Possession and use
An adult 21 or older may carry up to two ounces of flower in public, keep up to two pounds of flower at a private residence, carry eight grams of concentrate, and possess edibles totaling no more than 800 milligrams THC. These form-specific limits come from section 342.09 and the OCM guidance.
The public flower amount and private-residence flower amount differ by a factor of sixteen: two ounces versus two pounds. The law also gives separate concentrate and edible THC limits. A person moving product in public should use the public amounts, even if the same product could be held at home.
Medical access
Minnesota's medical cannabis patient registry continues alongside adult use. The current statute also recognizes visiting patients from other U.S. jurisdictions and permits a licensed cannabis business with a medical cannabis retail endorsement to distribute medical cannabis flower or medical cannabinoid products to them. A visitor must show a valid home-program medical registration card or equivalent and qualifying photo ID. The seller must apply a patient-specific label. The visiting purchase does not enroll the visitor in Minnesota's resident registry or authorize cross-border transport.
Home cultivation
At one primary residence an adult may grow eight plants total, of which no more than four may be mature and flowering. The grow must be enclosed, locked and out of public view. This is a residence limit, not eight plants for every adult in a household.
OCM specifies a single-residence limit of eight plants, of which no more than four may be mature and flowering. The grow must be at the primary residence of an adult 21 or older. Enclosed and locked are cumulative requirements; simply hiding plants behind a fence does not satisfy the stated security rule.
Buying legally
Adults 21 or older may use licensed adult-use retail options subject to ID and transaction rules. Medical cannabis is distributed through licensed businesses with a medical retail endorsement. A visiting patient may use that medical channel with a valid out-of-state medical credential and qualifying photo ID under section 342.51, subdivision 2a. A lower-potency hemp edible retailer is not necessarily licensed to sell high-THC cannabis flower.
Taxes
OCM lists a 15% cannabis gross-receipts tax on taxable adult-use products, alongside the 6.875% state general sales tax and applicable local sales taxes. Medical cannabis sales are not taxed under the cited OCM guidance. Final checkout tax varies by place and product.
The state cannabis tax is based on retail gross receipts rather than being a tax on a consumer's possession. Ordinary state sales tax and the locality's applicable sales tax are additional for taxable adult-use products. OCM expressly excludes medical cannabis product sales from those taxes, so the channel of purchase matters.
Travel and transport
OCM says cannabis may not be used or possessed on federal property and prohibits impaired driving. Use is limited by property rules and smoke-free laws, including restrictions in multifamily housing. Neither the state possession limit nor a medical registration authorizes crossing a state line with cannabis.
