(San Francisco Department of Health | The Associated Press) This Aug. 8, 2016, photo released by the San Francisco Department of Health shows gummy ring candies served at a Quincea'era party in San Francisco. City health officials suspect the candies that sickened 19 people at a birthday party on Saturday, Aug. 6, 2016, contained edible marijuana. Final lab results weren't available Monday, but officials say some of the hospitalized patients tested positive for THC, the main psychoactive ingredient in marijuana.
