Said the director of the Center for Tobacco Control Research and Education at the University of California, San Francisco, quoted in "More Nonsmoking Teens Inhaling Flavored Nicotine Through Vaping," in the NYT.
Is nicotine alone really a problem? The article just says "Nicotine disrupts neurotransmitter activity and is highly addictive, particularly in a developing brain." If that's worse than caffeine — which the kids consume all the time — I'd expect the NYT to say so. Instead it goes on to mention the other ingredients — "solvents, formaldehyde" — in the e-cigarettes and this problem of e-cigarettes leading to real cigarettes.
I'm not buying into the great vaping scare.
