Summary

This study follows 32 people with cocaine use disorder as they go through detox. Researchers use wearable sleep monitors, questionnaires, and urine tests to track sleep quality and body rhythms during active use, early withdrawal, and late withdrawal. The goal is to understand how sleep changes and whether it can predict who stays drug-free.

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 could help identify sleep patterns that predict who will stay off cocaine long-term, potentially guiding future treatments.
What could go wrong
This is a small, early observational study with only 32 participants. It measures sleep, not a treatment, so it won't directly improve health. Results may not apply to everyone.
