They left out some of the worst of it. (Edited to acknowledge that's arguably an unfair statement for me to make. The article is specifically about the term marijuana, so what I added below is arguably out of scope for what they were reporting. Still, Ainslinger was off his fucking rocker on this shit. This isn't even the only eyebrow raising quote from him on the topic.)
Harry J Ainslinger was the first head of the Federal Bureau of Narcotics, predecessor to the DEA. Here's one of his quotes on the topic:
There are 100,000 total marijuana smokers in the US, and most are Negroes, Hispanics, Filipinos and entertainers. Their Satanic music, jazz and swing, result from marijuana usage. This marijuana causes white women to seek sexual relations with Negroes, entertainers and any others.
That was back in the early 20th century.
More recently we have this from Nixon's domestic policy head:
In a 1994 interview, Mr. Ehrlichman said, “You want to know what this was really all about?” He went on:
“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.”
The war on drugs has always been racist. Crack cocaine is an even more clear example.
