My friend has one. A couple near where we live imports them from the USA and sells them.

You're talking about 'happy vapper' (sic) right? A battery operated hookah cigarette? They are pretty neat.

It's not too silly because it can help with quitting smoking, which while I argue to be a harmless activity should not really be something encouraged ;D

However I don't think I would ever get one because I would be even more pretentious than I am.
