For the reason you mention, I think we need to be very cautious about who is using e-cigarettes. As I've said before, the only group that should see marketing of e-cigarettes are current tobacco smokers. Other than that, there's no benefit to anyone trying e-cigarettes. We need to make sure that they stay out of the hands of young people and that non-smokers aren't persuaded to try them.
