"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."
"In 2013, the ACLU published a report titled "The War on Marijuana in Black and White". The report found that despite marijuana use being roughly equal between blacks and whites, blacks are 3.73 times as likely to be arrested for marijuana possession."
