I would still vape. I feel so much better than when I smoked, I'd never go back - but I do enjoy a good tobacco flavor and I do still like my nicotine. I've moving toward DIY juices (when I have the money to gear up) and I'm smart enough to learn to build a mod from scratch if I had to. And I would use the black market which will always exist. Don't forget that you can buy leaf tobacco tax-free - it's tobacco, not a tobacco product. It's tobacco products that are taxed to death.
The government claims to be watching out for our health and safety. It's a lie. They are looking for ways to get money, pure and simple. They don't give a damn about our health - in fact if we die off, that's a plus to them. So don't look for anything good to come from that direction. I don't know how the debate over vaping will eventually end - probably there'll be a SCOTUS case or three, and some stealth executive orders, but it is never about public safety. I want to learn to build mods out of copper pipe and batteries, do my own juices, and then....screw 'em.
