Hemp - the next King Cotton in the US?

I found this chart on another blog - http://jobsanger.blogspot.com - and it struck me that there may be another reason that hemp is illegal to grow in the US...COTTON! Cotton growers might have some real competition if restrictions on growing hemp were lifted. (from Wikipedia) "In modern times hemp is used for industrial purposes including paper, textiles, clothing, biodegradable plastics, construction (as with Hemcrete and insulation), body products, health food and bio-fuel. Hemp is thus legally grown in many countries across the world including Spain, China, Japan, Korea, France, North Africa and Ireland. Although hemp is commonly associated with marijuana (hemp's THC-rich cousin), since 2007 the commercial success of hemp food products has grown considerably." Woody Harrelson has been advocating this for years and serves as a member on NORML's advisory board. Now we need to get a hemp lobby the size of the COTTON lobby.
