On a trip through Western Illionois me and a few friends saw some "ditch weed" growing right off the highway in the edge of a cornfield, it got none of us high, it gave us all headaches and was just what was grown for hemp during WW2 by farmers, little to no THC at all, it was hemp making cannabis, we took a few 4 foot plants with scraggly buds, no seeds, and it was the worst tasting shit I hav ever had, and produced no high, only a bad headache! lol, In the midwest wild hemp plants of cannabis still grow in and around cornfields, and the shit is so bad ,cops do not even bother it!!! lol..Some interprising growers have planted a few plants of good weed intermixed around a bunch of "ditchweed hemp plants" and top them off to keep them from being to tall and shit, and it's any easy way to conceal a small grow of good cannabis, among hemp plant cannabis, you just have to make sure no one can get close enough to actually see nice buds with crystals and all on the plants and make sure none of your plants get pollintaed by the shit weed!!
