Since I cannot edit. Anslinger not only is responsible for enacting marijuana prohibition nationally, but also for his influence on UN/world. Our friends in Saudi Arabia behead marijuana smugglers/dealers, and equate it with murder, rape, witchcraft.
Anslinger made it a race war on Mexicans, emigrating for jobs and a bit of freedom. Thus, he actually, unknowingly, did his part in writing the Handbook for the Southern Strategy, which Nixon, among others, so well defined:
"You want to know what this was really all about? The Nixon campaign in 1968, and the Nixon White House after that, had two enemies: the antiwar left and black people. You understand what I'm saying? We knew we couldn't make it illegal to be either against the war or black, but by getting the public to associate the hippies with marijuana and blacks with heroin, and then criminalizing both heavily, we could disrupt those communities. We could arrest their leaders, raid their homes, break up their meetings, and vilify them night after night on the evening news. Did we know we were lying about the drugs? Of course we did."--John Ehrlichman, Nixon's top aide.
