JUUL is the fastest growing and highest selling brand of e-cigarette/vapor products in the USA. Assessing the effect of JUUL vapor products on adult smokers' use of conventional tobacco cigarettes can help inform the potential population health impact of these products.
Online surveys assessed past 30-day use of conventional cigarettes, JUUL vapor products, and other e-cigarettes/vapor products, monthly for 3 months, in a non-probabilistic sample of 15,456 US adults (21+ years). Participants were established current smokers of conventional cigarettes and recruited at their first purchase of a JUUL Starter Kit in a retail store or through JUUL's website. Logistic regression models examined factors associated with participants' odds of reporting past 30-day abstinence from cigarette smoking at the 3-months assessment.
Past 30-day smoking abstinence at the 3-months assessment was reported by 28.3% of the intent-to-treat (ITT) sample (n = 15,456) and 47.1% of an efficacy subset sample that completed the 3-months assessment (n = 9272). Covariate-adjusted odds for reporting past 30-day smoking abstinence at the 3-months assessment were significantly higher among participants who primarily used Mint or Mango flavored JUULpods (versus Virginia Tobacco flavor) in the past 30 days; exclusively used JUULpods in characterizing flavors (versus tobacco flavors) in the past 30 days; used a JUUL vaporizer on all 30 of the past 30 days; purchased their first JUUL vaporizer in a retail store (versus online); and first purchased a JUUL Starter Kit to help quit smoking completely. Odds for reporting past 30-day smoking abstinence were significantly lower among participants who, at study enrolment, had smoked regularly for ≥ 20 years, smoked ≥ 20 cigarettes per day, and smoked on all 30 of the previous 30 days.
At least 28.3% of adult smokers had quit smoking cigarettes completely after using a JUUL vaporizer for 3 months. More frequent use of a JUUL vaporizer and primary use of JUULpods containing characterizing flavors, particularly Mint and Mango, appears to be important to new JUUL users' chances of quitting smoking. The impact of banning retail sales of flavored JUULpods on adult smokers' likelihood of quitting should be closely assessed.
JUUL 是美国增长最快、销量最高的电子烟/蒸气产品品牌。评估 JUUL 蒸气产品对成年吸烟者使用传统香烟的影响，可以帮助了解这些产品对人群健康的潜在影响。
通过非概率抽样，在 15456 名美国成年人（21 岁及以上）中，每月进行 3 个月的在线调查，评估过去 30 天内使用传统香烟、JUUL 蒸气产品和其他电子烟/蒸气产品的情况。参与者为使用传统香烟的当前吸烟者，在零售商店或通过 JUUL 网站首次购买 JUUL 入门套件时被招募。使用逻辑回归模型，分析参与者在 3 个月评估时报告过去 30 天内戒烟的可能性与各项因素之间的关系。
意向治疗（ITT）样本（n=15456）中，有 28.3%的参与者在 3 个月评估时报告过去 30 天内戒烟，在完成 3 个月评估的有效亚组样本（n=9272）中，有 47.1%的参与者报告过去 30 天内戒烟。与过去 30 天内主要使用薄荷或芒果味 JUULpod（而非弗吉尼亚烟草味）相比，过去 30 天内仅使用 JUULpod（而非烟草味）描述口味、过去 30 天内每天使用 JUUL 蒸气器 30 次、在零售商店（而非网上）购买第一台 JUUL 蒸气器、首次购买 JUUL 入门套件是为了完全戒烟的参与者，报告过去 30 天内戒烟的可能性明显更高。与在研究入组时已连续吸烟 20 年以上、每天吸烟 20 支以上以及过去 30 天内每天吸烟 30 支以上的参与者相比，报告过去 30 天内戒烟的可能性明显更低。
至少有 28.3%的成年吸烟者在使用 JUUL 蒸气器 3 个月后完全戒掉了香烟。更频繁地使用 JUUL 蒸气器，主要使用含有描述性口味的 JUULpod，特别是薄荷和芒果口味，似乎对新 JUUL 用户戒烟的可能性非常重要。应该密切评估禁止销售调味 JUULpod 对成年吸烟者戒烟可能性的影响。
