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.
