This will have to be short. I feel the (US) government profits from court proceeds and that added wonderful benefit of putting druggies on a list they call probation. That beautiful Black List.... anyway. The capital gain of incarceration, which is highly profitable for states, accounts for an 85% lock-up rate for drug-related crimes. That type of revenue can not be generated by sales, taxes and other legal means. In short, they've done the math!
