Cannabis use was revealed in this study as a support for navigating occupational routines and enhancing occupational repertoires and engagement, feelings of belonging, and collective user identities. As such, substance abuse treatment practices, including those provided by occupational therapists, should recognize the potential significance of cannabis use within people's lives. Using a harm reduction approach, occupational therapists can acknowledge the ways in which clients use cannabis to manage their daily routines, while also focusing on supporting clients to reduce the ill-effects of cannabis. As individuals become more engaged in occupations that are significant in their lives, their need for and meaning of cannabis use may change leading to a possible reduction in its use and a shift in their identity construction.
