BACKGROUND
As of March 2019, JUUL electronic cigarettes are the most popular e-cigarette on the U.S. market, but little is known of nicotine exposure and dependence on JUUL and user experience.
METHODS
JUUL users participated in a community-based study involving questionnaires, saliva collection and a qualitative interview.
RESULTS
Fifteen participants were enrolled (80% male, 53% White) and had an average age of 29.8 (standard deviation = 10) years. Daily exposure to nicotine assessed via salivary cotinine was similar to those reported for other e-cigarette and tobacco cigarette users in general. The majority reported low to moderate nicotine dependence. Qualitative interview themes included: the importance of social networks in adoption and use of the product; device features such as small size and vapor cloud reinforced product use; the product provided satisfaction compared to a tobacco cigarette; and a perceived sense of addiction to the product.
CONCLUSIONS
JUUL e-cigarettes expose users to levels of nicotine similar to other e-cigarettes but may be more satisfying due to unique device features. JUUL may be quite acceptable to tobacco cigarette smokers who are seeking to quit. However, it holds addictive potential and can reinforce long-term nicotine use.
背景
截至 2019 年 3 月，JUUL 电子烟是美国市场上最受欢迎的电子烟，但人们对 JUUL 电子烟的尼古丁暴露和依赖程度以及用户体验知之甚少。
方法
JUUL 用户参与了一项基于社区的研究，该研究包括问卷调查、唾液采集和定性访谈。
结果
共招募了 15 名参与者（80%为男性，53%为白人），平均年龄为 29.8（标准差=10）岁。通过唾液可替宁评估的每日尼古丁暴露水平与一般电子烟和传统香烟使用者的报告相似。大多数人报告尼古丁依赖程度较低至中度。定性访谈的主题包括：社交网络在产品采用和使用中的重要性；设备的特点，如体积小、烟雾大，增强了产品的使用；与传统香烟相比，该产品能带来更多满足感；以及对产品的成瘾感。
结论
JUUL 电子烟使使用者暴露于与其他电子烟相似水平的尼古丁下，但由于其独特的设备特点，可能会更令人满意。对于那些试图戒烟的传统香烟吸烟者来说，JUUL 可能很容易接受。然而，它具有潜在的成瘾性，并可能强化长期使用尼古丁。
