Best-selling "light" cigarettes (9-12 mg tar, by FTC method; Federal Trade Commission, 1990) generally employ filter vents to reduce standard tar and nicotine yields. Earlier research on "ultra light" cigarettes (1-4 mg tar) showed that filter vents were blocked by human smokers leading to dramatic increases in tar and nicotine yields. An objective indicator of vent blocking was applied to a sample of 158 discarded light cigarette butts, and results indicated extreme vent blocking in 47% 27% ( +/- 8, 95% CI), some vent blocking in 26% ( +/- 8), and no vent blocking in 47% ( +/- 8). Cigarette consumers need to be informed of the risks of vent blocking as a countermeasure to the marketing of light cigarettes to health-conscious smokers.
畅销的“淡味”香烟（按照联邦贸易委员会1990年的方法测定，焦油含量为9 - 12毫克）通常采用滤嘴通风口来降低标准焦油和尼古丁含量。早期针对“超淡味”香烟（焦油含量为1 - 4毫克）的研究表明，人类吸烟者会堵塞滤嘴通风口，导致焦油和尼古丁含量大幅增加。将通风口堵塞的一个客观指标应用于158个丢弃的淡味香烟烟蒂样本，结果显示47%（±8，95%置信区间）的烟蒂通风口堵塞严重，26%（±8）的烟蒂有一定程度的通风口堵塞，47%（±8）的烟蒂没有通风口堵塞。需要告知香烟消费者通风口堵塞的风险，以此作为针对向注重健康的吸烟者推销淡味香烟的一种应对措施。
