I'm a smoker, too, but only in private. Only in my house or car (no kids in either place). Don't go out to bars and hang around on the street outside having a smoke, because my mom would come back to haunt me right there and then.
Ballygirl, I wouldn't be concerned the long-term effects of e-cigs. A little flavor, water, and glycerin. I think it's big tobacco scare-mongering, and also politicians drooling over tax revenues (esp in NY.)
I have a couple of e-cigs. One of them is better than the other, (I found the Blue to be useless). They were helpful in cutting back in half, with discipline. (Put that down and pick the other one up!) A lot of people have gone to 100% vaping. I wasn't able to. I actually like the flavor better than regular cigs (you can get whiskey-flavored "juice," mmmmmm).
Here's a forum devoted to it, if interested:
