The Symptoms of Drug Abuse and Drug Interventions

The physically and psychologically overwhelming nature of drug dependency leaves drug addicts regrettably ill-equipped to conduct an honest and objective evaluation of their own behavior. Again, drug addiction is a disease, one whose physiological and emotional roots literally “infect” drug addicts. Drug addiction is “drug addiction” precisely because it strips addicts of the ability to relate to anything other than themselves and their drug habits: An addict is blind, really, in the sense that he can’t see beyond his need to use drugs.
