Michigan marijuana laws

Michigan Marijuana Laws 2026

Marijuana is fully legal in Michigan in 2026 for both recreational and medical use. Michigan voters approved recreational cannabis in November 2018 (Proposal 1) and adult-use sales launched in December 2019. A significant 2026 development: a new 24% wholesale cannabis excise tax took effect January 1, 2026, raising prices at the register. Adults 21 and older can possess up to 2.5 oz in public, grow up to 12 plants at home, and purchase from hundreds of licensed dispensaries statewide.

Last reviewed: May 2026 — laws change, always verify with a licensed attorney.

Recreational use

Vehicle searches — cannabis smell As of April 2025 (MI Supreme Court), smell of marijuana alone is no longer enough for police to search a vehicle without a warrant

Note on municipal access: Michigan allows municipalities to opt in or opt out of retail cannabis. Roughly 30% of cities and townships permit adult-use retail. If you are traveling in Michigan, check local availability — not every community has a licensed dispensary.

Michigan medical marijuana program

Michigan voters approved medical cannabis in 2008 (Proposal 1). The program is still active, though registered patient numbers have fallen sharply since recreational legalization — down roughly 75% from peak enrollment. A medical card still provides advantages: excise taxes do not apply to medical cannabis purchases, and patients have higher purchase limits.

Program established 2008 (Proposal 1)
Registry fee $40
Patient possession limit 2.5 oz usable marijuana
Patient purchase limit 2.5 oz per day, not to exceed 10 oz per month
Home cultivation Yes — up to 12 plants in an enclosed, locked facility
Excise tax on purchases Exempt (significant savings vs. recreational buyers)
Caregivers Yes — must be 21+, no drug felony, no violent felony ever; up to 5 patients
Out-of-state cards accepted Yes — if the other state also offers reciprocity to Michigan patients

Qualifying conditions

A licensed physician must certify that the patient has at least one of the following: Alzheimer’s disease, ALS, arthritis, autism, cachexia/wasting syndrome, cancer, cerebral palsy, colitis, chronic pain, Crohn’s disease, glaucoma, HIV/AIDS, inflammatory bowel disease, Hepatitis C, nail patella, nausea, OCD, Parkinson’s disease, PTSD, rheumatoid arthritis, seizures, severe and persistent muscle spasms, spinal cord injury, Tourette’s syndrome, or ulcerative colitis.

Taxes, expungement, and consumer rights

What taxes apply to Michigan cannabis purchases?

As of January 1, 2026, Michigan applies a 24% wholesale cannabis excise tax (signed in October 2025) plus a 6% retail sales tax on adult-use purchases. This tax increase was controversial — passed 19-17 in the Senate — and has already prompted some layoffs and store closures in the industry. Medical cannabis purchases remain exempt from the excise tax, which is a significant financial advantage for registered patients.

Can your record be expunged?

Yes. Michigan’s Clean Slate Legislation (signed October 2020, effective April 11, 2021) allows people with prior marijuana convictions for conduct that is now legal to petition for expungement. Unlike most expungements, there is no required waiting period. Automatic expungement launched in 2023 for qualifying offenses. If you have a prior marijuana conviction you believe may qualify, consult a Michigan attorney — there is no waiting period.

Vehicle searches — what changed in 2025

As of an April 2025 Michigan Supreme Court ruling, the smell of marijuana alone is no longer sufficient reason for police to search your vehicle without a warrant. This is a meaningful change for adult cannabis users. However, if there are other factors supporting probable cause, a search may still be legally conducted. If you believe your rights were violated in a vehicle stop, consult a Michigan defense attorney.
