Dextromethorphan, or DXM, a common active ingredient found in many over-the-counter cough suppressant cold medicines, is used as a recreational drug and entheogen for its dissociative effects. It has almost no psychoactive effects at medically recommended doses. Dextromethorphan has powerful dissociative properties when administered in doses well above those considered therapeutic for cough suppression. Recreational use of DXM is sometimes referred to in slang form as "robo-tripping," whose prefix derives from the Robitussin brand name, or Triple Cs, which derives from the Coricidin brand. (The pills were printed with "CCC" for "Coricidin Cough and Cold.") However, this brand presents a danger when used at recreational doses due to the presence of chlorpheniramine.
