Thirteen people were taken to local hospitals Sunday afternoon for emergency treatment after suffering from an overdose of the synthetic drug Spice, according to the San Diego Fire-Rescue Department.
The 13, found throughout downtown, were suffering from vomiting and convulsions and displaying "extremely odd behavior," said Fire Capt. Joe Amador. Ages of those treated ranged from 13 to 45.
Police are attempting to track down all victims, witnesses and those selling the drug. The drug may have been sold in black packages with blue dragons on the side, they said.
Marketed in marijuana stores and online under names such as Mojo, Black Mamba and Annihilation, Spice is said to mimic the high produced by marijuana. But authorities have warned of the health dangers of the drug that mixes herbs and chemicals.
The U.S. Enforcement Administration has begun a nationwide crackdown on Spice.
