Drug Addiction and Treatment

Drug Addiction Introduction It is often heard about a drug problem on television and other media. Drug addiction is a progressive chronic disease caused by the use of narcotic substances. A main symptom of addiction is the occurrence of withdrawal symptoms as a consequence of the presence of the physical dependence on a particular substance. Wilson and Kolander (2011) state that drug abuse generally refers to chronic, excessive use of drug, such that physical or other personal harm is very likely to occur.
