Michigan has one of the country's biggest cannabis markets and generous personal limits. Here's what you can carry and grow, and what the new wholesale tax means.

TL;DR

Adults 21+ can carry up to 2.5 ounces (no more than 15 grams of concentrate) and keep up to 10 ounces at home. Home grow is 12 plants per household. Public use is a civil infraction. Retail sales carry a 10% excise tax plus 6% sales tax, and a new 24% wholesale tax took effect January 1, 2026.

Michigan voters approved medical cannabis in 2008 and recreational cannabis with Proposal 1 in 2018. Adult-use stores opened in December 2019, and Michigan now has one of the largest markets in the country, with more than $3 billion in sales in 2025. The Cannabis Regulatory Agency (CRA) regulates the market.

Is weed legal in Michigan?

Yes, for adults 21 and older. Bring a valid ID showing you're 21+. Visitors can buy too. Many towns have opted out of allowing stores.

How much can you carry and keep?

Limit Adults 21+
On you Up to 2.5 ounces, with no more than 15 grams of concentrate
At home Up to 10 ounces, with anything over 2.5 ounces locked up

Carrying more than 2.5 ounces, up to 5 ounces, is a civil infraction with a fine.

Where can you use it?

Private property, with the owner's permission. Using cannabis in public is a civil infraction with a fine of up to $100. Some cities license consumption lounges and events. Landlords can ban smoking and growing.

Can you grow cannabis at home?

Yes. Adults 21+ can grow up to 12 plants per household, in an enclosed, locked area that isn't visible to the public. Growing 13 to 24 plants is a misdemeanor.

Medical cannabis in Michigan

Michigan's medical program still exists, but adult-use stores now sell most cannabis. Medical purchases skip the 10% excise tax.

Taxes on cannabis in Michigan

  • 10% excise tax and 6% sales tax at the register
  • A new 24% wholesale marijuana tax, effective January 1, 2026, charged when growers sell to retailers. It's built into shelf prices, and industry groups are challenging it in court.

Driving and work

Driving impaired is illegal. Michigan employers can still refuse to hire, or fire, people for cannabis use, though the state itself stopped testing most job applicants for cannabis.

Old marijuana convictions

Michigan lets people set aside past misdemeanor cannabis convictions that wouldn't be crimes today, and the state's Clean Slate law automatically clears many older misdemeanors.

Is anything changing in 2026?

Yes, the 24% wholesale tax. State officials expect it to shrink the wholesale market, and some stores have warned of higher prices and closures. The legal challenges were still pending at our last review. Possession and home-grow limits haven't changed.

Federal law in 2026

Federal law still treats recreational cannabis as illegal. In April 2026, the federal government moved marijuana sold under a state medical license (and FDA-approved cannabis medicines) to Schedule III, but adult-use cannabis is still Schedule I. That means it's still banned on federal land and can't legally cross state lines, even between two legal states.

Separately, a federal ban on intoxicating hemp products takes effect in two steps: synthetic and converted cannabinoids like delta-8 lose their legal status on November 12, 2026, and naturally derived hemp THC (THCA flower, hemp delta-9 edibles and drinks) on December 11, 2026.
