We provided estimates of noncombustible tobacco product (electronic nicotine delivery systems [ENDS]; snus; chewing tobacco, dip, or snuff; and dissolvables) use among current and former smokers and examined harm perceptions of noncombustible tobacco products and reasons for their use.
We assessed awareness of, prevalence of, purchase of, harm perceptions of, and reasons for using noncombustible tobacco products among 1487 current and former smokers from 8 US designated market areas. We used adjusted logistic regression to identify correlates of noncombustible tobacco product use.
Of the sample, 96% were aware of at least 1 noncombustible tobacco product, but only 33% had used and 21% had purchased one. Noncombustible tobacco product use was associated with being male, non-Hispanic White, younger, and more nicotine dependent. Respondents used noncombustible tobacco products to cut down or quit cigarettes, but only snus was associated with a higher likelihood of making a quit attempt. Users of noncombustible tobacco products, particularly ENDS, were most likely to endorse the product as less harmful than cigarettes.
Smokers may use noncombustible tobacco products to cut down or quit smoking. However, noncombustible tobacco product use was not associated with a reduction in cigarettes per day or cessation.
我们提供了当前和曾经吸烟者使用不可燃烟草制品（电子尼古丁传送系统[ENDS]；鼻烟；咀嚼烟草、口含烟或鼻烟；以及溶解烟草制品）的数据估计，并检验了对不可燃烟草制品的危害认知以及使用这些产品的原因。
我们评估了 8 个美国指定市场区域的 1487 名当前和曾经吸烟者对不可燃烟草制品的认知、流行率、购买、危害认知和使用原因。我们使用调整后的逻辑回归来确定不可燃烟草制品使用的相关因素。
在样本中，96%的人至少知道一种不可燃烟草制品，但只有 33%的人使用过，21%的人购买过。不可燃烟草制品的使用与男性、非西班牙裔白人、年轻和尼古丁依赖程度更高有关。受访者使用不可燃烟草制品来减少或戒烟，但只有鼻烟与更高的戒烟尝试可能性相关。使用不可燃烟草制品的人，特别是 ENDS，最有可能认为这些产品比香烟的危害小。
吸烟者可能使用不可燃烟草制品来减少或戒烟。然而，不可燃烟草制品的使用与每天吸烟量的减少或戒烟无关。
