To you they may seem ridiculous, but if they represent a sudden change from the way they were feeling, I can understand asking the question. The ones that I find more laughable are the ones that worry that something might not be up to an as yet undetermined pure-and-safe standard. For gawd's sake, they don't even know everything that's in what they've smoking for the last umpteen years. And now they get concerned about what they might be inhaling? It could be lawn-clipping-broth from the back yard and still be less toxic than a pack of cigarettes.
That is what I mean. Here are some of the chemical in ciggy smoke. I really can't see vaping being any worse than inhaling this little lot, can you?
