During 2011-2015, increased electronic cigarette (e-cigarette) and hookah use offset declines in cigarette and other tobacco product use among youths (persons aged <18 years) (1). Limited information exists about which tobacco product introduced youths to tobacco product use. Patterns of first use of e-cigarettes among Oregon youths who were tobacco users were assessed in the Oregon Healthy Teens 2015 survey, a cross-sectional survey of eighth and 11th grade students in Oregon. Respondents were asked, "The very first time you used any tobacco or vaping product, which type of product did you use?" Among students who had ever used any tobacco product (ever users), e-cigarettes were the most common introductory tobacco product reported by both eighth (43.5%) and 11th (34.4%) grade students. Among students who used a tobacco product for ≥1 day during the past 30 days (current users), e-cigarettes were the most common introductory tobacco product reported by eighth grade students (44.4%) and the second most common introductory tobacco product reported by 11th grade students (31.0%). Introductory use of e-cigarettes was commonly reported among youths in Oregon who were ever or current tobacco users, underscoring the importance of proven interventions to prevent all forms of tobacco use among youths (2,3).
在2011 - 2015年期间，电子烟和水烟使用的增加抵消了青少年（年龄<18岁者）中卷烟及其他烟草制品使用的下降（1）。关于是哪种烟草制品使青少年开始使用烟草制品的信息有限。在俄勒冈州健康青少年2015年调查（一项针对俄勒冈州八年级和十一年级学生的横断面调查）中，评估了俄勒冈州烟草使用者中的青少年首次使用电子烟的模式。受访者被问及：“你第一次使用任何烟草或电子烟产品时，使用的是哪种产品？”在曾经使用过任何烟草制品的学生（曾经使用者）中，八年级（43.5%）和十一年级（34.4%）学生报告的最常见的引入性烟草制品均为电子烟。在过去30天内使用烟草制品≥1天的学生（当前使用者）中，八年级学生报告的最常见的引入性烟草制品为电子烟（44.4%），十一年级学生报告的第二常见的引入性烟草制品为电子烟（31.0%）。在俄勒冈州曾经或当前使用烟草的青少年中，普遍报告有首次使用电子烟的情况，这凸显了采用经过验证的干预措施来预防青少年中所有形式烟草使用的重要性（2,3）。
