FILE - In this May 23, 1966, file photo, people roll joints at a marijuana party near the University of California at Berkeley campus in Berkeley, Calif. In 2012, Washington state and Colorado voted to legalize and regulate its recreational use. But before that, the plant, renowned since ancient times for its strong fibers, medical use and mind-altering properties, was a staple crop of the colonies, an "assassin of youth," a counterculture emblem and a widely accepted - if often abused - medicine. On the occasion of “Legalization Day,” Thursday, Dec. 6, 2012, when Washington’s new law takes effect, AP takes a look back at the cultural and legal status of the “evil weed” in American history.
