What Is An Electronic Cigarette???

I'm not a smoker, so maybe that's why I'm missing the charms of this product. Apparently it's a metal shell of a cigarette that makes water vapor instead of smoke, and looks like a cigarette. I saw this advertising on a computer game site, of all places!

From their website: "Smoking Everywhere E-Cigarette has no tobacco, no tar, no real smoke and no other chemicals like traditional cigarette that can cause lung cancer. However, It looks like a real cigarette, feels like a real cigarette and tastes like a real cigarette, yet it isn’t a real cigarette... It is also cheaper and healthier than real cigarettes!!!"

Wow, *electronic* smoking looks really glamorous!
