对四种流行的美国卷烟的主流和侧流烟雾进行了有毒和致癌物质的分析。这些香烟包括一支没有滤嘴的香烟，以及一支滤嘴香烟，每支香烟的烟雾产量分别为中等、低和超低。分析清楚地表明，与非滤嘴卷烟相比，本研究中所确定的12种有毒物质在滤嘴卷烟的主流烟雾中显著减少。在超低产卷烟的情况下，主流烟雾排放减少了约90%。与这一发现相反，滤嘴香烟侧流烟雾中相同的有毒和致癌成分的排放量并没有显著减少。侧流烟雾是环境烟草烟雾的主要贡献者，吸烟者和不吸烟者都暴露在环境烟草烟雾中。尽管吸烟者对主流烟雾成分的接触有所减少，这是因为按比例增加了低产量和超低产量香烟的消费量，以及较低的高烟雾产量香烟的消耗率，但来自烟草产品的室内污染物的致癌潜力并未减少。
The mainstream and sidestream smoke of four types of popular US cigarettes were analyzed for toxic and carcinogenic agents. The cigarettes included one without a filter tip, and one filter cigarette each with medium, low and ultralow smoke yields. The analyses clearly demonstrated that 12 toxic agents determined in this study were significantly reduced in the mainstream smoke of filter cigarettes, as compared with smoke yields from the nonfilter cigarette. In the case of the ultra-low yield cigarette, mainstream smoke emissions were reduced by about 90%. In contrast to this finding, the emissions of the same toxic and carcinogenic components into sidestream smoke of the filter cigarettes were not greatly reduced. Sidestream smoke is the major contributor to environmental tobacco smoke, to which both smokers and non-smokers are exposed. Although the exposure of the smoker to mainstream smoke components is decreased due to proportionally greater consumption of low and ultra-low yield cigarettes, and lower rates of consumption of cigarettes with high smoke yields, the carcinogenic potential of indoor pollutants originating from tobacco products is not diminished.
