Acute intoxication caused by a synthetic cannabinoid in two adolescents.

Illicit drug use continues to be a common problem among pediatric patients. Daily marijuana use among high school seniors is currently at a 30-year high. Marijuana use in adults has rarely been associated with cardiovascular adverse effects, including hypertension, tachycardia, arrhythmia, and myocardial infarction. Recently, abuse of synthetic cannabinoids, such as the incense "K2" or "Spice," has been increasingly reported in the lay press and medical literature. Overdose and chronic use of these substances may cause adverse effects including altered mental status, tachycardia, and loss of consciousness. Overdoses in adult patients have been described; however, limited reports in the pediatric population have been documented. A recent case series describes myocardial infarctions in pediatric patients, associated with synthetic cannabinoid use. In this report, we describe two adolescent patients admitted after they inhaled "K2," resulting in loss of consciousness, tachycardia, and diffuse pain.
