Examining the relationship between homelessness and drug use patterns among people on probation or parole
Official title: A Longitudinal Qualitative Study of Fentanyl-Stimulant Polysubstance Use Among People Experiencing Homelessness (Administrative supplement)
Funded at Yale University · NIH-10841820 · Data updated 2026-11-12
This study looks at how being on probation or parole impacts drug use, especially fentanyl and stimulants, among people who are homeless, focusing on the struggles they face after being in jail and how it affects their chances of overdose, particularly for those from racially minoritized groups.

Who could benefit from this research
✓Could help
Ideal candidates for this research are individuals experiencing homelessness who are currently on probation or parole and use fentanyl and stimulants.
✕Less likely to help
Patients who are not experiencing homelessness or are not involved in the criminal justice system may not benefit from this research.
What this research studies
This research investigates how community supervision, such as probation and parole, affects the patterns of drug use, particularly fentanyl and stimulants, among individuals experiencing homelessness. It aims to understand the vulnerabilities to overdose that arise during and after incarceration, especially for those who are racially minoritized. By conducting qualitative interviews, the study will explore the challenges these individuals face in accessing housing and treatment services post-release. The findings could inform policies and programs aimed at improving support for this population.
Why it matters
Potential benefit: If successful, this research could lead to improved treatment and support services for homeless individuals struggling with polysubstance use, ultimately reducing overdose risks.
How similar studies have gone: While there is ongoing research into drug use and homelessness, this specific focus on community supervision and its impact on overdose vulnerability is relatively novel.
