Cocaine, AK-47 Seized at LA 'Pot Clinic' Probe launched after 'hit' at medical marijuana 'healing center' By Mary Papenfuss, Newser User Posted Aug 5, 2011 1:42 PM CDT 12 comments Comments An assault rifle like the one authorities say they seized at the White Oak Healing Center. (?gcfairch) (Newser) – Turns out one medical marijuana dispensary in Los Angeles wasn't so chill. A police raid of the place netted 9 kilos of cocaine, oxycodone, an AK-47 assault rifle and other guns, and 300 pot plants, according to authorities. An investigation of the White Oak Healing Center was launched last year after a fatal shooting at the center that looked like an "organied-crime-style hit," police told the Los Angeles Times. Six people have been busted for allegedly operating a drug ring between LA and Cleveland.
