Yes legalize. It shouldn't have been banned to begin with. It makes more sense to ban alcohol than cannabis if we're just talking from a public safety perspective. It was actually banned because the lumber industry wanted to chop down trees for paper rather than letting hemp take the lead.
That's a new take for me, I've heard it was an aspect of Reagan's war on drugs, it was an obstacle in the Vietnam war, it was amn attack against the black and Jamaican community, was big pharma wanting to clear the way for over the counter pain killers, and that the tobacco companies weren't allowed to grow it so they made sure no one else would.
