It is now legal for Minnesotans 21 and older to buy certain edibles and beverages containing small amounts of THC. A new law allows for the sale and purchase of edibles and beverages that contain up to 5 milligrams of tetrahydrocannabinol (THC) per serving and 50 milligrams per package, and no more than .03% THC by weight. Although the Minnesota Board of Pharmacy has authority over drug products intended for human or animal consumption, the board will not test or approve such products.
