Is there anything you can’t do with industrial hemp? Turn its fiber into paper or cloth? Yep. Eat its oil or seeds? You can do that, too. Smoke it? Well, you can, but you won’t get the desired effect: industrial hemp has only trace amounts of THC (the active ingredient in hemp’s cousin, marijuana). One thing you definitely can’t do: grow it in the United States. Despite the multiple potential uses (almost all of which create a much smaller environmental footprint than conventional materials), it’s still illegal to farm industrial hemp here.
