Investigating how gut bacteria affect amphetamine abuse

Official title: The Role of Microbiome Composition in Amphetamine Abuse

Funded at University of Alabama at Birmingham · NIH-11090548 · Data updated 2026-11-12

This study is looking at how the bacteria in our gut might affect how our brains respond to amphetamines, which are sometimes used for attention issues but can also be misused, to help find new ways to treat substance use problems.

Who could benefit from this research

Could help

Ideal candidates for this research are individuals aged 21 and older who have a history of amphetamine use or abuse.

Less likely to help

Patients who do not use amphetamines or have no history of substance use disorders may not benefit from this research.

What this research studies

This research explores the relationship between gut microbiome composition and amphetamine abuse. It examines how changes in gut bacteria may influence the brain's response to amphetamines, which are often used to treat attention deficit disorders but can also be abused. The study will analyze the effects of microbial products, particularly short-chain fatty acids like butyrate, on behavior and dopamine levels in the brain. By understanding these interactions, the research aims to identify potential new treatment strategies for substance use disorders.

Why it matters

Potential benefit: If successful, this research could lead to innovative treatments that reduce the risk of amphetamine abuse by targeting gut microbiome health.

How similar studies have gone: Previous research has indicated that gut microbiome imbalances can influence substance use behaviors, suggesting that this approach may yield valuable insights.
