Summary

This study looks at whether a program called 'CATCH My Breath' can stop high school students from starting to vape. About 5,600 students from 28 schools in Ontario, Canada will take part. They will get two 60-minute lessons about the risks of vaping and how to say no. Researchers will check if fewer students start vaping after the program compared to students who did not get it.
