A method of assessing "buffering capacity" is described for comparison of the degree of acidity of alkalinity of the smoke of different tobaccos as presented to the oral and respiratory tracts of the smoker. Nicotine is more readily absorbed from an alkaline than from an acid smoke. The smoker of tobaccos giving a smoke of acid buffering capacity, in order to achieve full nicotine satisfaction, tends to smoke more and to inhale more, thus increasing lung cancer risks, than the smoker of tobaccos giving smoke of less acid or of alkaline buffering capacity.
本文描述了一种评估“缓冲能力”的方法，用于比较不同烟草烟雾呈现给吸烟者口腔和呼吸道时的酸碱度。尼古丁从碱性烟雾中比从酸性烟雾中更容易被吸收。与吸入酸性缓冲能力烟雾的烟草的吸烟者相比，吸入酸性缓冲能力烟雾的烟草的吸烟者为了获得充分的尼古丁满足感，往往会吸得更多、吸入更多，从而增加患肺癌的风险，而吸入酸性缓冲能力较小或碱性缓冲能力烟雾的烟草的吸烟者则不然。
