In 76 smokers, correlations between plasma nicotine and alveolar carbon monoxide levels of the individual smoker and the nicotine and CO yields of his cigarette were very poor. In 24 smokers of low-nicotine, low-tar cigarettes, mean alveolar CO levels did not differ from those of smokers of regular cigarettes. Mean plasma nicotine levels were lower in smokers of low-nicotine cigarettes, but a wide overlap of individual values occurred. The implication that an individual shifting to ultra-low-tar cigarettes reduces risks of cardiopulmonary disease is unwarranted.
在76名吸烟者中，个体吸烟者的血浆尼古丁与肺泡一氧化碳水平之间以及其香烟的尼古丁与一氧化碳释放量之间的相关性非常低。在24名吸低尼古丁、低焦油香烟的吸烟者中，平均肺泡一氧化碳水平与吸普通香烟的吸烟者并无差异。吸低尼古丁香烟者的平均血浆尼古丁水平较低，但个体值有很大重叠。认为个体转向超低焦油香烟可降低心肺疾病风险这一观点是没有根据的。
