Although the popularity of small cigar brands that resemble cigarettes, including both little cigars (LC) and filtered cigars (FC), has been on the rise, little is known about the delivery of nicotine from these products. Our objective was to determine the nicotine yields of small cigars in comparison to cigarettes.
Nicotine yields from LC, FC, and 3R4F and 1R6F research cigarettes were determined from mainstream smoke generated on a smoking machine under the International Organization of Standardization (ISO) and Canadian Intense (CI) methods. Market characteristics (price and package label) and physical features (filter ventilation, product weight and filter weight, product length, and diameter) were also determined for eight brands of small cigars.
Nicotine yields in small cigars averaged 1.24 and 3.49 mg/unit on ISO and CI regimens, respectively, compared with 0.73 and 2.35 mg/unit, respectively, for the research cigarettes. Nicotine yields per puff were similar between small cigars and cigarettes. We also found that FC did not differ from LC in nicotine yields. FC and LC differ from each other in many physical design features (unit weight, filter weight, and filter length), but are similar in others (unit length, diameter, and filter ventilation).
Nicotine delivery from small cigars is similar to or greater than that from cigarettes. Thus, for future research and regulatory purposes, standard definitions need to be developed for small cigars, and FC and LC should be evaluated as separate entities.
Small cigars are similar to cigarettes in their design and use. Although nicotine yields per puff were similar between products, small cigars delivered substantially higher amounts of nicotine per unit than cigarettes. These findings support the growing body of evidence to justify regulating all small cigars, including LC and FC in a similar fashion as cigarettes.
尽管类似香烟的小雪茄品牌(包括小雪茄和过滤雪茄)的受欢迎程度一直在上升,但人们对这些产品中尼古丁的释放知之甚少。我们的目的是确定小雪茄与香烟相比的尼古丁释放量。
通过在吸烟机上使用国际标准化组织(ISO)和加拿大强烈(CI)方法生成主流烟雾,确定 LC、FC 和 3R4F 和 1R6F 研究香烟的尼古丁释放量。还确定了八种小雪茄品牌的市场特征(价格和包装标签)和物理特征(过滤通风、产品重量和过滤重量、产品长度和直径)。
在 ISO 和 CI 方案下,小雪茄的尼古丁平均释放量分别为 1.24 和 3.49mg/支,而研究香烟的尼古丁平均释放量分别为 0.73 和 2.35mg/支。小雪茄和香烟之间的每口尼古丁释放量相似。我们还发现 FC 和 LC 的尼古丁释放量没有差异。FC 和 LC 在许多物理设计特征(单位重量、过滤重量和过滤长度)上存在差异,但在其他方面(单位长度、直径和过滤通风)相似。
小雪茄的尼古丁释放量与香烟相似或更大。因此,为了未来的研究和监管目的,需要为小雪茄制定标准定义,并且应该将 FC 和 LC 作为单独的实体进行评估。
小雪茄在设计和使用上与香烟相似。尽管产品之间的每口尼古丁释放量相似,但小雪茄每支单位释放的尼古丁量却大大高于香烟。这些发现支持了越来越多的证据,证明有必要以类似的方式对所有小雪茄(包括 LC 和 FC)进行监管,就像对香烟进行监管一样。
