City code enforcement officers and police will no longer target medical marijuana dispensaries under a directive issued Friday by Mayor Bob Filner.

Filner, in letters to Kelly Broughton, director of the Development Services Department, which oversees code compliance, and San Diego police Chief William Landsdowne, also directed both of their departments "to stop sending dispensary code enforcement cases to the City Attorney's Office for prosecution."

"To be clear, if there are general code enforcement or health and safety issues arising from these businesses, you are expected to enforce those laws against these businesses in the same manner you would any other business," the mayor wrote.
