The Huffington Post did a good job yesterday reporting on the costs of the so-called “war on drugs:”

Despite an increased emphasis on treatment and prevention programs in recent years, the Obama administration in its 2013 budget still requested $25.6 billion in federal spending on the drug war. Of that, $15 billion would go to law enforcement, interdiction and international efforts.

The pro-reform Drug Policy Alliance estimates that when you combine state and local spending on everything from drug-related arrests to prison, the total cost adds up to at least $51 billion per year. Over four decades, the group says, American taxpayers have dished out $1 trillion on the drug war.
