The money quote:
> "You want to know what this was really all about?” he asked with the bluntness of a man who, after public disgrace and a stretch in federal prison, had little left to protect. “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 blacks, 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.”
The origins of that quote are dubious. Author Dan Baum claims that Nixon lawyer John Ehrlichman made this confession to him back in 1994, but Dan waited until 2016 to publish it-- long enough that most people in Nixon's inner circle (including Ehrlichman himself) have died and couldn't set the record straight.
However, Pat Buchanan (long time adviser to Nixon) said in an interview that the quote is nonsense.
Not a fan on the War on Drugs, especially not after reading that. On the other hand, I'm strongly in favor of enforcing the laws on the books, and if there is a bad law it should be changed, not ignored.
