The shisha pen will not be popular among die-hard smokers, because unlike all different types of e-cigarettes, you cannot smoke tobacco with the shisha pen. This cigarette-like stick is available in different colors and is available in various tobacco-free flavors. After 500 to 600 puffs it is empty and can be thrown away. The disposable e-cigarette is also primarily intended for occasional smokers. Of all types of e-cigarettes, the disposable e-cigarette is the most like a real cigarette and it contains tobacco. After 300 to 800 puffs you will have to buy a new disposable e-cigarette.
