Who could benefit from this research

Could help

Adults with opioid use disorder, with or without heavy alcohol use, who can complete pain testing and alcohol sessions.

Less likely to help

Individuals without either opioid use disorder or problematic alcohol use are unlikely to benefit.

What this research studies

This project will compare pain responses and how alcohol affects pain relief in three groups: people with opioid use disorder who drink heavily, people with opioid use disorder who don’t drink heavily, and people who drink heavily but don’t have opioid use disorder. Researchers will measure pain sensitivity when sober and after alcohol intake to see if pain signals or alcohol’s analgesic effects help drive heavy drinking. The study will use a combination of controlled tasks and standardized pain and alcohol tests to explore potential mechanisms. The goal is to identify factors that could be targeted to reduce co-use and improve treatment outcomes for OUD and AUD.

Why it matters

Potential benefit: If successful, findings could guide new approaches to reduce harmful alcohol use and improve treatment for people with opioid use disorder.

How similar studies have gone: Prior work has suggested a link between pain sensitivity and substance use, but direct testing of this reinforcement model in this population is novel.
