Abstract: The deletorious health effects of smoking are generally known. In spite of that, great numbers of people still smoke tobacco in the whole world. It is primarily due to the addictive properties of nicotine. Cigarette smoking is also dependent on various social and psychologic factors making quitting very difficult. Among various treatment modalities for tobacco dependence we aimed to assess the efficacy of nicotine replacement therapy (NRT) vs group therapy. 325 subjects smoking at least 15 cigarettes/day for more than 3 years were studied. They were allocated to group therapy (neurolinguistic programming) or NRT (gum or patch) at their will. Non-smoking was validated at each of follow-up visits, at 1 and 2 weeks 1, 3, 6, 12 months by measuring CO in expired air. All groups were matched in age, smoking history and nicotine dependence. The best quit rate was observed as a result of group therapy (41% at 1 year, p. < 0.001) as compared to nicotine patch (2%) and nicotine gum (9%).
