Summary

This study aims to create a large data repository by collecting smartphone data and daily surveys from 10,000 adults who use alcohol or drugs. Participants will use an app that tracks phone activity and location, and answer short surveys about mood and substance use. The goal is to help researchers learn why people drop out of treatment or return to substance use, with the hope of improving future care.
