Where you can legally use cannabis in Michigan, and how much you can buy

In January 2025 Michigan's Cannabis Regulatory Agency counted 139 municipalities that had opted in to adult-use cannabis businesses and 1,370 that had opted out. That ratio frames the whole question of where you may use what you buy. Under the Michigan Regulation and Taxation of Marihuana Act (MCL 333.27954), an adult aged 21 or over may consume on private property with the consent of whoever owns or runs it, and in an area a municipality has designated for consumption and closed to anyone under 21. The Act does not cover a public place, use while driving, or smoking in the passenger area of a vehicle on a public road. You may carry 2.5 ounces, no more than 15 grams of it concentrate, and keep 10 ounces at home.

The law was written by petition, not by the Legislature: it is Initiated Law 1 of 2018, approved by voters that November. Its permissions are broad on quantity and narrow on place. Section 4 lists what the Act does not authorize, and that list, more than any lounge or shop, is the map a visitor needs: no use in a public place, none on school grounds or a school bus, none on the grounds of a correctional facility, and no smoking where the person who owns or manages the property forbids it.

The legal place to use cannabis outside a home is a designated consumption establishment: in the Cannabis Regulatory Agency's words, a commercial space it has licensed where adults 21 and over may consume cannabis on site. The license does not allow sales; a lounge may sell only if its owner also holds a retailer or microbusiness license. It runs for 1 year, and the applicant must show the agency, on its own attestation form, that the municipality has signed off. The agency's municipal guide, revised in March 2026, explains why that sign-off matters: a city, village or township keeps adult-use businesses out with an ordinance banning them outright, or lets them in with an ordinance that permits them, cap optional.

Detroit is one city that wrote lounges into its own law. Ordinance 2022-11 provides 15 designated consumption lounge licenses and 15 more reserved for equity applicants, and lets them open from 9 a.m. to 2 a.m. When the city announced its first adult-use retail licenses on 22 December 2022, it reported that no application for its 10 first-round lounge licenses had met every requirement. On 13 October 2026 we found no official list of open Michigan lounges that we could cite, so we name none. A venue that calls itself a lounge should be able to show you its state license.

The agency also licenses temporary marijuana events, and restated its requirements for them to licensees in February 2025. An event is a licensed occasion, not a standing place to go, and the license sits with the organizer.

A car is the clearest case. Section 4(1)(g) of the Act gives no protection to anyone who consumes cannabis while operating or in physical control of a motor vehicle, or who smokes it in the passenger area of a vehicle on a public way. Driving under the influence is outside the Act altogether. Carrying it is a separate question: MCL 750.474, a Penal Code section added in the 2011-2012 session for the medical program, makes it a misdemeanor, punishable by up to 93 days in jail or a $500 fine, to carry usable marihuana in a vehicle unless it is in a case in the trunk, or, with no trunk, in a case out of reach of the cabin. Courts have limited its reach over registered medical patients. We found no ruling that does the same for adult-use buyers, so the trunk is the cautious reading.

A hotel is private property, and the Act lets the person who owns or manages a property prohibit or regulate cannabis on it. A hotel that bans smoking in its rooms is within its rights, and so is one that bans cannabis outright. Ask at the desk, and read the room card; the hotel's rule binds you there.

A rented home is where the Act takes the tenant's side, a little. A landlord may ban smoking, but section 4 says a lease may not prohibit a tenant from lawfully possessing cannabis or consuming it by means other than smoking. A tenant under a no-smoking lease may keep an edible in the kitchen. They may not light a joint on the balcony.

Michigan law stops at the boundary of federal property. The National Park Service says possession or use of marijuana is prohibited in every unit it runs, whatever the state allows, and Michigan holds three of them that visitors plan trips around: Sleeping Bear Dunes and Pictured Rocks national lakeshores, and Isle Royale National Park. A legal purchase in Traverse City is an illegal possession on the dunes 25 miles west.

The Transportation Security Administration says marijuana remains illegal under federal law except for hemp products at or under 0.3% THC and FDA-approved drugs. Its officers do not search for drugs, but they refer what they find to law enforcement. Michigan's own regulator, in comments it filed on federal rescheduling on 22 July 2024, put the state-line rule plainly: cannabis cannot be taken across state lines, even between two states with legal programs. A visitor driving home to Ohio, Indiana or Wisconsin, or flying out of DTW, should plan to finish what they bought or leave it behind.

The possession rule has two numbers and a condition. An adult aged 21 or over may possess, use and transport 2.5 ounces, of which no more than 15 grams may be concentrate. At home the figure is 10 ounces, plus whatever comes from up to 12 plants grown there, and anything over 2.5 ounces must be kept in a container or area with locks. The dispensary side mirrors the personal limit: under the agency's rule R 420.506(3), a retailer may not sell more than 2.5 ounces, or more than 15 grams of concentrate, to one adult in one transaction.

At the register the arithmetic is the same in every Michigan town: a 10% excise, then the 6% sales tax charged on the price plus the excise, 16.6% in all. Since 1 January 2026 a 24% wholesale tax, paid by the grower or processor on the first sale to a retailer, has sat inside the shelf price; it never appears on the receipt. A registered medical patient pays the 6% sales tax and no excise.

46 Michigan stores are on our nightly list. On 13 October 2026, 44 of them returned a menu, and the deals below come from those menus. We read them every morning around 8 AM ET.
