For a brief moment in 2009, medical marijuana advocates exhaled. A new President had taken office promising to call off the federal prosecutors in states that had legalized weed for the sick. Medical marijuana patients and the growing industry thought they were in the clear. But they weren’t. Two years later, the Obama Administration is cracking down on medical marijuana dispensaries and growers just as harshly as George W. Bush did. In 2011, the Department of Justice revised its guidance to U.S. Attorneys, allowing them to target any medical marijuana activity except for ill patients and their immediate caregivers.
