The article starts with something that is, by most accounts, harm reduction among teenagers: “Teenagers are drinking less alcohol, smoking fewer cigarettes and trying fewer hard drugs, new federal survey data shows. But these public health gains have been offset by a sharp increase in vaping of marijuana and nicotine..." The statistics, unused in this article, are quite clear: alcohol, tobacco and hard drugs more harmful to personal and societal health than marijuana.

But then the NYT proceeds to whip up some nonsense about how harmful vaping marijuana is, staring, and really ending, as we have no clue how harmful this behavior is, with a quote: “'This is a very, very worrisome trend..."

This is fear mongering, pure and simple.
