In habitual smokers salivary cortisol responses to cigarette smoking were investigated. In the first study, 31 adults assigned to two experimental groups smoked either one or two cigarettes of their preferred brand. Mean salivary cortisol levels were significantly elevated after smoking of two cigarettes. In the second study, 10 smokers and 10 nonsmokers provided saliva samples at 20 min intervals over a 12-hr period. While environmental stimuli were paralleled in both groups overall cortisol output was significantly elevated in the smokers. These data suggest that 'normal' cigarette smoking can increase free cortisol levels.
对习惯性吸烟者唾液皮质醇对吸烟的反应进行了研究。在第一项研究中，31名成年人被分为两个实验组，分别吸一支或两支他们喜欢的品牌香烟。吸两支香烟后，唾液皮质醇平均水平显著升高。在第二项研究中，10名吸烟者和10名不吸烟者在12小时内每隔20分钟提供一次唾液样本。虽然两组的环境刺激相似，但吸烟者的总体皮质醇分泌量显著升高。这些数据表明，“正常”吸烟会增加游离皮质醇水平。
