We write to express our concern with the recent activity by the Department of Justice against legitimate medical cannabis dispensaries in California that are operating legally under state law. As you know, in October of 2009, Attorney General Eric Holder issued formal guidelines for federal prosecutors in states that have enacted laws authorizing the use of cannabis for medical purposes. The guidelines were spelled out in a memo to United States Attorneys from then Deputy Attorney General David Ogden, saying in part that the Attorneys should not focus federal resources in their state “on individuals whose actions are in clear and unambiguous compliance with existing state laws providing for the medical use of marijuana.”
