Key takeaways

Minnesota Statutes 342.09 sets adult-use amounts including 2 oz flower in public, 2 lb flower at home, 8 g concentrate, and 800 mg edible THC.

OCM says one residence may grow up to eight plants, no more than four mature, under stated primary-residence and locked-space conditions.

Federal property, certain schools/facilities, vehicles, and smoking/vaping restrictions create location boundaries; check OCM’s current list.

Minnesota possession amounts by location

Minnesota OCM's current adult-use page says a person 21 or older may possess or transport up to 2 ounces of flower in public, possess up to 2 pounds of flower at a private residence, and possess or transport up to 8 grams of concentrate or edible products containing a combined 800 milligrams or less of THC. The linked Minn. Stat. §342.09 is the statutory reference; its official indexed text was checked, but the PDF did not load in this pass. Product and location categories matter. See OCM Adult-Use Cannabis and §342.09.

Home cultivation and location rules

OCM says up to eight plants may be grown at one residence, with no more than four mature, when it is the primary residence of someone 21 or older. Plants must be enclosed, locked, and not open to public view. OCM also lists prohibited locations and exceptions, so do not treat state permission as permission everywhere.

Medical and federal boundaries

Registered medical products follow distinct rules. OCM lists federal property, operating vehicles, and several other settings as restricted; local ordinances may also prohibit public smoking or vaping. See U.S. cannabis-law basics for the separate federal boundary.
