Representative samples of smokers of regular middle tar and regular low tar cigarettes responded to a questionnaire concerning their smoking habits and participated in a blind product test, returning 24 hour butt collections from the smoking of both middle tar and low tar cigarettes. An estimate of the mouth intake of tar derived from a measurement of filter nicotine confirmed partial compensation by the low tar smokers relative to the middle tar smokers, resulting in 32% lower tar delivery rather than the 46% expected from the standard machine values. Most middle tar smokers (98%) achieved an estimated tar delivery within or below that of the league table middle tar band when smoking middle tar cigarettes, while 70% of low tar smokers had a mouth intake of 10 X 49 mg or below within the low tar band when smoking low tar cigarettes. These results support the current tar league tables as a guide to the smoker in selecting a lower delivery cigarette.
抽取了吸普通中焦油香烟和普通低焦油香烟的吸烟者作为代表性样本，他们填写了一份关于吸烟习惯的问卷，并参与了一项盲品测试，提供了吸中焦油和低焦油香烟后24小时的烟蒂收集样本。通过对滤嘴尼古丁的测量得出的焦油口腔摄入量估计值证实，低焦油吸烟者相对于中焦油吸烟者存在部分补偿现象，导致焦油输送量降低了32%，而非标准机器值所预期的46%。大多数吸中焦油香烟的吸烟者（98%）在吸中焦油香烟时，估计的焦油输送量处于或低于排行榜中焦油等级范围，而70%的低焦油吸烟者在吸低焦油香烟时，口腔摄入量在低焦油等级范围内为10×49毫克或更低。这些结果支持了当前的焦油排行榜，可作为吸烟者选择低输送量香烟的指南。
