Friday marks the 40th anniversary of one of the biggest, most expensive, most destructive social policy experiments in American history: The war on drugs. On the morning of June 17, 1971, President Richard Nixon, speaking from the Briefing Room of the White House, declared: "America’s public enemy No. 1 in the United States is drug abuse. In order to fight and defeat this enemy, it is necessary to wage a new, all-out offensive. I have asked the Congress to provide the legislative authority and the funds to fuel this kind of an offensive. This will be a worldwide offensive dealing with the problems of sources of supply, as well as Americans who may be stationed abroad, wherever they are in the world. "

So began a war that has waxed and waned, ,sputtered and sprinted, until it became an unmitigated disaster, an abomination of justice and a self-perpetuating, trillion-dollar economy of wasted human capital, ruined lives and decimated communities. Since 1971, more than 40 million arrests have been conducted for drug-related offenses. And no group has been more targeted and suffered more damage than the black community. As the American Civil Liberties Union pointed out last week, "The racial disparities are staggering: despite the fact that whites engage in drug offenses at a higher rate than African-Americans, African-Americans are incarcerated for drug offenses at a rate that is: 10 times greater than that of whites. "

An effort meant to save us from a form of moral decay became its own insidious brand of moral perversion-turning people who should have been patients into prisoners, criminalizing victimless behavior, targeting those whose first offense was entering the world wrapped in the wrong skin. It feeds our overwhelming thirst for punishment.

Last week, the Report of the Global Commission on Drug Policy, a 19-member commission that included Kofi Annan, a former U. N. secretary general, declared that: "The global war on drugs has failed, with devastating consequences for individuals and societies around the world. Fifty years after the initiation of the U.N. Single Convention on Narcotic Drugs, and 40 years after President Nixon launched the U. S. government’s war on drugs, fundamental reforms in national and global drug control policies are urgently needed. "

The White House immediately shot back: no dice. The Obama administration presented a collection of statistics that compared current drug use and demand with the peak of the late 1970s, although a direct correlation between those declines and the drug war are highly debatable. In doing so, it completely sidestepped the human, economic and societal toll of the mass imprisonment of millions of Americans, many for simple possession.

No need to put a human face on 40 years of folly when you can wrap up its inefficacy in a patchwork quilt of self-serving statistics.
