A Breakthrough? Electronic Cigarettes

I suppose someone had to do it. But, why? A Chinese company, Ruyan, has invented an electronic cigarette. It's a little cartridge with nicotine in it that you suck on like a cigarette. You don't inhale smoke, just air and nicotine. When you exhale, it's comes out as smoke that the company claims is harmless (yeah, right!). You can buy these if you live in China, Israel, Turkey, Australia and some European countries. The company says they will target the United States next.
