This guide highlights strategies for behavioral health and housing providers to conduct outreach and engage with individuals experiencing homelessness, initiate use of behavioral health treatment as they wait to receive stable housing and retain them in their recovery efforts once housed.

The goal of this guide is to review the literature on treating substance misuse and substance use disorders in the context of first-episode psychosis, distill the research into recommendations for practice, and provide examples of the ways that these recommendations can be implemented by first-episode psychosis treatment programs.
