In Pics: Smokers, here's an excuse to not kick butt

E-cigarette, an electronic substitute in the form of a rod, slightly longer than a normal cigarette, in Bordeaux, southwestern France.The changeable filter contains a liquid with nicotine and propylene glycol.When the user inhales as he would when smoking, air flow is detected by a sensor and a micro-processor activates an atomizer.
The atomizer injects tiny droplets of the liquid into the flowing air, producing a vapour.E-cigarette, which retails for 78 euros, is powered by a rechargeable battery.
