All of the cases required hospitalization related to coughing up blood, blood in the urine, bloody nose, bleeding gums and other symptoms. Nine of the cases tested positive for brodifacoum, or rat poison, according to a statement from the Illinois Department of Public Health on Monday.
Now, state officials are working to identify any common synthetic cannabinoid products related to those cases and to determine where the products were obtained.
There are still many questions about the illnesses; officials are not aware what exactly caused the drug contamination, but investigators and toxicologists are continuing to evaluate.
“This is the first time we’ve seen an outbreak of this magnitude in the area,” Melaney Arnold, a spokeswoman for the Illinois Department of Public Health, said Monday.
“We’re working with numerous different partners across the city and state as we investigate this outbreak,” she said.
Synthetic cannabinoids are sold in convenience stores, gas stations, drug paraphernalia shops, novelty stores and even online.
Health officials warn that anyone who has a reaction to synthetic cannabinoids immediately should call 911 or be taken to an emergency department.
