RE: Lighten up, jeez. I was less defensive than this when I smoked ciggies...
That may be because when you smoke and people tell you its really bad for you and you're probably going to die, they're actually repeating scientifically verified facts. So you can't really get defensive can you?
Its slightly different when people are repeating bad things about vaping that they read in The Sun, who got it from a research paper "sponsored" by a tobacco company, that got shot down with real science almost instantly.
