This is a reversal of policy for the DOJ, who previously left medical marijuana dispensaries in California under the jurisdiction of the state.
The Huffington Post reports:
Despite a previous DoJ memo that targeting medical marijuana is an inefficient use of time and resources, this past Friday morning, four California-based U.S. Attorneys and their staffs gathered in front of Sacramento’s capitol building to announce an aggressive new crackdown on medical marijuana operations throughout the state — this one aimed at the landlords who manage buildings in which dispensaries operate.
Detailing an industry that has “swelled to include numerous drug-trafficking enterprises,” the federal officials warned they would be taking action against dozens of dispensaries they accused of abusing California’s medical marijuana laws.
