Summary

This study tested a digital program designed to prevent teens from starting to misuse opioids. About 533 high school students who had never misused opioids but were at higher risk took part. The program aimed to increase their understanding of the serious risks of misusing prescription opioids and heroin. The main goal was to see if more teens in the program recognized the great risk of harm from these drugs after 3 months, compared to those who did not use the program.
