Could America's divide on marijuana be coming to an end?

The U.S. is divided when it comes to state and federal marijuana policy, but recent political developments could move the country toward a greater acceptance of cannabis.

Both major presidential candidates have signaled support for a federal policy change to reclassify marijuana as a less dangerous drug, and voters in several additional states will get a say this fall on legalization.

Though still illegal under federal law, public approval of marijuana has grown significantly — and so has the number of states where it's legally sold in stores.
