进行了一项研究，以确定是否吸烟（1）定期，（2）低尼古丁低焦油，或（3）非烟草（生菜叶）香烟对个人的碳氧血红蛋白（COHb）水平有不同的影响。研究人群中的每个受试者都参加了两次五种“吸烟治疗”，其中他们吸烟各种烟草和非烟草香烟。呼出的空气一氧化碳（CO）的样本，每天四次，以估计COHb浓度。结果表明，不同的香烟制剂不会导致受试者的COHb水平的显著变化。然而，个体吸烟者之间的COHb存在显著差异。可能是吸入实践或因素（如肺功能）的差异在确定个体在吸烟时是否达到低、中或高COHb水平方面具有一定的重要性。
A study was carried out to determine whether smoking (1) regular, (2) low-nicotine-low-tar, or (3) nontobacco (lettuce leaf) cigarettes has a differential effect upon an individual’s carboxyhemoglobin (COHb) level. Each subject in the study population participated twice in five “smoking treatments” in which they smoked various tobacco and nontobacco cigarettes. Expired-air carbon monoxide (CO) samples were taken four times daily to estimate COHb concentrations. Results indicate that different cigarette preparations do not result in significant variation in a subject’s COHb level. There was a significant difference, however, in COHb between individual smokers. It may be that differences in inhalation practices or factors such as pulmonary function are of some importance in determining whether an individual achieves low, moderate, or high COHb levels while smoking.
