The Latest: Police probing likely pot candy eaten by kids

A special unit of the San Francisco Police Department is investigating how 19 people including a 6-year-old child could have eaten gummy candies at a birthday party that most likely were marijuana edibles.

Officer Grace Gatpandan said at a Monday news conference that the unit is interviewing people to see if the candies were intentionally placed at the party to target children, which would be a serious crime.

The patients' symptoms included a rapid heart rate, high blood pressure, dilated pupils, dizziness, light-headedness, nausea, lethargy and confusion.

San Francisco health officials suspect the gummy candies that sickened 19 people at a birthday party 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.

The patients' symptoms were consistent with the effects of edible cannabis, including rapid heart rate, high blood pressure, dilated pupils, dizziness, light-headedness, nausea, lethargy and confusion.
