Medical marijuana seen at risk following move by Sessions

When U.S. Attorney General Jeff Sessions green-lighted federal prosecutions of marijuana lawbreakers, the vast majority of U.S. states that allow some form of medical marijuana were unexpectedly placed at risk of a crackdown and are warily watching developments. Forty-six states - including Sessions' home state of Alabama - have legalized some form of medical marijuana in recent years, according to the National Conference of State Legislatures.
