They are safer than cigarettes FACT
lol@deadly...the liquid is deadly if swallowed I agree though
"One of the only studies conducted to date on the safety of e-cigarettes has been by Murray Laugesen, a researcher on smoking policy and cigarettes and former principal medical officer of New Zealand’s Ministry of Health and Public Health Commission. Laugesen’s health consulting company contracted with seven laboratories to conduct independent tests on the nicotine cartridges of the Ruyan brand of e-cigarettes, which Laugesen then analyzed. The study—sponsored by Ruyan, the company that invented e-cigarettes—has a disclaimer stating that the findings are those of the author, who holds no stock in Ruyan and derives no financial benefit from the company.

The study analyzed the composition of the “smoke” emitted from the e-cigarettes and the cartridge liquid, as well as the presence of volatile compounds in the headspace above the cartridge liquid, among other measurements. The data showed that each puff contained one-third to one-half the nicotine found in a puff of a tobacco-containing cigarette, and the inhalation toxicity of propylene glycol is “not an issue.” It also found that carcinogenic heavy metals such as chromium, arsenic, and nickel, which have been found in cigarette tobacco, are not present in the cartridge liquid."
