The Nebraska legislature has also stopped an effort to grow it legally. Makes no sense. You can't smoke it (well I guess you can smoke anything, but you'll get just as high smoking lettuce as this stuff), and if someone was raising the good stuff nearby, the hemp would cross pollinate and actually ruin the illegal crop. It would make another crop available to farmers and requires much less water than corn.
A little story - my cousin and I were coming home from college or going back, can't rememeber. We pulled off the highway onto a gravel road to take a leak and saw a state trooper car drive by. We were congratulating ourselves on how lucky we were to miss meeting him when we suddenly realized that we were standing in a ditch weed patch that reached way over our heads. We wasted no time in getting out of there!
