One of the things that really bothers me in this thread is the few posts I've seen saying those vapers that have quit smoking can just stop vaping too. I agree this is a solution, but it's not so easy really. The nature of addiction and dependency is just not that simple. Giving up nic, at least for me, is the easiest part of quitting if that's what I wanted to do. But that's only a small part of the addiction to smoking or vaping really. Of course smoking addiction is worse than vaping addiction I think with all the chemical additives that vaping doesn't have, and most of the ancillary dependencies of vaping probably originated from smoking dependencies... but vaping satisfies them quite nicely... and they still exist. Dependencies like hand to mouth ritual, sucking in a lungful of pseudo smoke, exhaling same, time of day I expect to get this ritual fix like after meals, etc. There are lots of carry overs from smoking that vaping satisfies that has nothing to do with nic fix, although that is part of it all. And even flavors play a very big part because in anticipation of the next toot on the mod is expectation of the flavor we know we will enjoy.
Before the huge price rise in cigarettes I would never have deviated from my favorite brand of smokes, and none of my friends would either. We had flavors we were used to and could anticipate (part of the dependency) and if a friend offered me one of his I would have to be fairly desperate to take it rather than run out to a CS to pick up a pack of my brand.
I know for me, after working for many hours without vaping, just the act of picking up my mod after I make to my car and out of my clients parking lot relaxes me before I even take a toot. And of course I relax even more after filling my lungs with that sweet, sweet flavor I had known was coming. And the onset of the nic effect after a short time validates the relaxing feeling I had when I picked up the mod and before I actually vaped. This is a small part of the addiction/dependency synergy. It's not a simple equation to understand or fix.
Finally, the argument that the vaper can just quit is narrow minded in the way that for the last 25 years at least this is the same argument non-smokers have used against smokers. It really makes me sad to see this argument used by vapers to other vapers.
