Good Morning Morgan.
Yes he is.
It's funny you should mention this. Thinking about it, I haven't even seen him smoking one of the e-cigs lately.
He just came back from a week in Illinois, and while there he picked up that nasty chest cold/cough thing going around (he's on antibiotics)
He just left the house, definately not smoking real cigs, I'd smell that 5 miles away, but he also wasn't smoking the e-cig either. I'll have to ask him if he's weaning off of that.
Like I've said before, I think a big part of it is you can continue to get all the "benefits" of why you smoke, i.e. holding a cigarette, seeing the "smoke" the taste, the nicotine....but without the 100,000 other chemicals.
