>But you simply can't definitively say something is damn near harmless relative to cigarettes when you don't actually know what harm it causes I totally get where you're coming from and am sympathetic to this argument, but I don't agree with it. We have learned a great deal from decades of research in to the harms of cigarette smoking, and have drawn some uncontroversial conclusions about why smoking causes so many health problems. We also can be reasonably sure that vaporizing nicotine does not create those same harmful conditions. I'm not saying anyone knows the long term implications of vaping, but "no one knows what will happen" is not a strong argument to me. As it stands, I think we have every reason to believe that smoking cigarettes is drastically more harmful than vaping.
