Here is a great relief in order to smokers who are tired of being blamed with regard to smoking and leading to
trouble to the person standing nearby- electronic cigarettes. This is completely smokeless
and hence it is harmless compared to traditional cigarettes. An electronic cigarette is a
nicotine delivery device that is operated with the support of a battery. In the market it
is also known as e-cigarette or vaporize cigarette.

There are two types of electronic cigarettes- smoke style and pencil style. Cigarette design
resembles an actual cigarette while pen design resembles a ball point pen which is available
in a variety of colors. An electronic cigarette includes four basic parts- a mouthpiece,
heating element, battery, and electronic circuits.

Mouthpiece or cartridge is fixed at one end of the cigarette. It's made of plastic that
acts as a cup to accommodate the liquid to become vaporized. The inner side from the mouthpiece has a
step which allows free flow of air from the outer tip from the tube. This is required
to inhale watery vapor into the mouth. The liquid contains nicotine. It is available in the market
along with varying doses associated with nicotine. There are also fluids that do not have smoking; instead it
contains a variety of interesting flavors. One can choose based on the need. Once the
fluid is depleted, the capsule can be removed and substituted for a new one or it can be
refilled with fluids available as e-liquid or e-juice.

The heating element also known as atomizer is used to heat the liquid. Consequently, it
atomizes or vaporizes the liquid to be puffed in. The heating element is also replaceable.
The battery used should be rechargeable, lithium electric batteries.

The mechanism of smoking using an electric cigarette is as the person inhales, air
flows in from the outer suggestion of the tube. This particular either activates the heating element via a good
airflow sensor or even by pressing a button in the tube since the person inhales. Therefore
vaporizes the liquid to make a vapor-like smoke which doesn't have the persisting
smell of the tobacco.
