37 Synthetic Cannabinoids What are they? What are the effects on people?

38 Synthetic Cannabinoids

39 Synthetic Cannabinoids: MPC YearTotal Cases Deaths *

40 Synthetic Cannabinoids: Effects Altered mental status Paranoia Psychosis Seizures Tachycardia Hypertension Nausea and vomiting Loss of consciousness Acute pain Hypokalemia Acute kidney injury Bhanushali GK, Jain G, Fatima H, et al.
