In some objective analysis I wouldn't be surprised if drinking a bottle of Coke daily is worse than vaping once daily, even for teens.
Nicotine is highly addictive and bad for you health. You pretty much have a customer for life ... which is the point. So next to having something which is bad for you, inhaling glycerol, combined with a substance which is addictive and bad for your health, you also are at a financial loss for life.
And it's targeted at teens ...
(I think vaping should be legal, fwiw.)
