Democratic Gov. Tim Walz of Minnesota signed a bill into law on Tuesday legalizing recreational marijuana use in the state. With Walz’s signature, Minnesota becomes the 23rd state to legalize adult-use cannabis and the third Midwestern state to do so. Under the measure, Minnesota residents who are 21 years and older will be able to possess up to two ounces of marijuana flower in public and two pounds at home starting August 1. It also gives people with marijuana convictions a chance to clear their records by automatically expunging low-level convictions and establishing a review board to determine eligibility for higher-level offenses.  Read the article here.
