I didn't know about the link with Logging. I remember seeing something a while ago about how it was banned during some war or something as a political weapon. Basically as it was used for sails, rope etc in the war ships of the time the banning of production had a direct effect on the military. I think this backfired and the USA ended up importing hemp at great cost from abroad. I can't remember exactly where I saw/read it but this is quite a nice brief history if you haven't alreaday seen it:
