Federal Drug Enforcement Administration agents raided Emmalyn’s California Cannabis Clinic at 1597 Howard Street in San Francisco’s South of Market district on the afternoon of Wednesday 25 March 2009.[1][2] The dispensary held a temporary permit from the city Department of Public Health and had served patients since before the city’s 2006 dispensary ordinance.[1][2] Agents removed bins of marijuana plants, growing equipment, cash and computers, and made no arrests.[1][2]

The raid came a week after US Attorney General Eric Holder signaled that the Obama administration would not prosecute dispensaries complying with state medical-marijuana law.[1][2] DEA Special Agent in Charge Anthony Williams said the investigation found suspected violations of federal and state law.[2] A city-government source said the action appeared prompted by alleged sales-tax improprieties, while clinic attorney Terence Hallinan, a former San Francisco district attorney, said he knew of no state or local violation by his client.[1][2] Supervisor Chris Daly, in whose district Emmalyn’s operated, condemned the use of force against patient access.[1]
