Darwin will take care of the rest.
Once all the druggies have gone to their just reward, the rest of us can live in peace.
The only thing worse than drug legalization is drug Prohibition.
Tyrannical contraband law will never solve such a problem; it will only invariably make it worse. We saw the same thing with alcohol (a drug worse than all other drugs combined).
The crusading prohibitionist mind, with its hysterical, self-assured embrace of overt Tyranny, is more of a threat than any drug.
Asset forfeiture, no-knock warrants, long prison sentences for non-criminals, destruction of the Fourth Amendment, corruption in law enforcement, black markets, violent crime: all are predictable corollaries of the Tyrannical War on Drugs.
Prohibitionism is the only "treatment" which is far worse than the problem it seeks to address!
Most substances of abuse are comparatively cheap to manufacture, particularly compared to the societal costs of the war on drugs and the parallel druggie war on the populace to plunder them for the drugs.
