FILE- This April 22, 2009, file photo, shows former President Thomas Jefferson's home, Monticello, in Charlottesville, Va. Jefferson and George Washington both grew hemp and puzzled over the best ways to process it for clothing and rope. Indeed, cannabis has been grown in America since soon after the British arrived. Jefferson went on to invent a device for processing hemp in 1815. 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.
