Summary

This study compares two methods for getting rid of leftover opioid painkillers after surgery: a special pouch that deactivates the drugs, and a prepaid envelope to mail them back. Researchers will track which method more people actually use. The goal is to find a simple, effective way to keep unused opioids out of homes and the environment.
