While I pretty much agree with your entire post, I wouldn't mind exploring this a bit more...
I was not ever addicted to nicotine while smoking.
And I am not addicted to nicotine now while vaping in ANY conceivable way.
But I have some WTA juice on hand, and I do use it now and then.
It gives me a relaxing effect that I absolutely do not get from nicotine alone.
'
I use it so rarely that my WTA bottle is about to expire soon.
But then I really don't even vape that much anymore, so yeah, that's not surprising.
I believe I am one of the very few, if not only WTA users that doesn't feel they NEED it.
Just that sometimes, it really does hit a spot that nicotine does not hit.
