Legally Speaking

This is general information, not legal advice. Rules and local ordinances change, so check the Minnesota Office of Cannabis Management (mn.gov/ocm) for current details. Current as of October 1, 2026.

Possession & Use Limits

• Public limit: Adults 21+ may carry up to 2 oz of flower, 8 g of concentrate, or edibles containing up to 800 mg THC.

• Home limit: You may keep up to 2 lb of flower at your private residence.

• Gifting: Adults 21+ may gift another adult 21+ up to the public possession limits, with no money or payment involved.
   

Home Cultivation

• You may grow up to 8 cannabis plants per residence, with no more than 4 mature (flowering) plants at a time.

• Plants must be in a locked, enclosed space that isn't visible to the public.

• Home-grown cannabis can't be sold.

• Landlords and HOAs may restrict growing.
   

Where You Can (and Can't) Use

• Consumption is generally allowed on private property that isn't open to the public, unless the property owner prohibits it. Landlords can bar use through a lease.

• Smoking or vaping cannabis is not allowed in a vehicle, on school grounds, in correctional facilities, anywhere a minor could inhale it, on federal land, in federally subsidized housing, or in multi-unit housing, including balconies and patios.

• Minnesota's Clean Indoor Air Act now covers cannabis and vaping devices, so use is prohibited in virtually all indoor workplaces.

• Local governments may restrict public smoking and vaping, similar to tobacco rules.
   

Driving & Impairment

• Driving while impaired by cannabis is illegal, and using cannabis in a motor vehicle is not allowed.

• Cannabis in a vehicle must be in its original, sealed packaging, or stored where the driver and passengers can't reach it, such as the trunk. An open or improperly packaged product is a misdemeanor (up to 90 days in jail and a $1,000 fine), even if you aren't impaired.

• Police can't search your vehicle based solely on the smell of cannabis. Visible cannabis products can still give an officer a lawful reason to search.

• Law enforcement has been developing roadside impairment testing, including saliva tests.

• Being a medical cannabis patient doesn't protect you from an impaired-driving charge.
   

Employment & Housing

• Employment: Employers can't require job applicants to take a cannabis test, unless state or federal law requires it. Employers may test current employees in limited situations, including reasonable suspicion, after a workplace accident, in treatment programs, and for safety-sensitive positions. Employers can also prohibit use or impairment at work, and positions covered by federal law or contracts may have stricter rules.

• Housing: Landlords can prohibit smoking and vaping, and can also restrict use or growing through the lease. Federally subsidized housing is excluded from state protections.
   

Gun Ownership

Federal law still bars "unlawful users" of controlled substances, including cannabis, from possessing firearms, and state legalization doesn't change that. In June 2026, however, the U.S. Supreme Court ruled in United States v. Hemani that the ban can't be applied to a cannabis user based on use alone, without a showing of dangerousness. The ruling is narrow, and the law and ATF forms are still in flux. If you use cannabis and own or want to buy a firearm, talk to a lawyer who handles firearms law.
