Once considered the new frontier of drugs and drug trafficking, synthetic cannabinoids have been around for years now and they’re becoming increasingly dangerous. More recently, authorities say dozens of overdoses in Connecticut occurred due to a drug called K-2 that was possibly laced with fentanyl.  

Authorities in Illinois are keeping an eye out for synthetic cannabinoids, which recently killed three people and caused severe bleeding in more than 100 others in the Chicago and Peoria areas.
