Everyone should read the words of one of Nixon's top aides regarding why they started the war on drugs:

“The Nixon campaign in 1968, and the Nixon White House after that, had two enemies: the antiwar left and black people,” former Nixon domestic policy chief John Ehrlichman told Harper’s writer Dan Baum for the April cover story published Tuesday.

“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,” Ehrlichman said. “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.”

And yet the wikipedia entry for the war on drugs starts like this:

The war on drugs is a global anti-narcotics campaign led by the United States federal government, including drug prohibition, foreign assistance, military intervention, and counterterrorism, with the aim of reducing the illegal drug trade in the US.

Emphasis added. I would say that is flat out false. It may be the openly stated aim, but it is not the true aim, and they've admitted it. Just another reminder that these fascists know exactly what the fuck they're doing and that wikipedia is subject to propaganda influences.
