OSHKOSH, WI — A forum in Oshkosh Wednesday night discussed legalizing marijuana in Wisconsin.  The forum hosted by the Fox Valley ACLU, featured medical experts and law enforcement.   In the November election, Colorado and Washington became the first two states to legalize recreational marijuana.  Wednesday, the panel discussed why Wisconsin should be next.  But opponents say pot is a gateway drug that could fall into the wrong hands, like teens and youth, and could lead to harder drugs.
