^This. It's always funny to me when someone uses hemp as their argument for the legalization of weed. Also, don't you think there are big industries currently making money from the products we use? When resources get scarse, like oil, the prices rise. Of course they can make oil from hemp, just as they can do it with vegetables and compost, but cars arent manufactured that way because the oil industry is such a rich economic entity. Maybe in the future.
Anyways, go smoke a hemp t-shirt!
