(HealthDay News) – Smoking synthetic versions of marijuana is landing some teens in the emergency room complaining of restlessness, agitation, and diaphoresis.

Joanna Cohen, MD, of the Children’s National Medical Center in Washington, DC, and colleagues report three case studies of patients presenting to the emergency department with signs and symptoms of intoxication.

The researchers note that each of the three teens reported smoking “K2” or “Spice.” One case arrived in a catatonic state, not responding to verbal or painful stimuli and unable to speak. Following 50mg of intravenous (IV) diphenhydramine and two doses of lorazepam 2mg IV, she regained motor and verbal functions. A second case arrived in the emergency department uncooperative, restless, and aggressive with diaphoresis. Following a dose of lorazepam 2mg IV and 50mg diphenhydramine IV, he returned to baseline. These two cases also presented with sinus tachycardia. The third case arrived agitated, appeared dystonic, and was dysarthric with pressured speech. After he received a normal saline bolus of 1,000mL and 4mg of lorazepam IV he returned to baseline neurologic status.

“Synthetic cannabinoid products often contain other active and inactive ingredients, which makes identifying the specific agent as the cause of the presenting symptoms difficult,” the authors write.
