This thesis presents a theoretical overview of the impact of spirituality on the treatment of addiction as a psychiatric disorder and achieving complete recovery and resocialization and integration into the society of former addicts. Namely, spirituality as an all-encompassing reality has positive implications for all aspects of human life and one of them is mental health. And in the context of talking about mental health, spirituality has a great influence in the process of healing from addiction and achieving complete recovery which is manifested as a transformed life with new priorities and value system, new attitudes and a new angle of view of reality. Also, this recovery includes the experience of forgiveness and renewal of broken relationships, the meaning and purpose of life, as well as the experience of self-transcendence. The therapeutic community also plays an important role in the recovery process, while the addiction treatment process usually begins with hospital treatment. In the process of recovery through the therapeutic community and its program, the individual has the opportunity to acquire new knowledge, skills and abilities, as well as a new way of interacting through respect, taking responsibility for tasks set and taking on a role. But also after completing the program, the individual is prepared for better resocialization and integration into the wider social environment in which the former addict has a need to share everything he has received, learned and adopted as an act of gratitude.
