The purpose of this thesis was to examine how people who have lived at Hammarbakkens Health and Rehabilitation clinic experienced the CRA treatment they received for their addiction and if they feel that the treatment have had any impact on their drug and/or alcohol habits. Through a qualitative approach and semi-structured interviews, answers to the following questions were sought: Do they feel that the treatment has contributed to a change in their lives, and if so, how? What do they experience as negative/positive about the treatment? Have they been able to learn anything from the treatment? The theoretical background is theories in learning psychology. Six people were interviewed, two women and four men, between the ages of 29 and 61. The results showed that the treatment generally contributed to a change in the lives of the interviewed in terms of less days in abuse. Through the CRA treatment they gained greater insight into their own behavior and the consequences of their abuse. According to the interviewed the most positive with the treatment was the staff's positive attitude and that the treatment had provided opportunities for reflection. The negative was not enough time in treatment and that it was perceived as superficial.
