I prefer the Darwin approach.
Legalize all drugs, make them free and readily available.
Dispensers on every corner for the really bad ones.
It would be hell for a year or three but Gump's law would trim the population of the worst among us.
It would also bankrupt the dealers and cartels.
No time and money wasted on trials, rehab, DEA and prisons.
Also would improve the gene pool a lot.
Can't see a downside.
