Polytobacco use and experimentation is common among young adults. Additional research is needed to determine how these patterns of use impact perceptions of tobacco-related harm and risk. The current study examined whether a relationship exists between an increased number of tobacco products used and decreases in perceptions of harmfulness and health risk.
Participants (N = 792) completed a survey assessing current/lifetime tobacco use, perceived absolute harmfulness of tobacco/nicotine products and perceived health risk of smoking. For some analyses, participants were grouped by polytobacco use status.
Among participants who ever tried a tobacco product, a greater number of products tried was associated with lower perceptions of harm (all p < .05). For e-cigarettes and hookah, nonusers rated tobacco products as more harmful compared to single product, dual, and poly users (all p < .05). Number of products tried predicted perceived harmfulness above and beyond demographic characteristics and polytobacco use status across all products. Similarly, number of products tried predicted perceived health risk above and beyond demographic characteristics and polytobacco use status for both lung cancer and heart disease risk.
Trying a greater number of tobacco products is associated with lower perceived harmfulness of tobacco products. Prospective studies are needed to determine if experimentation with more tobacco products leads to reductions in perceived risk of tobacco use and subsequent sustained use of tobacco.
多烟草制品使用和尝试在年轻人中很常见。需要进一步研究以确定这些使用模式如何影响对与烟草相关的危害和风险的认知。本研究旨在探讨使用的烟草制品数量增加与危害认知和健康风险感知下降之间是否存在关系。
参与者（N=792）完成了一项调查，评估了当前/终生的烟草使用、对烟草/尼古丁产品的绝对危害性的感知以及吸烟的健康风险感知。在某些分析中，参与者根据多烟草制品使用情况进行分组。
在曾经尝试过烟草制品的参与者中，尝试的制品数量越多，对危害的感知越低（均 P<.05）。与单一制品、双重制品和多制品使用者相比，非使用者对电子烟和水烟的评价认为烟草制品的危害性更大（均 P<.05）。尝试的制品数量预测了所有制品的危害感知，超过了人口统计学特征和多烟草制品使用状况。同样，尝试的制品数量预测了肺癌和心脏病风险的感知健康风险，超过了人口统计学特征和多烟草制品使用状况。
尝试更多种类的烟草制品与对烟草制品危害认知降低有关。需要进行前瞻性研究，以确定更多烟草制品的尝试是否会导致对烟草使用风险的感知降低，以及随后对烟草的持续使用。
