> There is considerable information back from the 80s to suggest that the US war on drugs was actually a system to enable racial discrimination.
It also was a way to increase the private jails business, which in fact peaked during the 80s, but the racial and political discrimination stands too. The following piece from the Wikipedia article about the War on Drugs is telling.
"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 (White House Counsel and Domestic Affair advisor during the Nixon administration)
