do not need the medical card for adult-use retail, but medical-program privileges require registry enrollment.
At the dispensary: Bring the current patient card or digital credential and a valid government-issued photo ID.
Open the official patient instructions ↗Do not buy a generic “medical card” online
Only the credential, certification, recommendation, or registry process recognized by this state can authorize medical purchasing. Private evaluation services do not replace state approval where approval is required.
Travel, work, housing, and federal edges
- STATE LINESDo not take cannabis across a state border—even between two adult-use states.
- FEDERAL PROPERTYState permission does not control federal buildings, lands, installations, or federal transportation rules.
- WORKLegal possession does not guarantee workplace use or protection from a lawful drug policy.
- HOUSINGSmoking, cultivation, and possession can be restricted by leases, federal housing rules, or property policy.
- TRIBAL LANDTribal law and jurisdiction can differ from the surrounding state; verify with the relevant tribal authority.
Six-month legal direction
A 24% wholesale tax took effect ↗
Michigan's new wholesale cannabis tax took effect January 1 and remains subject to litigation and a repeal bill. It affects market economics, not the adult possession baseline.
