Electronic cigarettes or e-cigarettes are battery operated nicotine delivery devices that are designed and used in a similar fashion as conventional cigarettes. These devices are presumed to deliver nicotine rapidly to its users without exposure to the many harmful chemicals present in conventional cigarettes.

Shisha pen

A shisha pen (electronic hookah, e-hookah or hookah pen) is an electronic vapourizer just like an e-cigarette. The products are indistinguishable from e-cigarettes, given that they are available with and without nicotine and the system of operation is almost the same.
