Opioid addiction is a widespread problem that social workers will undoubtedly face in practice. Curricular infusion is an approach that has gained recognition in social work education for integrating critical, contemporary topics into courses. This paper details a project that infused opioid addiction in baccalaureate of social work (BSW) courses, including human behavior in the social environment (HBSE), policy, and research. When implemented and evaluated, this effort was found to be beneficial to student learning and has implications for integrating this and other contemporary issues into the curriculum.
