In this Oct. 5, 2013 photo, Derek Cross, a chef who specializes in cooking with hemp, demonstrates the burning properties of hemp oil, which he touts as a digestible bio fuel, during the first known harvest of industrial hemp in the U.S. since the 1950s, at a farm in Springfield, Colo. America is one of hempís fastest-growing markets, with imports largely coming from China and Canada. Most of that is hemp seed and hemp oil, which finds its way into granola bars, soaps, lotions and even cooking oil. (AP Photo/Kristen Wyatt) ( Food And Farm Industrial Hemp )
