Los Angeles city prosecutors are sending letters to 439 medical marijuana dispensaries warning them that they must shut down by June 7, when an ordinance to control pot shops will finally take effect after years of debate and delay.

Frank Mateljan, spokesman for the city attorney’s office, said the Police Department and city building inspectors compiled the list of illegal dispensaries. “We’re not saying we have them all,” he said. “This is the initial blanketing of locations that we are aware of at this time.”
