A very large part of the prison population across the country comes from people convicted of a felony, given probation, and being kicked off of probation. The number 1 way to get kicked off probation is failing a drug test. The war on drugs led to the massive prison expansion since 1972 in the usa
And conveniently, mostly to the kind of communities like blacks and latinos more likely to use some cheapo drugs, and not to the kind of communities (basically rich white people) using the expensive shit (basically coke, which in the 70s and 80s was everywhere)...
