BACKGROUND
Tobacco vaporizers heat tobacco without burning it, to produce an inhalable aerosol. Various models have recently appeared on the market, mostly manufactured by the tobacco industry, but few of the studies published on tobacco vaporizers are independent from the manufacturers. The goals of this study were to explore who uses tobacco vaporizers, how these products are used, reasons for utilization, perceived advantages and risks.
METHODS
Online questionnaire collected from October 2016 to January 2018 in self-selected visitors aged > 18 to an anti-addiction website.
RESULTS
We obtained 170 valid responses, of whom 104 were using tobacco vaporizers. For homogeneity, we included only the 102 users of the Brand 1 tobacco vaporizer in our analysis, as there were only two users of other vaporizers. Among these 102 vaporizer users, about half were current cigarette smokers (57%), the rest were former cigarette smokers. The median age was 41, and the median duration of utilization was 9 months. Most (88%) used the vaporizer daily, 8% were occasional users and 4% were past users. Among current smokers, 80% were currently trying to reduce their cigarette consumption and 29% were trying to quit. The vaporizer was used mainly to replace cigarettes (94%), because it was perceived to be less toxic than cigarettes (89%), to help stop smoking or to avoid starting smoking again (72%), or to reduce cigarette consumption (71%). Current smokers who were daily or occasional vaporizer users reported smoking a median of 8.0 cigarettes per day, compared with 20.0 per day before they started to use the vaporizer (p < .0001, Wilcoxon signed-rank test).
CONCLUSIONS
In this online sample of early adopters, Brand 1 was by far the most frequently used tobacco vaporizer. It was used by current or former smokers only, mainly to replace cigarettes, and satisfaction ratings were good. Users considered the tobacco vaporizer to be less toxic than cigarette smoke and perceived it to be helpful for reducing or stopping smoking.
背景
烟草蒸发器通过不燃烧烟草来加热烟草，从而产生可吸入的气溶胶。最近市场上出现了各种型号的蒸发器，大多由烟草行业制造，但关于烟草蒸发器的少数已发表的研究都与制造商有关。本研究的目的是探讨谁在使用烟草蒸发器，这些产品是如何使用的，使用的原因，感知的优势和风险。
方法
我们于 2016 年 10 月至 2018 年 1 月期间在一个反成瘾网站上自行选择的访客中收集了在线问卷。
结果
我们共获得 170 份有效回复，其中 104 人正在使用烟草蒸发器。为了保持一致性，我们仅将 Brand 1 烟草蒸发器的 102 名使用者纳入分析，因为只有 2 名使用者使用其他蒸发器。在这 102 名蒸发器使用者中，约一半是当前吸烟者（57%），其余是曾经的吸烟者。中位年龄为 41 岁，使用蒸发器的中位时间为 9 个月。大多数（88%）人每天使用蒸发器，8%的人偶尔使用，4%的人过去使用过。在当前吸烟者中，80%的人目前正试图减少吸烟量，29%的人试图戒烟。蒸发器主要用于替代香烟（94%），因为人们认为它的毒性比香烟（89%）小，有助于戒烟或避免再次吸烟（72%），或减少香烟消费（71%）。每天或偶尔使用蒸发器的当前吸烟者报告每天平均吸烟 8.0 支，而在开始使用蒸发器之前每天吸烟 20.0 支（p<0.0001，Wilcoxon 符号秩检验）。
结论
在这个早期采用者的在线样本中，Brand 1 是迄今为止使用最广泛的烟草蒸发器。它仅被当前或曾经的吸烟者使用，主要用于替代香烟，且满意度评分较高。用户认为烟草蒸发器的毒性比香烟烟雾小，认为它有助于减少或停止吸烟。
