Nice article that shows both sides. The lady on the right eludes to a valid concern though. If some one is trying to quit smoking, puffing away on an eCig right next to them is not going to help any. For those with adictive tendancies, a smoker quiting smoking is no diffrent than a drug adict quiting ....... It's the Hardest thing they ever done. All we can do is say is "its not smoke, I'll turn the vapor feature down for you" taking a big gulp of air after each puff to lessen the perceived exhale.
When it's the sight of smoke, steam, or vapor that sets these people off, we really cant win this battle.
