Senators in Minnesota passed a bill Saturday, May 20, 2023, that would legalize recreational marijuana for people over the age of 21, making it the 23rd state to legalize adult-use cannabis. Tim Walz signed a bill Tuesday to legalize recreational marijuana for people over the age of 21 starting in August, making Minnesota the 23rd state to legalize the substance for adults. Among them was one of the first governors in the U.S. to openly support marijuana legalization. In 2021, the Democratic-controlled House passed a legalization bill with several Republicans voting yes, but the GOP-controlled Senate never gave it a vote. Last year, the Legislature passed a bill legalizing THC in edible or drinkable form if it’s derived from hemp.
