throughout most of the 80s the policy was 'do as i say, not as i do' as far as I can tell. with the government simultaneously financing the contras and fueling a drug epidemic. in the 90s we saw 3 strikes and a nearly terminal myopic perspective that branded drug abuse victims the same as Hillary Clintons "superpredators" and other violent felons. Today the US has become the nation with the greatest number of citizens incarcerated, thanks in part to this endless drug war. Conversely, the opioid crisis in the US has been recognized but almost no convictions of drug executives have taken place for their role in fueling it. It feels similar to the housing crisis.
Its also difficult to see the drug war as anything but a proxy for placating voter bases after the 1964 Civil Rights amendment. Michelle Alexanders 'the new jim crow' goes into detail regarding this.
I hope 2018 continues the sobering trend of abolishing mandatory minimums and decriminalizing marijuana, a recreational narcotic less dangerous than Alcohol yet one which has managed to become more regulated than methamphetamine.
