This research is being performed to understand the role of music in people's opioid cravings, opioid use, and recovery. Music affects individuals in so many ways, and can trigger strong good and bad emotions. People listen when they are sad and want to feel happy, when they are with friends, when they exercise, and when they just want to pass the time. However, it is not known what role music plays in adding to or taking away cravings, and the role it has in drug use and addiction. In this study, the researchers want to learn if music can reduce cues that lead to cravings for opioids. The researchers also want to learn about subjects' relationship to music and how it contributes to drug use, recovery, and their life overall.
