Yes, I do often wonder how much the FDA can or will enforce. It doesn't bother me either way.
It bothers me--vaping is a great way to help people stop smoking and I'm furious that our country, our FDA and our legislators, are hell-bent on taking it away/making it prohibitively expensive/discouraging smokers from trying via their relentless attacks on vaping. I can't believe that this is happening here.
