First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study aims to understand why some people with opioid use disorder have more severe addiction than others. Researchers will collect blood, saliva, and hair samples from 350 participants and combine that with detailed interviews about their social and mental health. The goal is to find biological markers that, together with life experiences, could better predict how the disease progresses.

What this could lead to
If successful, this could lead to better ways to measure opioid addiction severity and predict its course, helping tailor treatments.
What could go wrong
This is an observational study, not testing a treatment. It may not directly improve patient outcomes, and results may not apply to all opioid users.
