Research into second hand emissions from cigarettes and e-cigarettes (Abstract) has found that while there is a tenfold decrease in overall exposure to carcinogenic particulate matter from e-cigarettes compared to cigarettes, there were increased levels of certain toxic metals. The researchers noted that more of this came from the device itself as opposed to the liquid used in the device.
In recent years, electronic cigarettes have gained increasing popularity as alternatives to normal (tobacco-containing) cigarettes. In the present study, particles generated by e-cigarettes and normal cigarettes have been analyzed and the degree of exposure to different chemical agents and their emission rates were quantified. Despite the 10-fold decrease in the total exposure to particulate elements in e-cigarettes compared to normal cigarettes, specific metals (e.g. Ni and Ag) still displayed a higher emission rate from e-cigarettes. Further analysis indicated that the contribution of e-liquid to the emission of these metals is rather minimal, implying that they likely originate from other components of the e-cigarette device or other indoor sources. Organic species had lower emission rates during e-cigarette consumption compared to normal cigarettes. Of particular note was the non-detectable emission of polycyclic aromatic hydrocarbons (PAHs) from e-cigarettes, while substantial emission of these species was observed from normal cigarettes. Overall, with the exception of Ni, Zn, and Ag, the consumption of e-cigarettes resulted in a remarkable decrease in secondhand exposure to all metals and organic compounds. Implementing quality control protocols on the manufacture of e-cigarettes would further minimize the emission of metals from these devices and improve their safety and associated health effects.

yes you can get plain flavor like that and you get get a variety of "strengths" including 0 nicotine.you can go as high as 36mg/ml but it is recommended that those get diluted. it does taste like a regular cigarette and some go as far as to tweak the flavor so it tastes exactly like a particular brand. if you do get liquid with nicotine in it you do get the nicotine effect. you can also make your own liquid and add more flavors. the DIY community around this is pretty large and there is a ton of information
i recommend them all the time and many people have asked me about them because i always have mine. switching does take some control though. i see a lot of people that try them and go back because they buy the cheap e-cig or do not get the correct strength to replace their current habit. after the first week it is amazing at how bad smokers smell. from there you can gradually lower the "strength" of your nicotine and wean yourself off.
