I remember hearing stories of Chicagoans coming down here to north-west Indiana (100 miles from Chicago) and driving through fields to get the “marijuana” growing along the ditch banks. It was wild hemp plants that remained from when hemp was grown in the fields to replace the hemp from the Philippines that the US Navy used to make ropes for its ships from. That was back in the 50’s - 70’s.
My family grew acres of it for the war effort. It’s hard to get rid of as a volunteer crop. I’ve mowed and sprayed a lot of it. I used to joke about running the bailed thro it, putting the bale in an enemy’s car trunk, and calling the cops. As far as smoking, it’s useless. I did make a great way to camouflage real pot plants for some in my area.
