As time goes by, more and more studies are being done by more than a few pillars of the scientific community on the health effects of E-cigarettes. I would say dangers of E-cigarettes, but the results of these tests have unanimously determined that there are no dangers to speak of when one is in fact speaking of electronic cigarettes and the vapor they produce. The studies that have been completed thus far consist of the following data groups: short and long term exposure to E-cigarette vapor, toxicity levels of inhaled vaporized nicotine/propylene glycol/vegetable glycerine, levels of secondhand exposure to E-cig vapor, and presences of dangerous/carcinogenic chemicals in E-cig vapor. As stated above, the results of these controlled, scientific analyses and tests (even those done by objective, third-party organizations) are all highly in favor of electronic cigarettes being highly effective at delivering a safe, harmless, and danger-free tobacco-replacement experience.
One study done by the Roswell Park Cancer Institute (Study documents secondhand exposure to nicotine from electronic cigarettes -- ScienceDaily) concluded that although E-cigarettes do emit a substantial amount of nicotine, depending of course on the nicotine content of the e-liquid being used in the E-cig liquid, they did not emit any carbon monoxide or any other toxic organic or inorganic compounds. They also went on to explain that the nicotine emissions were nowhere near as high as those produced by analog/tobacco cigarettes. This cancer institute freely admit in the results that the secondhand exposure to nicotine from E-cigarette vapor is ten times less than from tobacco smoke...
