The National Health Care for the Homeless Council’s Substance Use Guidelines are brief substance-specific guidelines intended for use by anyone who is a consumer of services or a service provider working with people experiencing homelessness and people who use drugs.

The guidelines were developed with the help of national and community-based experts and made possible through funding from the US Health and Human Services Administration.

The guidelines can be used as individual documents or as a unified resource. Each guideline provides information on the substance covered, outlines how experiences of homelessness might impact experiences of use, access to treatment, and overall health, and provides harm reduction-based supports and resources that can be utilized by service providers across roles and settings.
