The sales of the lowest yield cigarettes (1-3 mg tar) seem to have been particularly resistant to the effects of promotion and advertising, while the sales of other low-yield cigarettes (4-9 mg tar) seem to have been increased by promotional efforts. This finding is consistent with the existence of a boundary of tar and nicotine acceptability below which consumers in general are not prepared to go. Use of lower tar cigarettes may be helpful for those who cannot stop smoking, but, since 1979, the percentage of cigarettes under 16 mg tar has changed little.
低焦油含量香烟（每支焦油含量1 - 3毫克）的销量似乎对促销和广告的影响特别有抵抗力，而其他低焦油含量香烟（每支焦油含量4 - 9毫克）的销量似乎因促销活动而有所增加。这一发现与焦油和尼古丁可接受度存在一个界限相符，低于这个界限，消费者一般不愿再降低焦油和尼古丁含量。对于那些无法戒烟的人来说，使用低焦油香烟可能会有所帮助，但是自1979年以来，每支焦油含量低于16毫克的香烟所占的百分比变化不大。
