I do get it

However, one of the problems with ignoring ideologues is that you are allowing a repetition of a lie. I doubt that anybody would be vaping 45 mg/ml nicotine in the 90s. I wasn't a smoker then so I have no idea what was actually available, but, since there was no real market back then, I doubt that nicotine in high concentrations would have been generally available. If anybody who is not a flat earther knows, could you please tell me what the options were back then. As to my intelligence, I have a PhD in psychopharmacology and I have been studying drugs for almost 40 years, if I didn't appear to know something about this stuff I should be shot. On the other hand, you and several others here who have no specific training in the field seem to get it, and can even relay it so that others can understand it. That is real brilliance!
It is my understanding that vaping is only about 6-8 years old. There simply was no vaping in the 90s. Someone with a more first hand grasp of the history is welcome to correct me if I'm wrong on my era.
I agree that it is as hard to ignore an ideologue as it is to try to reason with them. Tough problem.
While I'm here, I found two interesting discussion points in your thread....
1) You claimed, I believe, that your anecdotal experience with your students is that those who smoked relatively briefly had no problems giving up smoking. IOW, the idea that nicotine (or cigarettes) "latches it's hooks in you quickly" is an urban legend of sorts. It's been so long for me I don't remember. But I respect that you spend your days surrounded by that particular lab rat. Here you claimed you quit smoking, without "withdrawal issues", after 6 years (at around age 17-18). That, by my way of thinking, is a "long" time. I wonder if you are somewhat of an outlier on that. Most people around here (and I'm including those with fresher recollections) say otherwise.
I'm not arguing the point, only mentioning that your experiences are not "mainstream" here, for whatever that is worth.
2) You got into the issue of psychological vs physical addiction. I should go back and re-read the thread to refresh my memory but I had a distinct sense that separating the physical from the "mental" is not a simple matter, nor is it very intuitive to a layman. My sense was that few of us probably understood what you were trying to say. Simply because we are not trained to understand that and it is not a simple matter.
You would have had a very difficult time convincing me, back around day 4-5 of my final (and successful so far) quit attempt, that what I was feeling was not physical. Those were my worst days, and they were rather ugly. Yet at the same time I understand that I am not in a position to argue the point

. It is quite complex indeed.
You said here that most of the dependency is behavioral, not chemical. Yet with vaping it is easy to separate that variable. By vaping 0mg juice. And if the user senses discomfort with 0mg juice than isn't there something chemical going on?
A similar issue with WTA. There are a number of people here that claim great benefit to WTA, in terms of easing their "withdrawal symptoms". And that is an issue of great interest here since WTA adds in some of the chemicals missing from tobacco that are thought to be addictive/dependent.
