I think there has been an increase, Zoid.
But, that's like saying the rate of HIV sexually transmitted diseases has gone down, but the rate of HEP C infections has also gone UP. One is treatable, the other is curable.
The increase in never-smoking teen vapers ONLY is of concern if you don't also look at the fact that ALL teen smoking use has gone down.
If you take your one (out of context) statement-- never smoking teens are going up, OMG! It doesn't look that great.
If you make the next logical assumption and look at teen smoking rates going down, well you are gazing at the SAME population in a snapshot moment in time, and while one might state, "Yes, it's bad that never-smoking teens have vaped," it is equally as valid to state "Teen smoking has gone down, period."
If you don't want there to be a causal relationship between the two, fine. I think there IS one. I think teens who might otherwise have smoked are now vaping. I take zero issue with that. I am of the belief that a certain subset of teens are going to be terrible, tragic, un-law abiding creatures, I was one, I have met an infinitude in my life, and focusing on any of it (other than treatment, consequences, and even getting locked up for some stuff) is just a waste of time.
It's not the substance that is the issue, it's the behavior of the substance user, and harm reduction IN never smoking teens who take up vaping IS harm reduction PERIOD because otherwise they would be doing something else, like smoking.
Like Hep C, it's not super fantastic but oh boy does it beat a case of HIV.
