Do you have sources for that, rudy2010? I know the County Sheriff' narc squad raided some dispensaries in December of last year, but those raids have stopped with the election of a new DA and clarification of tax laws.

Moreover, the raids did not, as far as I can find on the web, involve Federal agents, which was my point. The California-NORML website lists just two federal dispensary raids in the past year-plus. One of a grow op with ~500 plants, and the other of a guy who is accused of using his SoCal dispensary as a front to smuggle in Mexican pot by the ton.

I know of no Federal effort to usurp California-legal MMJ dispensaries, but would be interested to hear if there's been any recent change to their operations.
