Official title: Heavy cannabis use, neurocognition and PrEP care engagement among young people

Funded at University of Chicago · NIH-11405057 · Data updated 2026-11-12

A two-phase study will look at how heavy cannabis use affects brain function and how that relates to HIV prevention and PrEP engagement among young people in Chicago.

Who could benefit from this research

Could help

Young people who use cannabis heavily and are involved with HIV prevention programs in Chicago.

Less likely to help

People outside the study setting or those who do not use cannabis heavily may see limited direct benefit.

What this research studies

This project will examine whether heavy cannabis use alters brain systems for risk/reward and executive function in young people, and how these changes relate to PrEP use and HIV prevention behaviors. Researchers will combine cognitive testing, brain function insights, and behavioral data within existing HIV prevention programs in Chicago. The goal is to understand if neurocognitive effects of cannabis influence decisions about HIV testing and starting or staying on PrEP. The work will use data from participants in local health department programs to identify mechanisms and potential points for intervention.

Why it matters

Potential benefit: If successful, the findings could inform targeted strategies to improve PrEP engagement among young cannabis users.

How similar studies have gone: Prior work suggests a link between cannabis use and cognitive function and HIV prevention behaviors, but the integrated mechanism and PrEP engagement focus are relatively novel.
