Is it true that the nicotine VAPOR in e-cigs DOES NOT STAIN porcelain or regular teeth? If so, why not? This staining is one of the reasons (among others) that I want to stop smoking cigarettes.  I have over $12,000 in beautiful porcelain caps up front! 

Quitting on smoking is always difficult. But with the right motivation and knowledge, you'll be able to pass it through. And the first day without cigarette is really the hardest day. I know that, because I was once a chain smoker, but now, e-cigarette made a difference in my life, and I was able to save money too.

Is it really the nicotin damagin you theeth? I think there are other chemiicals the reason for this problem.

This would explain this difference between electronic cigarettes and traditional cigarettes.
