The active ingredient in Delsym Cough Suppressant is dextromethorphan, which enters the central nervous system and raises the threshold for coughing. It is found in many over the counter cough suppressants. At very high doses it can be used recreationally as a dissociative hallucinogenic. It has been reported to rarely lead to psychological dependence but is not physically addictive.
