Guck, everyone has an e-cig now. It's not just teens. They're everywhere. Of course the numbers of underagers are going to rise when the entire population of ecig users rises. A year ago I didn't know what an ecig was. Now I rarely smoke a real cigarette.

Look at the numbers of brick e-cig shops from a year ago to today. I would guess that it's gone up 10 fold.

The only downside with this that I see is that it's much easier to hide an ecig than a real cig. I started smoking at 16 and my parents knew immediately. E-cigs can be smoked in the bedroom without parent's noticing.
