I'm not missing the point. There will be deaths, for sure, in the black market. That will have silver linings, whether you choose to look at it that way or not. The people that return to smoking will surely have knowledge of deaths from that. I'd be willing to wager (lots of money) that there will be fewer deaths from the vaping black market than there will be from the smoking legal market. So, if the not so serious vapers want to return to smoking, cause ya know, they'll be 'more safe' then again, I'll get out the world's smallest violin so that I can play a special tune for them for not daring to go to the black market.
The reality of the black market though will be that as many of you are stocking up and mixing your own stuff, (as you currently do), that some will mix it and distribute for (great) profit. So, kinda hard to have it both ways. That the black market (stuff) will be inherently deadly, but all the stuff that stockers will be using will be hunky dory, and relatively safe. If you think that (that black market stuff will be inherently dangerous), then you are clearly missing the point.
