ABSTRACT Background Boxing Clever Cork is an interagency program for people who have experienced or are experiencing problematic substance use. It integrates a fitness program with education, with the aim of reducing harm and supporting addiction recovery in the lives of participants. The aim of this research was to evaluate the Cork iteration of Boxing Clever, which originated in Ballymun, Dublin. Methods A qualitative approach was taken to data collection, using the World Café 1 method along with one to one interviewing, and data was analyzed using thematic analysis. Results Research participants described feelings of vulnerability and isolation during the embryonic stages of sobriety. Boxing Clever Cork introduced structure and purpose into their lives and created a model of peer-to-peer support within a newly formed early recovery community. Challenges encountered included the diverse stages of recovery within the group, however, despite these challenges research participants felt it was important that people actively using substances continued to be included in future programs. Professionals were motivated through the principles of social inclusion. Conclusions Opportunities for development include community-based delivery, a peer mentorship model and provision of additional mental health supports.
