Pan-London Substance Misuse Programme

About this programme

There is strong evidence that people who sleep rough experience some of the starkest health inequalities in London. The average age of death of a person who sleeps rough in England is under 50 years old. People who sleep rough also experience higher levels of multiple, complex co-morbidities than other groups including substance misuse and physical and mental health problems. Their lack of stable accommodation is a further barrier to engagement with treatment and healthcare which in turn creates a revolving door of homelessness, addiction, ill health and early death.

The Pan-London Substance Misuse Programme is funded by the Department of Health and Social Care for SSMT&RG and Department of Levelling Up, Communities and House (DLUCH) for Rough Sleeping Drug and Alcohol Treatment and Recovery Grant, in partnership with the Office for Health Improvement and Disparities, the Greater London Authority, and London boroughs.

Provided by Phoenix Futures, the Regional Homeless Engagement Substances Team (RhEST) works across London and alongside local community substance misuse teams to support people who sleep rough, or at risk of sleeping rough, to initially engage or re-engage with community substance misuse treatment services.
