Summary

This study follows 1600 adults with opioid use disorder over the long term by collecting monthly online surveys and yearly phone interviews. Researchers will track substance use, mental health, treatment involvement, and daily functioning. The goal is to better understand how people recover from opioid addiction, which could lead to improved interventions and support.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this study could reveal key patterns in long-term recovery from opioid use disorder, helping to design better treatments and support programs.
What could go wrong
This is an observational study, not a treatment trial, so it won't directly test any new therapy. Results depend on participants staying engaged over time, and findings may not apply to everyone with opioid use disorder.
