Dextromethorphan (DXM)
Dextromethorphan (DXM) is the active ingredient in nonprescription cough and cold medicines. Those products are safe when taken as recommended, but very large doses can produce euphoria and impaired judgment -- as well as nausea and vomiting, loss of coordination, increased heart rate and blood pressure, and brain damage due to a combination of DXM and decongestants often found in the medication, NIDA says.
DXM's street names include "Orange Crush," "Triple Cs," "Dex," and "Robo."
