It does not actually matter what you use – an e-cigarette with an atomizer or cartomizer, the engine that vaporizes the liquid is in the main the same; it includes a metal heating coil wrapped around a wick.
The first disadvantage of E-cigarette use is their cost. To start smoking tobacco cigarettes, requires a small cost per pack of cigarettes and a lighter. So the cost of traditional smoking “start” is very low.
The main and most important difference between e cigarettes and tobacco cigarettes is the lack of carcinogenic tar and other harmful products of combustion, which in tobacco cigarettes are more than 4 000. As a consequence – sparing influence on the smoker’s lungs and health in general, as well as reducing risk of a “passive” smoking.
