Dr. Bowler: Whether or not e-cigarettes help people quit smoking is debatable. The definitive studies haven't been done yet, in my opinion. Our research on e-cigarettes in an older COPD population found that there was no benefit to smoking cessation and potentially higher nicotine use in the patients who used e-cigarettes.

Dr. Ylioja: So the My Life, My Quit program is really innovative in adapting our standard program for quit plans to work with teens. It's one of the first in the nation to really address the vaping epidemic, to help teens who are looking for help to quit.
