What is an eCig ?

An electronic cigarette, or e-cigarette, is an electrical device that attempts to simulate the act of tobacco smoking
by producing an inhaled mist bearing the physical sensation, appearance, and often the flavor and nicotine content
of inhaled tobacco smoke. The device uses heat, or in some cases ultrasonics, to vaporize a
propylene glycol- or glycerin-based liquid solution into an aerosol mist, similar to the way a nebulizer or
humidifier vaporizes solutions for inhalation. Most electronic cigarettes are designed to resemble actual tobacco
smoking implements, such as cigarettes, cigars, or pipes, but many take the form of ballpoint pens or
screwdrivers since those designs are more practical to house the mechanisms involved.
Most are also reusable, with replaceable and refillable parts, but some models are disposable.
The primary stated use of the electronic cigarette is as a smoking cessation device, as it attempts
to deliver the experience of smoking without, or with greatly reduced, adverse health effects
usually associated with tobacco smoke. Nevertheless, concerns have been raised that use of the
device still carries health risks, and that it could appeal to non-smokers, especially children,
due to its novelty, flavorings, and possibly overstated claims of safety.

The electronic cigarette was invented by Chinese pharmacist Hon Lik in 2003
and introduced to the market the following year.
