Adults experiencing severe and multiple disadvantage homelessness often face challenges around problematic substance use, mental health issues, and as victims of crime. Several different interventions are often used to address problematic substance use, ranging from abstinence-based (where the individual is required to abstain from using throughout the intervention) through to harm reduction (aimed at reducing the harms associated with use, rather than the substance use itself).

This systematic review will assess the extant evidence on the effectiveness of these interventions, aimed at providing evidence of what works for policy makers, commissioners, and providers.
