New York Times reporter Eduardo Porter has a terrific column, Numbers Tell of Failure in Drug War, excoriating the stupidity and tragedy of the War on Drugs in the July 4 issue. Here are just a few tidbits:

When policy makers in Washington worry about Mexico these days, they think in terms of a handful of numbers: Mexico's 19,500 hectares devoted to poppy cultivation for heroin; its 17,500 hectares growing cannabis; the 95 percent of American cocaine imports brought by Mexican cartels through Mexico and Central America.

They are thinking about the wrong numbers. If there is one number that embodies the seemingly intractable challenge imposed by the illegal drug trade on the relationship between the United States and Mexico, it is $177.26. That is the retail price, according to Drug Enforcement Administration data, of one gram of pure cocaine from your typical local pusher. That is 74 percent cheaper than it was 30 years ago.

This number contains pretty much all you need to evaluate the Mexican and American governments' "war" to eradicate illegal drugs from the streets of the United States. They would do well to heed its message. What it says is that the struggle on which they have spent billions of dollars and lost tens of thousands of lives over the last four decades has failed. …

…conceived to eradicate the illegal drug market, the war on drugs cannot be won. Once they understand this, the Mexican and American governments may consider refocusing their strategies to take aim at what really matters: the health and security of their citizens, communities and nations.

Prices match supply with demand. If the supply of an illicit drug were to fall, say because the Drug Enforcement Administration stopped it from reaching the nation's shores, we should expect its price to go up.

That is not what happened with cocaine. Despite billions spent on measures from spraying coca fields high in the Andes to jailing local dealers in Miami or Washington, a gram of cocaine cost about 16 percent less last year than it did in 2001. The drop is similar for heroin and methamphetamine. The only drug that has not experienced a significant fall in price is marijuana.

And it's not as if we've lost our taste for the stuff, either. About 40 percent of high school seniors admit to having taken some illegal drug in the last year — up from 30 percent two decades ago, according to the Monitoring the Future survey, financed by the National Institute on Drug Abuse.

The use of hard drugs, meanwhile, has remained roughly stable over the last two decades, rising by a few percentage points in the 1990s and declining by a few percentage points over the last decade, with consumption patterns moving from one drug to another according to fashion and ease of purchase…..

Jeffrey Miron, an economist at Harvard who studies drug policy closely, has suggested that legalizing all illicit drugs would produce net benefits to the United States of some $65 billion a year, mostly by cutting public spending on enforcement as well as through reduced crime and corruption.
