TIS,

From what I have heard, the e-cigs are very popular with teens. So much so that it is becoming a major concern. Last fall, I was at a football game in Detroit inside of a dome and saw quite a few people with the e-cigs. I had never seen them before, but they seem to be gaining in popularity.

I always liked this exchange from "Austin Powers" -
Woman: "Austin, do you smoke after sex?"
AP: "I don't know, baby. I never checked."
