California -- In response to a question at a Wednesday news conference, US Attorney General Eric Holder said the Justice Department will no longer raid medical marijuana dispensaries in states where they are legal under state law. The announcement marks the fulfillment of a President Obama campaign promise, and it marks the end of 13 years of stubborn federal resistance to state medical marijuana programs. DEA raids of medical marijuana facilities in California continued after Obama's election in November and even after his inauguration last month. Holder was asked if those raids represented Justice Department policy under the new administration. "Shortly after the inauguration there were raids on California medical marijuana dispensaries. Do you expect these to continue?" the reporter asked, noting that the president had promised to end the raids in the campaign. "No," Holder responded. "What the president said during the campaign, you'll be surprised to know, will be consistent with what we'll be doing in law enforcement. He was my boss during the campaign. He is formally and technically and by law my boss now. What he said during the campaign is now American policy." Nearly 75 million Americans live in the 13 states where medical marijuana is legal. But because of the federal government's refusal to recognize state medical marijuana laws, dozens of dispensaries in California have been raided by the DEA, typically in over-the-top paramilitary-style operations. More than a hundred people are facing prosecution, sentencing, or are already imprisoned under draconian federal marijuana laws because of their roles in operating dispensaries. "There has been a lot of collateral damage in the federal campaign against medical marijuana patients," said Steph Sherer, medical marijuana patient and executive director of Americans for Safe Access (ASA), the nation's largest medical cannabis advocacy organization. "We need to stop the prosecutions, bring the prisoners home, and begin working to eliminate the conflict between state and federal medical marijuana laws." At an ASA press conference hastily called for Thursday afternoon, Sherer elaborated. "I'm overjoyed to finally hold a press conference with some great news," she said. "Today is a victory and a huge step forward in what has been at times a cruel and tragic period. My outrage over the raids was shared by millions of Americans, and now our collective voice has been heard in Washington. We look forward to working with the Obama administration to harmonize the conflicts with state laws once and for all." But for some patients and dispensary operators, the damage has already been done. Larry Epstein operates a legal medical cannabis dispensing collective in Marina Del Rey, California, that was raided by the Drug Enforcement Administration (DEA) on February 4, despite President Obama's statements on the campaign trail indicating a change in federal policy. "We had been operating as a legitimate cooperative dispensary per California law for a number of years," said Epstein. "But the DEA came in here as if we were operating an illegal drug cartel. They stole all our property, all our product, and froze our bank accounts. Now, we can't pay our taxes; that's part of what they stole. It's devastating when they do those types of actions, never mind the hundreds of patients who rely on our facility to get their medicine."
