The War on Drugs has failed.

People recovering from drug and alcohol addiction are fond of defining insanity as trying the same thing over and over again and expecting a different result. By that standard, American policy toward mind-altering substances looks awfully familiar. The nation tried Prohibition once, with alcohol. Result: abject failure, rampant organized crime, and little lasting effect on consumption or addiction. In fact, Prohibition actually encouraged the use of harder spirits, since bootleggers could smuggle more alcohol in a car full of liquor than a car full of beer.

Alcohol prohibition lasted only a few years. The war on drugs has lasted for decades, and for the most part has consisted of only one solution, over and over: criminalization and imprisonment. Nearly 2 million people are arrested each year for drug offenses and a half-million are currently serving time on drug charges. Yet when stiffer sentences fail to produce the desired results, drug prohibitionists insist the penalties just aren’t harsh enough. They resemble the carpenter who complained that he had cut a board three times and it was still too short.
