The Electronic cigarette - a.k.a. the e-cigarette, personal vaporizer, e-cig, e-smoke, and P.V. - is a relatively new product invented by Hon Lik of Hong Kong less then ten years ago. The first electronic cigarette was called the Ruan, meaning "almost like smoke". It is an alternative to smoking traditional tobacco cigarettes. Instead of ingesting over 4,000 chemicals along with your nicotine when smoking tobacco cigarettes, the e-cigarette liquid nicotine - called e-liquid or e-juice - contains just four items: Water, propylene glycol and/or vegetable glycerin, nicotine, and flavour.

It is up to you to make an informed decision about electronic cigarettes, their risks, and their benefits.
