Only rich white people can afford cocaine it's also never the one you would expect could be using cocaine which is why "War on Drug" was designed to be racists in mind. I know several people who use drugs all of them are Caucasian, worked for respectable careers, makes respectable wages, and live in higher income neighborhood if you get to know them they're cocaine addict.

Illicit drugs are expensive especially the high quality versions from respected dealers and the reason I mentioned only rich white people can afford cocaine it's true. Also almost all of these dealers making bank are Caucasian you see them all the time in rough neighborhood driving nice cars.
