Addicts are often referred to as fiends, and although we use the word fiend ever so casually, the average person is clueless as to what the word actually means.
The dictionary defines the word fiend as a devil, a demon or evil spirit, which raises the question as to how exactly are devils, demons and evil spirits synonymous with the addict. Believe it or not these definitions arose from the idea that the addict is actually an incarnate demon, helplessly possessed by his own evil spirit called the fiend, who tempts him from within to postpone his resolve for recovery, and proceed to feed his insatiable appetite for drugs against his better judgment.
Hence, the reason why the relapse rate for addiction is so high, is because as demonically possessed souls, addicts are in need of an exorcism, rather than the ineffective methods of conventional treatment that fails to address the real issue.
In a serendipitous turn of events, the addict can now reference The Addiction Experience, where he is instructed by the master exorcist, from whom he receives the authority to cast out his inner demon, and get clean once and for all.
