In It’s Just Cough Medicine” – Think Again!, addiction medicine expert witness Shannon C. Miller, M.D., FASAM, FAPA, CMRO, describes the abuse of OTC cough suppressants.
Dextromethorphan or DXM is a semisynthetic narcotic related to opium and found in many over-the-counter cough suppressants in the United States and most countries. DXM is contained in any drug whose name includes “DM” or “Tuss.” The drug comes in various forms. Most common are cough suppressants in caplet or liquid form, including Corcidin, Robitussin, Vicks Formula 44, Drixoral, and several generic brands. (A caution: Not all medicines under these brands contain the drug since most brands put out several formulations. Look on the label for “DM,” “Tuss,” or “Maximum Strength.”)…
DXM is related to opiates in its make-up, and it produces mind-altering highs. Misuse of the drug creates both depressant and mild hallucinogenic effects. It also acts as a dissociative anesthetic, similar to PCP and ketamine.
