Smoking isnt good. Underage smoking vaprs is way higher than cigarettes and surveys indicate the candy flavors are the biggest motivator. It's also pretty wild how unregulated it is considering people are literally inhaling it, I mean you could pretty much put anything in there which is easy to build fear around.
But also, whatever, educate folks but not in favor of banning stuff, and they do probably provide benefits too for some people getting away from cigarettes, the problem is theres no way to really quantify that.
I suspect the ban is probably mostly supported and pushed by big tobacco trying to make it more regulated so that it's more difficult for small companies to compete in the same arena.
