So if the only thing in cigarettes that is addictive is nicotine why do people using the gum and patches and taking nicotine go back to smoking cigarettes instead of becoming addicted to the patches and gum?
Speaking from personal experience, the physical addiction.
The several times I tried to quit smoking, I always went back because of a stressful event. Whether it be a bad day at work, fight with the wife, or whatever, I needed to sit down, and physically inhale a cigarette. I needed the smoke coming from my mouth. I needed to feel that hit at the back of my throat.
With e-cigs, I get all of that. And I haven't smoked in over a month. Even on my worst days now, I do not need a cig. The e-cig provides everything that an analog used to provide for me.
As I said before, why do e-cigs work so well if we are addicted to sugar? Wouldn't pixie sticks be a better alternative?
PS. Did you happen to notice, the organization you linked to states clearly in several places that nicotine is the addictive substance in cigarettes? Even the people you are quoting don't agree with your statements.
