Think tank retracts study on pot dispensaries

A respected think tank is now retracting its recent study that made shock waves by claiming crime increased in places where medical marijuana dispensaries have been forced to shut down.

The Rand Corporation says it forgot to include crimes reported by the Los Angeles police department. Last month's study included 1,200 other law enforcement agencies and concluded that. Dispensaries, with their surveillance cameras and guards, may help reduce crime in their neighborhoods.

Rand is apologizing and reviewing its research procedure.
