An interesting article on the war on drugs from Rolling Stone
"All told, the United States has spent an estimated $500 billion to fight drugs - with very little to show for it. Cocaine is now as cheap as it was when Escobar died and more heavily used. Methamphetamine, barely a presence in 1993, is now used by 1.5 million Americans and may be more addictive than crack. We have nearly 500,000 people behind bars for drug crimes - a twelvefold increase since 1980 - with no discernible effect on the drug traffic. Virtually the only success the government can claim is the decline in the number of Americans who smoke marijuana - and even on that count, it is not clear that federal prevention programs are responsible."
