I understand it make a good strong rope and was a good canvas for sails...which is probably why Columbus and the Pilgrims were growing it, and George Washington, too grew 'the Indian hemp,' more for such purposes...not to take away from the valid point that it's an ancient, worldwide useful plant and it's demonization to put people in prison or start wars is wrong.

Look for a Video called The Marijuana Conspiracy.

It goes into large amounts of detail on this subject and gives the real reasons behind its legal state, it has nothing whatsoever to do with the smokeable variety and everything thing to do with the threat posed to Dupont Petrochemicals by industrial hemp.
Dupont has friends on certain government committees and strong armed it past congress and the medical association who were lied to.
