Opioid Adherence and Support Through Innovative Texting Strategies

The goal of this clinical trial is to examine the effects of reminder and mindfulness text messages on medication adherence and managing craving, pain, and withdrawal symptoms in people taking medications for opioid use disorder through assessment questions collected twice daily during the course of treatment. The main questions it aims to answer are: 1. Do daily medication reminder text messages increase medication adherence for people taking medications for opioid use disorder? 2. To what extent do people engage with the daily mindfulness messages? 3. What impact does daily mindfulness text message quantity have on craving, pain, forgetfulness, and withdrawal symptoms? Participants will: 1. Receive daily medication reminder text messages for at least 24 weeks (i.e., 6 months) 2. Receive up to 6 mindfulness messages per day for 4 weeks (i.e., 1 month) 3. Answer daily questions twice a day during the 4 weeks of mindfulness messages 4. Answer questions about the study when enrolling, at the end of the 4 weeks of mindfulness messages, and at 4 and 16 weeks after the end of the mindfulness messages
