Many experts, including Attorney General Eric Holder, now recognize that the so-called “war on drugs” the nation has waged over the last three decades has been in many ways counterproductive, filling state and local prisons with hundreds of thousands of low-level, nonviolent drug offenders who then become a permanent drag on the economy when their criminal records prevent them from obtaining gainful employment on release.

The relentless focus on arresting and imprisoning people for possession of small amounts of marijuana has torn apart millions of minority and low-income families and shredded the social fabric of their communities.

America obviously can’t continue along that self-destructive path, but the drive for change will have to come from the states rather than from the federal government.  The Justice Department has now acknowledged that it needs to get out of the way so that can happen, and one can only hope the conversation about pot that ensues will produce a way out of the country’s current dilemma sooner rather than later.
