Weed Laws and Regulations for Michigan
Michigan is one of the most cannabis-friendly states in the U.S., but marijuana laws can still be confusing. Since legalization, the state has built a detailed regulatory framework balancing access and safety. Whether you’re a medical patient, recreational consumer, or visitor, this guide explains Michigan’s cannabis laws—covering possession limits, taxes, consumption rules, and cultivation rights.
Is Weed Legal in Michigan?
Yes. Both medical and recreational marijuana are legal. Medical cannabis was legalized in 2008 under the Michigan Compassionate Care Initiative, allowing patients to possess up to 2.5 ounces and grow 12 plants. Recreational use followed in 2018 through the Michigan Regulation and Taxation of Marihuana Act (MRTMA).
Purchase & Possession Limits
Possession limits differ for recreational and medical users:
- Recreational: Adults 21+ may possess up to 2.5 ounces in public and 10 ounces at home. Up to 12 plants may be grown for personal use.
- Medical: Patients may possess up to 2.5 ounces, cultivate 12 plants in a locked area, and purchase up to 10 ounces per month. No excise tax applies to medical sales.
Michigan law sets possession and monthly purchase limits, not explicit daily purchase caps.
Places Where Use Is Prohibited
- Public areas such as parks, sidewalks, and streets
- Vehicles (driving or parked), unless explicitly permitted in private settings
- Rental properties where landlords prohibit smoking or vaping
- Federal land (airports, military bases, etc.)
Cannabis use is only allowed on private property or licensed consumption establishments.
Taxes on Cannabis
Recreational marijuana is subject to:
- 10% excise tax at retail sale
- 6% Michigan sales tax (applied on top of purchase + excise)
Medical cannabis is only subject to the 6% sales tax—no excise tax applies.
Example Tax Calculations
For a $100 purchase:
- Recreational: $10 excise + $6.60 sales tax = $116.60 total
- Medical: $6 sales tax = $106 total
Consumption Locations
Cannabis may be consumed on private property. Licensed “designated consumption establishments” may also operate under LARA rules. As of January 1, 2025, these venues may serve food, drinks, and host events under AB 1775.
Cultivation Rules
Adults 21+ may grow up to 12 plants for personal use. Plants must be in a locked, enclosed space and hidden from public view. Medical caregivers may grow up to 12 plants per registered patient (max 60 for five patients) under the same security requirements.
Only 10 ounces may be stored at home without additional restrictions. Exceeding limits or growing in public view can result in fines or charges.
Medical Marijuana Program
Established in 2008, Michigan’s medical program allows registered patients and caregivers to possess up to 2.5 ounces and grow 12 plants. Dispensaries were formally regulated in 2016, introducing a 3% tax and permitting edibles, tinctures, and topicals.

Regulation & Oversight
The Cannabis Regulatory Agency (CRA), under Michigan’s Department of Licensing and Regulatory Affairs, oversees growers, processors, retailers, and testing labs. The CRA uses the METRC seed-to-sale system to track all cannabis activity statewide.
Local municipalities may regulate or ban cannabis businesses. The CRA enforces compliance through inspections, license suspension, or fines.
Product Safety & Testing
All cannabis sold in Michigan must pass lab testing for THC/CBD potency, pesticides, heavy metals, and contaminants. Packaging must include cannabinoid content, serving size, and warnings. Products that fail safety testing must be remediated or destroyed.
These standards ensure safe, consistent products for medical and recreational users alike.
Out-of-State Visitors
Visitors 21+ can purchase and possess cannabis under recreational rules. Michigan does not recognize out-of-state medical cards. Transporting cannabis across state lines remains illegal under federal law.
Grow Your Own Cannabis
Michigan residents 21+ may grow up to 12 plants at home. Plants must be enclosed, locked, and hidden from public view. Medical caregivers may grow more if serving multiple patients, subject to CRA rules.
While home harvests may exceed 2.5 ounces, only 10 ounces can be stored without special storage. Always check your local municipal regulations before growing.
