It's in (I believe) path: the question was asked (and, yes, probably led) - I paraphrase: why do you use vaping products?Honestly, I don't think we KNOW this. I don't think we even know if "kids" are really even using flavors. I haven't looked into it, but the few things I have seen with teens vaping have been all about tricks, I've never heard a teen mention a flavor. Just like no one asked if they were using nicotine, no one asked if they were using flavors either. Granted, some undoubtedly are, but they could just as easily be vaping pure VG.
You're right though, the real question is whether or not vaping is a credible public health "threat," as opposed to just a "potential" one.
Flavors came back as the top answer. I don't know whether they asked about tricks, or whether responses were unprompted. Anyone?
In any case, why should we be surprised that kids say "flavors" when asked why? The reality is that there's another argument which is politically unpalatable and which not enough people are asking.
