Yes, weed is legal in Minnesota for adults 21 and older. The state legalized adult-use cannabis in 2023 under Chapter 342 of the Minnesota Statutes, and the first non-tribal recreational dispensaries opened to the public in September 2025. Minnesota also runs a separate medical cannabis program for qualifying patients. But legal at the state level is not the same as legal everywhere: cannabis is still a Schedule I controlled substance under federal law, and that creates consequences for firearms, federal housing, and interstate travel that catch a lot of Minnesotans off guard.
How Much You Can Legally Have
The possession limits depend on where you are. If you’re out in public, you can carry up to two ounces of cannabis flower, up to eight grams of concentrates, and edible products containing up to 800 milligrams of THC in total. At home, the flower limit rises to two pounds. The 800-milligram edible cap includes lower-potency hemp edibles you may have bought at a liquor store or taproom.
You can also gift cannabis to another adult who is at least 21, as long as no money changes hands and the amount stays within the public possession limits.1Minnesota Office of the Revisor of Statutes. Minnesota Statutes Section 342.09 – Personal Adult Use of Cannabis Businesses cannot use “free gifts” as a workaround for unlicensed sales, and giving any amount to someone under 21 is a separate violation with civil and criminal penalties attached.
Where to Buy It
Licensed cannabis retailers are the only legal source of adult-use cannabis in Minnesota. The first non-tribal recreational dispensaries opened in September 2025, roughly two years after the Legislature passed the legalization law. RISE and Green Goods, which had previously operated as medical-only dispensaries, were among the first to begin recreational sales. The Office of Cannabis Management is still issuing licenses, so more stores continue to open.
Lower-potency hemp edibles are a separate category. Capped at 5 milligrams of THC per serving and 50 milligrams per package, these products are regulated under Minnesota’s hemp law rather than by the Office of Cannabis Management, and they’re sold in bars, restaurants, and liquor stores across the state. The THC gummies at your local brewery taproom are hemp edibles, not the same products carried by a licensed dispensary.
Growing Your Own
Adults 21 and older can grow cannabis at home. A single residence is capped at eight plants total, with no more than four mature, flowering plants at any one time.1Minnesota Office of the Revisor of Statutes. Minnesota Statutes Section 342.09 – Personal Adult Use of Cannabis
The plants have to be at your primary residence, in an enclosed, locked space that isn’t visible to the public. A locked greenhouse in the backyard meets the rule. An open garden bed does not. The same limits apply indoors or out.
Where You Can and Cannot Use It
Cannabis use is allowed on private property, including your own home or someone else’s property with the owner’s permission, and at businesses or events specifically licensed for on-site consumption. Smoking or vaporizing cannabis is prohibited almost everywhere else, including:
- Any indoor or outdoor area open to the general public
- Buses, trains, and light rail
- School buses and the grounds of any child care program
- Any place of employment
- Correctional facilities and state treatment programs
Local governments can adopt ordinances making public use a petty misdemeanor, which is the lowest-level offense under Minnesota law and carries no jail time.2Minnesota Office of the Revisor of Statutes. Minnesota Statutes Section 152.0263 – Cannabis Possession Crimes A useful rule of thumb: if you can’t smoke a cigarette somewhere, you can’t smoke cannabis there either.3Office of Cannabis Management. Guidance on Where to Use Medical Cannabis
Driving
Driving under the influence of cannabis is a crime under the same DWI statute that covers alcohol. Minnesota does not set a specific THC blood-level cutoff the way it does with 0.08 for alcohol. Any impairment from cannabis while operating a motor vehicle qualifies, and penalties follow the same four-degree DWI framework, from a first-offense misdemeanor up to a felony for repeat offenders.4Minnesota Office of the Revisor of Statutes. Minnesota Statutes Section 169A.20 – Driving While Impaired Crime
Medical Cannabis
Minnesota’s medical cannabis program runs through the Division of Medical Cannabis within the Office of Cannabis Management. To enroll in the patient registry, you need a diagnosis from a licensed healthcare practitioner for a qualifying condition. The named list includes cancer, glaucoma, HIV/AIDS, ALS, seizures and epilepsy, multiple sclerosis, inflammatory bowel disease, PTSD, chronic pain, autism spectrum disorder, obstructive sleep apnea, and terminal illness, among others. Minnesota also has a catch-all: any condition for which a healthcare practitioner recommends cannabis as a treatment.5MN.gov. Qualifying Medical Conditions – Division of Medical Cannabis
Medical cannabis retailers cannot dispense more than a 90-day supply to a patient, registered caregiver, spouse, parent, or guardian.6Minnesota Office of the Revisor of Statutes. Minnesota Statutes Section 342.51 – Medical Cannabis Retailers
What’s Still Illegal Under State Law
Selling cannabis without a state-issued license is not legal at any amount. Civil penalties from the Office of Cannabis Management scale with the quantity sold and can reach $1,000,000 or three times the retail value for the largest tiers, and criminal prosecution can be added on top.1Minnesota Office of the Revisor of Statutes. Minnesota Statutes Section 342.09 – Personal Adult Use of Cannabis
Giving cannabis to anyone under 21 is prohibited even as a free gift, and the statute treats it as a separate violation from adult-to-adult gifting. Using cannabis at work, or showing up impaired, remains grounds for discipline the same as alcohol.
