Decriminalize the use of cannabis and automatically expunge all prior cannabis use convictions. Biden believes no one should be in jail because of cannabis use. As president, he will decriminalize cannabis use and automatically expunge prior convictions. And, he will support the legalization of cannabis for medical purposes, leave decisions regarding legalization for recreational use up to the states, and reschedule cannabis as a schedule II drug so researchers can study its positive and negative impacts. --
