An electronic cigarette also called an e-cig or e-cigarette is a replacement for the old fashioned burning nicotine cigarettes.

These personal vaporizer (PV) or electronic nicotine delivery system (ENDS) are battery powered vaporizer units shaped which replace cigarette’s and have been designed to feel similar to real tobacco smoking.

The operation is simple with the user inhaling an aerosol called vapor rather than cigarette smoke.

E-cigarettes typically have a heating element that atomizes a liquid solution which is known as e-liquid which contain a mixture of propylene glycol, glycerin, nicotine, and flavorings.

E-liquids are also available without propylene glycol, without nicotine, or without flavors.
