Can a breathing monitor help break Addiction's grip?

This small pilot study is testing whether a daily breathing exercise program, guided by a portable heart rate monitor, is practical and helpful for adults in a residential treatment program for opioid addiction. The main goal is to see if participants can stick with the program and whether it might help them manage stress, emotions, and drug cravings. The study will enroll 24 people to try the breathing exercises for about three weeks and track their experiences.
