I have heard a few people on ECF claim they have got less colds because of vaping. I'm a little skeptical of that. But Wikipedia does say a study found PG to be a good air-germicide and could do just such things in mice. Might it also help kill germs that cause bad breath, cavities, and other maladies? It would be fascinating to see a small study done on vapers vs controls to see who had more colds, cavities, and other illnesses per year.
I'm sure there are some down-sides to vaping we just don't know about yet. But wouldn't it be great if the upsides were bigger! Thoughts?
