This introductory course, from the The Homeless and Housing Resource Center (HHRC), provides foundational information about the neurobiology and prevalence of opioid use disorder (OUD), the whole-person care framework and best practices, treatment and recovery supports for OUD, and supporting housing stability for individuals with OUD. While the principles in this course apply broadly to best practices for working with individuals with SUD, the focus throughout will be on individuals who are experiencing homelessness and OUD.
