In this study, psychological functions and meanings of rewarding experience accompanied by the pleasure of addiction were reviewed through subject relations theory. To this end, the study looked at the similarities of rewarding experiences revealed in phenomenological rewarding experiences of methamphetamine and gambling addicts. The rewarding experiences can be described as the fusion experience in normal symbiotic phase in the psychological birth of an infant that Mahler suggested. The psychological fusion experience can appear not only in childhood but also in adulthood, and in Kohut’s theory, addiction could be redefined as a pathological fusion that constantly compensate for defects in self–development and ego–function development by compulsive ways. Finally, the study discussed roles of a church and Christian counseling intervention in order to support recovery of addicts in object relations theory with redefining the rewarding experience in addiction as a pathological fusion experience.
