“You want to know what this was really all about?” Ehrlichman 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 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.

John D. Ehrlichman (l.), a top adviser to former President Richard Nixon (r.) is seen here in a 1972 photo. Ehrlichman, who died in 1999, admitted that the administration’s “War on Drugs” was actually a ploy to target left-wing protesters and African-Americans.
“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.”
In 1971, Nixon labeled drug abuse “Public Enemy No. 1” and signed the Comprehensive Drug Abuse Prevention and Control Act, putting into place several new laws that cracked down on drug users. He also created the Drug Enforcement Administration.
By 1973, about 300,000 people were being arrested every year under the law — the majority of whom were African-American.
