Colleges and universities across the United States are recognizing the unique needs of students who have a history of substance use disorders. In order to meet the needs of these students, colleges and universities developed collegiate recovery programs (CRPs) or collegiate recovery communities (CRCs) to help students maintain their recovery and treatment goals, reach for academic success, build a network of social support, and plan for the future. Despite the rapid growth of CRPs/CRCs within the last two decades, there is limited research that explores the variations of social support between programs. At many colleges and universities, CRP/CRC members not only receive social support from staff members and fellow students in recovery, but also from students who identify as allies to the recovery movement. These students do not identify as in recovery from a substance use disorder themselves, but they have chosen to provide support to those in recovery in an effort to build a culture on campus that does not revolve around using alcohol and drugs. Research has not yet examined how members in recovery experience and view the involvement of their allied, non-recovering peers. To investigate the structure of peer support and ally involvement, this study interviewed CRP/CRC members who identified as being in recovery from substance use. These interviews with members in recovery explored experiences, perceptions, and expectations of allied members. Additionally, participants highlighted possible areas for adjusting or creating guidelines for programs involving ally members, which include suggestions within the areas of community involvement, social support, and overall helpful limitations. This information could serve as guidance for future programming as campuses search for ways to better serve their students in recovery.
