Who could benefit from this research

Could help

Individuals at risk of overdose who interact with or live in communities where overdose prevention programs operate.

Less likely to help

People not connected to or affected by overdose prevention services may see little direct benefit.

What this research studies

If funded, researchers at Brown University will examine how social networks surrounding people who use drugs shape engagement with overdose prevention programs, including naloxone access, testing, and social supports. The study will analyze real-world program data and may include interviews or surveys to understand network effects on service uptake. The goal is to identify network-based barriers and facilitators so programs can better reach people at risk of overdose.

Why it matters

Potential benefit: If successful, the findings could help communities tailor overdose prevention programs to better reach people who use drugs.

How similar studies have gone: Previous work has shown that social networks influence health behaviors, but this study explores network effects on overdose-program uptake specifically.
