An electronic cigarette (e-cig or e-cigarette) is a cell-powered device which simulates smoking by producing a vapor that resembles smoke. It uses a heating element known as an atomizer that vaporizes a fluid solution. Some solutions contain a mixture of nicotine and flavourings, while others release a nicotine free flavour.
A standard such cigarette uses the following components: Atomizer, Customizers, and Clearomizers. Besides the electrolytic cell, the atomizer is the central element of every personal vaporizer. Though various types of atomizers are available in the market, they generally consist of a small heating element responsible for vaporizing liquid.
Almost all the devices that imitate the electronic cigarette form factor use a ‘customizer’ (a combination of cartridge and atomizer) or as an e-fluid delivery combination. The piece consists of fluid soaked foam that acts as an e-liquid holder. Clearomizers unlike cart tanks, use a clear tank in which an atomizer is inserted.
Liquid for producing vapor in electronic cigarettes, commonly known as e-juice or e-fluid. It is a solution of propylene glycol, vegetable glycerin, and/or polyethylene glycol 400 mixed with dense flavours; and optionally, a varying density of nicotine. The solution is mostly sold in pre-filled disposable cartridges.
Due to the relative newness of the technology and the possible relationship to tobacco laws and medical drug inhibition policies of various countries, electronic cigarette legislation and public health investigations are currently pending permission in many countries. Current laws differ widely, from one region to another with no regulations to others banning the devices completely.
The international tobacco manufacturing companies, identifying the build-up of a potential new market sector that could render traditional tobacco products useless ,are more and more getting involved in the manufacturing and marketing of their own brands of e-cigarette and in taking over existing e-cigarette companies and increasing their stocks.
