There are MANY articles out there discussing the relative benefits of gaping to smoking and most agree that it's safer to some degree. What I'd like to know is what are the absolute health risks of vaping? My wife is an ex smoker (several years now) and I am an occasional cigar smoker (maybe a few a month). We both enjoy and miss the experience of smoking but have no need for the nicotine. Given that we currently don't smoke (effectively), what are the health risks of beginning vaping to get the enjoyment of it back but vape only zero nic mixes? I know nicotine is relatively safe (I've heard similar to caffeine) but if neither of us want or need it, why bother with it? So, any known serious risks of vaping to non-smokers?
