Focus on Adolescent Use of Club Drugs and "Other" Substances.

Club drugs and "other" abusable substances are briefly overviewed as a reminder about the wide variety of known and unknown substances used by adolescents, the high potential for direct and interactive substance use effects to manifest acutely and chronically, and the vigilance needed to anticipate and recognize the new effects and drug-drug interactions arising as novel substances continue to be custom "designed," manufactured, and marketed to meet substance use trends. This article discusses dextromethorphan, flunitrazepam (Rohypnol), gamma-hydroxybutyrate, inhalants, ketamine, lysergic acid diethylamide, methylenedioxymethamphetamine, phencyclidine, Salvia divinorum (salvia), synthetic cannabinoids, and synthetic cathinones (bath salts).
