In colonial times, it was illegal to NOT grow hemp. It was a need for everything from paper to clothing back then. Also, if they legalized hemp, it would cut back drastically on the amount of trees we kill just to get paper, not to mention for construction purposes. Trees are actually only 35% cellulose, the part we used for paper and wood, hemp on the other hand is 80% cellulose. Those are clear numbers. The real reason that it won't be legalized is because of the gas industry. It can be used to make ethanol, grows faster than corn, and would be actually cleaner burning than even corn ethanol. The reason is because America is still too capitalistically minded, and can't get their heads out of there ass's to realize this will help the economy.
