ABSTRACT
BACKGROUND: Recently, a variety of cigarettes which contain a low content of nicotine are on the market and the nicotine tends to be reduced continuously. However, studies have not yet fully demonstrated that low-nicotine cigarettes are subservient to quitting smoking. This study was designed to investigate the effects of the nicotine content on smoking attitudes and on the factors associated with successful smoking cessation. METHODS: One hundred twenty-five adult smokers, who had undergone a health examination in a general hospital, had their carbon monoxide measured after responding to the questionnaire. The items of questionnaire consisted of the duration of smoking, the age of starting to smoke, the number of attempts to stop smoking, recognition of nicotine dependence, and nicotine dependence score. RESULTS: The subjects consisted of two groups. One group was low nicotine group and the nicotine content was lower than 0.35 mg per cigarette. The other group was high nicotine group and the nicotine content was over 0.35 mg per cigarette. he age was younger and duration of smoking was shorter in low nicotine group. Monthly income, last schooling and number of attempts to stop smoking were higher in low nicotine group. There was no statistical significant differences between the two groups in the frequency of alcohol drinking, the age of starting to smoke, marital status, nicotine dependence, carbon monoxide concentration and recognition of nicotine dependence. CONCLUSION: As there was no differences in smoking habits which has infl uence on achieving quit smoking of low nicotine group, we made our conclusion that low nicotine cigarette might be unhelpful in quit smoking.
