Context and Objective: The Correctional Service of Canada (CSC) provides opioid agonist treatment (OAT) to federal inmates with opioid use disorder (OUD), including methadone, oral buprenorphine-naloxone (Suboxone®), or extended-release injectable buprenorphine (Sublocade®). OAT in correctional settings is linked to improved health and reduced criminal behavior post-release. However, documenting qualitative experiences is needed to contextualize better barriers and facilitators related to OAT maintenance. This presentation covers the second phase of a longitudinal qualitative cohort study, focusing on the period between two and six months post-release. This study explores the experiences of Quebec former inmates with OUD receiving OAT, specifically their life situation post-release, substance use, treatment and other services received. Methodology: Semi-structured interviews were conducted with 10 former inmates in the Spring and Summer of 2023. Thematic content analysis was used to identify and compare key themes and their underlying factors. Results: Participants' post-release experiences centered around three main life goals: 1) reintegrating into a stable and so-called "normal" life, 2) distancing themselves from substance use, and 3) accessing OAT and other medical or psychosocial services. Facilitators and barriers to these goals were categorized according to individual factors, pharmacological aspects of substances (OAT and drugs), social environment, and services or institutions. These life goals were interconnected, with overlapping factors influencing each other over time. Conclusion: The study highlights the challenges and opportunities faced by participants after their release. The findings offer valuable insights to inform policies and interventions aimed at improving the reintegration process and supporting individuals in achieving their goals related to OAT and substance use.
