[QUOTE] [QUOTE] Given that nicotine is one of the most addictive drugs in existance[/QUOTE] Often quoted, but many studies supporting this idea use apparent dependence on tobacco products as a key measure of the degree of addiction, and are therefore somewhat skewed by the simple desire to smoke "because I enjoy it". STY's point, while over-general, does have an underlying basis - there are many factors, as you're fully aware, in stopping smoking, of which genuine, physiological dependence is clearly one, but it's not possible to isolate them, as there's never been, and never will be[1], a control-based study to separate psychological and social issues from the purely physiologiocal.[/QUOTE] I don't think social issues affect the addiction per se - I can remember lighting up in desperation when all the social pressures at the time were against it. I agree, however, that there are psychological as well as physiological factors at play, so if "addictive" is taken to apply to physiological dependancy only then maybe I should have used a different word - although an alternative doesn't immediately spring to mind. I still reject, however, STY's implicit assumption that failure to give up is not down simply to physiological dependancy. [QUOTE] In any event, I do believe that a significant proportion, possibly the majority, of failures-to-stop-smoking are at least partially caused by the desire to stop being based on social or other external pressures, and that the smoker, deep-down, doesn't want to stop in and for themselves.[/QUOTE] Agreed.
