E-cigarettes are small devices that look like regular cigarettes. Their operation involves the vaporization of the liquid nicotine. Thus they are free of tarry substances and health friendly. E-cigarettes can be used literally everywhere, including the public places. The smoke that is exhaled by e-smokers is an odourless water vapour.
Moreover, e-cigarettes taste like real cigarettes. However, as opposed to regular cigarettes, e-cigarettes offer a wide range of aromas. E-cigarette refills differ in flavour. It may correspond to flavour typical of popular traditional cigarette brands or comprise a unique taste.
