Federal agents raid San Diego marijuana clinics

Federal anti-drug agents have raided at least four San Diego medical marijuana clinics and arrested 12 people accused of selling pot illegally.

A spokeswoman for the U.S. attorney's office in San Diego, Debra Hartman, says Drug Enforcement Administration agents served the search warrants Friday morning.

She says the suspects will be arraigned Monday on charges of conspiracy to distribute and manufacture marijuana and conspiracy to launder drug proceeds. She declined to comment further.

Kris Hermes of Americans for Safe Access says the raids undermine local efforts to regulate the clinics.

San Diego County is working on a new ordinance to crack down on the dispensaries. Federal agents have raided numerous clinics over the years.
