The aim of this paper is to investigate whether and how faith, and its practice through prayer and/or other religious aspects, has had an impact on the rehabilitation journey of addicts. It is widely known that in various therapeutic communities, addicts undergoing rehabilitation have found meaning in prayer and faith, regardless of whether they are believers, atheists, or are newly approaching faith. The first part of the paper will focus on the phenomenon of addiction and the role of faith through a review of previous research. It will then examine how and in what ways faith has influenced the rehabilitation of addicts, at which stage it has been most helpful, and how they have embraced it. The second part of the paper will consider the outcomes of the influence of faith, the changes experienced, the benefits incorporated into the lives of addicts, the lessons learned from faith, and its application in their daily lives after leaving the community. It will present the perspective of recovery through the acceptance and practice of religious philosophy and daily rituals. For this study, a qualitative methodology has been chosen. The participants of the research are drug addicts who are users of therapeutic communities where faith practice is an integral part of the rehabilitation program, and who voluntarily agree to participate. The data will be collected through interviews/group interviews. A semi-structured interview guide will be developed to thematically cover areas such as addiction, recovery, the roles and significance of faith, the role of faith in pre-addiction life, the influence of faith on daily life in the community, recovery, and preparation for reintegration. The interpretation of the results will maintain a user perspective, be sensitive to details, and focus on analyzing the significance of faith in addicts' efforts to avoid relapse.
