- How do e-cigarettes work
All e-cigarettes have a battery and a head unit. Rechargeable batteries are used, and the head (the end fittings at the mouthpiece end) consists of an atomizer coil which is heated by the battery,and a cartridge containing refill liquid. In some models the last two components are combined in a 'cartomizer'. When the switch is pressed, or in the case of auto models, when air is pulled through, the heating element vaporizes the liquid and produces a mist. You draw or pull air through it just like a tobacco cigarette. The water-based vapour contains flavouring, and nicotine if desired. No combustion is involved and nothing is lit - all that happens is a liquid is heated and vaporized. It's not smoking, but looks and feels like it.
- Why use an e-cigarette
The main reason is consumer choice, as an alternative to tobacco cigarettes.
The idea is to obtain the nicotine in a coolmist with a few well-known ingredients that are all approved for human consumption, instead of inhaling the smoke from burning plant materials. It is known that smoking tobacco cigarettes has many health issues and perhaps around a one-in-three chance of early death. There is little or no smell, no second-hand smoke, and no smell of smoke on your clothes and hair, and no risk of harming anyone else.
