I must admitted that although I consider myself a pretty up-to-date guy, every now and then I get surprised by something I have never hear of.
This occurred justa few minutes ago when I read about e-cigarretes on kevinmd.com.
"E-cigarettes are battery operated, and contain nicotine and other flavors that the user can inhale. Advertisements claim they are safer since they don’t burn tobacco."
I totally agree with Dr Kevin Pho and Dr Matthew Mintz. These devices are a bad idea.
