smoking allowed flights

I've never been on a flight where smoking was allowed.

Since I've been flying, smoking has always been banned on board. I really like this rule as cigarette smoke really bothers me. I have recently heard that there has been some consideration to allowing the new electronic cigarettes to be used in flight. I really hope this does not pass. I know people say that the smoke doesn't go "out" and is only ingested by the user. However, in my limited experience, I can say that I have personally smelled the  electronic cigarette when passing a user, and even seen "smoke" coming from it. I am not really sure how they work, but I do hope they don't allow them to be used in flight.

 That I'd like to see.
