Los Angeles city officials have widened their campaign against illegal medical marijuana dispensaries, warning an additional 60 stores that they must shut down immediately. Los Angeles city officials have widened their campaign against illegal medical marijuana dispensaries, warning an additional 60 stores that they must shut down immediately.

The new letters went out earlier this week about two weeks after the city attorney's office notified the operators and landlords of another 141 pot shops that they must close. The letters warn that the city could sue violators, seek financial penalties and “padlock the property.”

Asha Greenberg, the assistant city attorney who oversees the enforcement efforts, said that city employees checked every one of the newly notified locations to be certain the businesses were open.

“These were locations that we were unclear about,” she said. She added, however, that the office has not determined whether all those stores are selling marijuana.

The city’s letter asks for a response. So far, Greenberg said, the city attorney’s office has received information on two dozen locations. At 11, the dispensaries are closed. At six, owners said they were acting to close them. At another six, the dispensaries are still open. And at one site, the business has denied that it is a medical marijuana dispensary.
