Let Natural Selection take it's course. All regulation does is bring the responsible down to the lowest common denominator of the irresponsible. If someone really 'cares' (actually 'cares'... not just say they care so they sound morally superior to their peers) that someone who vapes 72mg nic, dies, then they are just as big an idiot. The ones that say they care to sound morally superior are bigger idiots.
If I had my way, I most certainly would let the gene pool thin itself out as evolution sees fit. But the establishment now thinks that we need it to do what it considers to be the best thing for us. Some do want that, and in fact would be lost if they didn't do that, but (the sad thing) most responsible people, the majority, don't want the state to run our lives.
I wouldn't care one iota if the state butted it's nose out of our business with immediate effect. But I don't get to make that call unfortunately
