I saw a piece on the NBC Nightly News tonight. They had a teenager being interviewed saying he used e-cigarettes. Showed him using a mod. His parents were aware of this (They interviewed the Dad, and expressed concern). Honestly, all this piece was missing was the screen crawler that said this message brought to you by Phillip Morris. I can't speak for other parts of the country, but in my area, it is common to see kids at the local high school smoke cigarettes. While I know that my observances aren't the be all/end all, I've yet to see any kid use an e-cigarette/mod.