Employment Protections
Minnesota’s law protects most workers from being disciplined for off-duty cannabis use, and it bars most employers from requiring pre-employment or random cannabis drug testing. Testing is still allowed when an employer has reasonable suspicion of on-the-job impairment, or after a workplace accident where drug use may have been a factor. If you test positive under a lawful reasonable-suspicion test, the employer must offer an evaluation and treatment option before firing you, though refusing that offer can itself be grounds for termination.
Safety-sensitive positions are carved out, including jobs regulated by the federal Department of Transportation. Commercial truck drivers and other DOT-covered workers remain subject to federal drug testing rules that still treat cannabis as disqualifying.7U.S. Department of Transportation.

Federal Law Still Applies
This is where legal Minnesota residents most often get into trouble. Cannabis is still a Schedule I controlled substance under federal law. A December 2025 Executive Order directed the Department of Justice to complete a rulemaking process that would reschedule cannabis to Schedule III, but as of early 2026 that process is pending and cannabis is still Schedule I.8The White House.

Firearms
Federal law prohibits anyone who is “an unlawful user of or addicted to any controlled substance” from possessing firearms or ammunition. Because cannabis remains Schedule I, any cannabis user is technically a prohibited person under 18 U.S.C. ยง 922(g)(3), regardless of Minnesota law.9Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts ATF Form 4473, filled out when buying a firearm from a licensed dealer, asks directly whether you’re an unlawful user of a controlled substance. Answering falsely is a federal felony.10Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). Identify Prohibited Persons
Federal Property
Cannabis possession on federal land is prosecuted under federal law regardless of state legalization. That covers national parks, military installations, federal courthouses, and post offices. A first offense is a misdemeanor with up to a year in jail and a minimum $1,000 fine. A second offense carries a mandatory minimum of 15 days and fines up to $2,500. Third and later offenses carry a 90-day mandatory minimum and up to three years in prison. In Minnesota, the Boundary Waters Canoe Area Wilderness and Voyageurs National Park are both federal land where these rules apply.
Federally Assisted Housing
If you live in Section 8 or other federally subsidized housing, federal law requires your landlord to include lease provisions allowing eviction for cannabis use. The Quality Housing and Work Responsibility Act bars property owners from permitting cannabis use on the premises and requires them to deny admission to applicants who are current users. Owners have some discretion on whether to evict existing tenants, but they cannot affirmatively allow use.11U.S. Department of Housing and Urban Development. Use of Marijuana in Multifamily Assisted Properties
Interstate Travel
Carrying cannabis across state lines is a federal offense even when both states have legalized it. TSA officers don’t actively search for cannabis, but if they find it during screening, they refer the matter to local law enforcement. In Minnesota, local officers may take no action for amounts within the state’s legal limits. Flying to a state where cannabis is illegal is a different story, and could mean arrest at your destination. Leaving cannabis at home before any interstate trip is the safe move.
Taxes
Minnesota applies a 10 percent state excise tax on adult-use cannabis purchases, on top of standard state sales tax. This was built into the 2023 legalization law. At a licensed dispensary the excise tax is already included in or added to the listed price. Medical cannabis is taxed differently and generally carries a lower overall tax burden than recreational product.
