Replying to this with a few things to say.
First, your expressed feelings on not having another smoke again is one reason I think there will for sure be a black market with regards to vaping, if banning comes about. The idea that ex-smoking vapers would just gravitate towards smoking and continue with that habit I think is (possibly way) overhyped. I think many ex-smokers think that first smoke will be tasty and a wonderful experience. I strongly believe it would likely be so nasty they'd swear of smokes for good. And take whatever (teeny tiny) risks there are to get eLiquid on the underground market.
Second, I do think most ex-smokers are recovering addicts, but there would definitely be exceptions. Your post (aka your now hatred for smoking) tells me you have fully kicked the addiction. I'm sure you realize some may be skeptical of just how certain you are you'll never smoke again, but the only person's opinion that matters, about whether you are ever going to return to smoking, is yours.
Third, I profoundly disagree with those who think once an addict, always an addict. I obviously stated this earlier in the thread, but feel like elaborating. Again, vapdivrr is prime example of person that addict is not an applicable term. Recovering addict neither makes sense, truly. Recovery, I would say, allows for the possibility that one day in the future a cigarette may be smoked again. And perhaps more importantly, allows for the possibility that just one may be enjoyable enough that another after that is perhaps likely. Hence, a return to habitual use is seen as possible and then addiction sets in.
Yet, with recovery comes a sense of commitment. And I'd say the overwhelming majority (IMO) of vapers who were ex-smokers, or even are dual users, are committed to no longer being dependent on smoking. That's huge. We all know this. Non-smokers show up clueless to just how committed we are to longer being dependent on smoking.
Following up with that last point, my fourth and final item, is my speaking from dual use perspective. I'm a proud dual user. I've only said that about 50 times on the forums. Prior to making a commitment to no longer being dependent on smoking, I was, as a dual user, working through which product (vaping or smoking) did I truly enjoy more. I was surely vaping way more than smoking, but was mentally wavering between the idea that smoking for sure has things that I still enjoyed (then) daily, and that vaping just wasn't doing for me. Even, then I would call myself recovering addict. Because I think once a smoker commits even a little bit to vaping, they'll cut their smoking habit way back. Maybe not in the first month, but for sure by year 2, they are very likely nowhere near a PAD smoker. Which again, is huge.
There are a few reasons why I still choose to smoke, but the one I feel is pertinent to this topic is my ongoing desire to be a moderate smoker. Prior to vaping, I thought that not possible for smoking cigs. For the last 3 years or so, that is exactly how I'd describe myself. And currently moderation means, for me, one smoke every 3+ weeks, and up to as much as one smoke every 2.5 months. I would say that of the last 10 smokes I've had, which likely equals the amount I've had in 2019, maybe 3 of them were 'wonderful experience' type smokes. The rest were, meh, whatever. But still something I enjoy at the level of using moderately.
I think if vaping was banned, even from the black market, and somehow (magically) I couldn't ever vape again, I would plausibly return to habitual use of smoking. Then again, as someone who's gone cold turkey from smoking, three times (never less than a year), I do strongly believe I could stop.
But like most on this thread, and on this forum, I do so enjoy my nicotine intake. More please.
