I suspect you are right about the age division, but would love to see some real numbers and studies about each side. Every study I have seen about the youth pushes your sentiment that "entire high schools are getting addicted", but when you look at the questions, they are typically very misleading and something along the lines of "have you ever tried a vape".

OTOH, being older, I have never met someone who vapes that didn't smoke before, and know several smokers who quit and switched over.
