Not really right.. but again you also either didn't read the article, didn't get the point, or strongly object it? (And also ignore authentic experiences other people give here)? Beyond nicotine, which is addictive yes, there is more in the cigarette cocktail (especially in nowadays highly optimized industrialized ones) that is also addictive. So there is such a thing as a cigarette addiction.

Or in other words: Why do people only get little addicted and can easily stop chewing nicotin gums, while for only a small percentage of smokers it is possible to quit via the nicotin gum replacement?

Or in even other words: Both coffeine and heroine are addictive, but we can agree that there are differences?
