I think the issue is some previous data that we also discussed here, this data shows that if before we had N children smoking now we have N1 = 10*N children using the cool looking, sweet tasting, less harmful e-cigarettes. If we had N1 = N then I would consider it a good thing but unfortunately is not that, Btw I invented this numbers but the point still stands.
