Oral Bacteria, Cannabis Use, and Thinking Skills in People with HIV
Investigating the effect of oral microbiome on cognition in HIV-infected chronic cannabis users
This research explores how bacteria in the mouth, combined with cannabis use, might affect thinking and memory in people living with HIV.

What this research studies
Many people with HIV use cannabis, and its impact on their thinking abilities and immune system is not fully understood, with reports varying widely. This project looks at specific bacteria in the mouth, like *Actinomyces species*, which are more common in chronic cannabis users and people with HIV. Researchers want to understand if these oral bacteria play a significant role in how HIV affects the brain and its thinking processes. They will study people with HIV who use cannabis and also use laboratory models to learn more about this connection.
Who could benefit from this research
Good fit: Ideal candidates would be individuals living with HIV who are chronic cannabis users.
Not a fit: Patients who do not have HIV or do not use cannabis would likely not directly benefit from this specific research.
Why it matters
Potential benefit: Understanding this connection could lead to new ways to protect or improve thinking skills for people with HIV who use cannabis.
How similar studies have performed: While the specific link between oral bacteria, cannabis, and cognition in HIV is a novel area, previous work has identified specific oral bacteria enriched in cannabis users and HIV-infected individuals.
