Cigarettes with flavors such as mocha and citrus have been introduced in growing numbers. Besides their potential marketing appeal to nonsmokers, there is concern that flavors might mask smoke harshness, making inhalation easier. This pilot study evaluates differences in puff topography and cigarette ratings among 20 college student smokers smoking Camel Light (10mg Tar, 0.9 mg nicotine, 35% filter ventilation) and Camel Exotic Blend cigarettes (11 mg Tar, 0.9 mg nicotine, 23% filter ventilation). Carbon monoxide boost was measured by assessing alveolar carbon monoxide (CO) levels before and after smoking each cigarette. Participants also rated each cigarette on characteristics such as strength, irritation, and taste. We found that participants took smaller puffs on the Exotic Blend versus Camel Light (42 mL vs. 48 mL, p<0.001), but there was no reliable difference in total smoke volume (613.9 mL vs. 630.7 mL, p=0.79) or CO boost (6.2 ppm vs. 6.2 ppm, p=0.90). Exotic Blend cigarettes were rated as more different from the participant's usual brand, but otherwise the taste ratings did not differ. Overall, these preliminary data suggest that adding flavors to cigarettes may not significantly impact how they are smoked by current smokers.
带有摩卡和柑橘等口味的香烟数量越来越多。除了它们对不吸烟者可能具有的市场吸引力外，人们还担心这些口味可能掩盖烟雾的刺激性，使吸入更容易。这项初步研究评估了20名大学生吸烟者吸食骆驼淡味香烟（焦油10毫克、尼古丁0.9毫克、滤嘴通风率35%）和骆驼异国风味混合型香烟（焦油11毫克、尼古丁0.9毫克、滤嘴通风率23%）时的抽吸形态和香烟评级差异。通过评估每支香烟吸食前后的肺泡一氧化碳（CO）水平来测量一氧化碳增加量。参与者还根据强度、刺激性和味道等特征对每支香烟进行评级。我们发现，与骆驼淡味香烟相比，参与者吸食异国风味混合型香烟时的抽吸量较小（42毫升对48毫升，p<0.001），但总烟雾量（613.9毫升对630.7毫升，p=0.79）或一氧化碳增加量（6.2 ppm对6.2 ppm，p=0.90）没有可靠差异。异国风味混合型香烟被评为与参与者常用品牌差异更大，但在其他方面，味道评级没有差异。总体而言，这些初步数据表明，给香烟添加口味可能不会显著影响当前吸烟者的吸烟方式。
