The gummy rings that sickened 19 people — including a 6-year-old — at a quinceañera in the Mission District were laced with pot, the San Francisco Public Health Department announced Monday, after a dozen patients tested positive for the main psychoactive ingredient in marijuana.
Spokeswoman Rachel Kagan said that the final lab tests on the gummy rings have not yet come back yet from Zuckerberg San Francisco General Hospital. But she said that 12 of the 19 people hospitalized after the party at the Women's Building on 18th Street had THC, or tetrahydrocannabinol, in their systems.
All of the 19 patients were discharged by Monday morning, officials added. The patients ranged in age from 6 to 18, doctors said. It's unclear if the birthday girl was a patient or not.
Dr. Tomas Aragon said they suffered from rapid heart rates, high blood pressure, dilated pupils, dizziness, light-headedness, nausea, lethargy and confusion.
Aragon and others are now trying to figure out how the candies got to the party, catered by an Oakland company. “The question remains, where did the candies come from?” said Aragon. “We are working with the catering company and our colleagues in Alameda to find out.” It's also quite possible a guest brought the candies to the party.
The catering company was not named, but it was revealed that the food was prepared at La Placita, a community kitchen in Oakland. Officials with the Alameda County Health Department inspected the kitchen and did not find any evidence cannibis was used there.
Aragon urged people to be very careful with "edibles," especially when the drugs are contained in bright-colored candies and passed around at family parties where young children and teenagers are in attendance.
“A situation like this, where they were consumed by unsuspecting people, and many children, is greatly concerning,” Aragon said.
Paramedics and firefighters raced to the quinceañera in San Francisco on Saturday night, where a 15-year-old girl was feted - a major rite of passage in the Latino community.
Security guard Raul Hernandez recalled how the party got chaotic and people got violently ill. He called 911 and recounted how scary it was. Some guests left foaming at the mouth.
"It was just one after another and another," Hernandez said. "A gentleman was holding his chest. The young lady, she couldn’t talk and was gasping for air."
