True they smoke for a while, but give up easier and carry on not even thinking about it.
Others battle a lifetime to quit, and when they do, they long for it for the rest of their life.
I don't think its purely an addiction thing. I think its deeper than that..that's why I used the word "genetics" (lack of a better term).
Big tobacco also knows that i'm sure...that's why they add addictive substances to tobacco.
I don't think it's genetics per se, unless you include addictive personality as a genetic trait, which I do believe is genetics based but is a life condition far beyond just smoking and vaping. So I'll accept the genetics argument on that basis, which makes sense.
Your point about the truly addictive "enhancers" cigarette manufacturers add that vaping doesn't is the big story. Totally right. Nicotine is not the biggest addiction factor I don't think and I know vaping is much, much easier to quit than combustible tobacco products. I've showed myself that every week when I need to go without vaping at a clients site for 8 or more hrs at a time without vaping. I couldn't have done that as a smoker. Seriously, I don't think I could have, and never really tried because the beast would come out at a certain point and I probably would have lost a client. Hard to remember myself that way with smoking, but my honest self knows that for the truth. That would be the angel on the right shoulder... hate that guy, he's so unreasonable sometimes. But the guy on the left shoulder talks nice and likes me. Very encouraging sort, in fact, he helped me place a big vape order this week. Right shoulder ...... now, he'll get over it.
So the nicotine argument that is the main weapon of anti-vapers is a lie. But powerful none the less. Lies become fact to the masses when told loud enough and often enough.
