Thousands of youth participate in residential substance abuse treatment each year. After completing treatment, many of these youth return to school. This study analyzed the process of substance abuse treatment at the Generations Youth Program, and identified opportunities for collaboration with school health personnel. A qualitative case study design was employed. Analysis of the treatment process revealed the primary goal of treatment was to assist youth in developing a belief in their ability to remain sober. This goal was achieved through a peer support network, development of self‐control, and acquisition of treatment knowledge. Youth who develop these skills are successfully discharged from treatment and return to home and school. Opportunities exist for collaboration between school health and substance abuse treatment personnel to enable discharged youth to remain drug free.
