1. There is has been a sharp drop in the number of smokers

2. There is has been an even sharper jump in the number of the vapers, especially concerning among youth.

3. The available evidence says that the inherent risks of vaping are an order of magnitude less than smoking.

As a society we're discussing whats the optimal public health policy to reduce vaping and smoking. Unfortunately these are substitutes so as we crack down on the availability of one we increase consumption of the other. And this is why it's important to understand the relative risks of vaping versus smoking. If they're similarly unsafe then it doesn't really matter how hard we crack down on vaping. But if smoking is far more dangerous than vaping(which the evidence points to) then we need to be much more careful about reducing vaping availability.
