Monitoring trends in dextromethorphan abuse using the National Poison Data System: 2000-2010.

Context: Dextromethorphan (DXM) abuse persists among US youth and should be closely monitored because of the risks of severe medical complications, addiction, and psychiatric sequelae. Prior investigations have demonstrated DXM to be an emerging drug of abuse with increasing national prevalence through 2004.

Objective: To extend existing substance abuse survey results by describing demographic, geographic, product, and outcome trends in medically significant DXM abuse cases (those reported to US poison centers).
