You would probably take in more nicotine from eating a meal of eggplant than you would get from secondhand vapor. You wouldn't get enough from secondhand vapor to have psychoactive effects, let alone come anywhere near toxicity. Here is some reference to an indoor air quality showing vaping to not harm other people: www.ivaqs.com Here is reference to a study showing that nicotine did not promote lung cancer growth: http://www.aacr.org/home/public--media/aacr-in-the-news.aspx?d=2318 http://www.aacr.org/home/public--media/aacr-in-the-news.aspx... All sorts of things we take in can "promote cancer growth". Nicotine by itself is so far from a carcinogen that IARC doesn't even investigate it as one. There are roughly 50 components of tobacco and tobacco smoke called the "Hoffman analytes" which are the carcinogens. There are studies showing the relative cardiovascular and cancer risk, and the worst carcinogens are produced by burning plant material. These are not present in ecigs. Some studies which are dubious because of the choice of equipment and researchers not simulating the way ecigs are actually used have shown a handful of components way down the list of dangerous ingredients. Other studies have been done where these didn't even show up, but we are talking about things like formaldehyde and acetaldehyde near the level put out by smoking. If you compare the cancer risk of these to smoking, you are still looking at less than 5% of the cancer risk of smoking (probably under 1% really).
