Laboratory-based evidence is inconsistent regarding the regulation of nicotine intake for habitual smokers. The present case report describes an in vivo double-blind alteration of nicotine level for two long-term, heavy smokers. In spite of large changes in nicotine intake, the frequency of smoking remained stable. It was concluded that other variables may play an equal or more important role than nicotine in governing smoking behavior in the natural setting.
关于习惯性吸烟者尼古丁摄入量的调节,基于实验室的证据并不一致。本病例报告描述了两名长期重度吸烟者体内尼古丁水平的双盲改变。尽管尼古丁摄入量有很大变化,但吸烟频率保持稳定。得出的结论是,在自然环境中,其他变量在控制吸烟行为方面可能比尼古丁发挥同等或更重要的作用。
