At a campaign stop in Urbandale, Iowa, Tuesday, Republican presidential candidate Herman Cain said he supports letting states establish their own laws regarding medical marijuana.

“If states want to legalize medical marijuana, I think that’s a state’s right,” Cain said, according to NBC News. “Because one of my overriding approaches to looking at all of these issue –most of them belong at the state, because when you do something federally . . .  you try to force one-size-fits-all.”
