The rapidly evolving landscape of vaping devices has complicated analyses of use patterns among youth and young adults. The current study describes the prevalence of use, substances vaped, and purchasing behaviors across five different vaping device categories.
Participants (n = 2505; mean age = 19.2, SD = 0.46) from a cohort in the Los Angeles area completed web-based surveys from June 2018 to October 2019. For each of four device type categories depicted via digital images (any pod-style vape, cigalike, box-mod, vape pen) and for JUUL specifically, participants reported ever and past 30-day use, substance vaped (mostly nicotine, nicotine and tetrahydrocannabinol [THC], mostly THC, neither), ownership of device (yes/no), where they obtained that device (eg, purchased themselves, from a friend), and if purchased, purchase location (eg, vape shop, online).
Overall, 44.9% reported ever use, and 26.2% reported past 30-day use of at least one of the devices. The prevalence of past 30-day use was highest for pod-style vapes (any pod = 17.0%; JUUL = 15.1%). Among respondents who reported ever owning any device (n = 643 [25.7%]), 59.9% reported purchasing the device themselves, despite not being of legal purchasing age (15.4% of total sample); across all device types, products were most often purchased in vape shops or online.
Across all devices, the prevalence of self-purchase of vaping devices among underage young adults in the Los Angeles area was high, and most were purchased from a vape shop or online. Tobacco control policies to prevent underage purchase of tobacco products-particularly among never smokers-are needed.
A high proportion of underage young adults reported owning their own vaping device and having purchased it themselves from a vape shop or online. Stronger tobacco control policies and better enforcement efforts are needed to successfully prevent underage purchase of tobacco products.
电子烟设备的快速发展使得青少年和年轻人的使用模式分析变得复杂。本研究描述了五种不同电子烟设备类别中使用、吸食物质和购买行为的流行率。
来自洛杉矶地区队列的 2505 名参与者（平均年龄 19.2，SD = 0.46）于 2018 年 6 月至 2019 年 10 月完成了在线调查。对于通过数字图像描绘的四种设备类型（任何 pod 式电子烟、cigalike、box-mod、电子烟笔）和 JUUL 电子烟，参与者报告了过去 30 天的使用情况、吸食的物质（主要是尼古丁、尼古丁和四氢大麻酚[THC]、主要是 THC、两者都没有）、设备的拥有情况（是/否），以及他们在哪里获得该设备（例如，自己购买、从朋友那里获得），如果购买了，购买地点（例如，电子烟店、在线）。
总体而言，44.9%的人报告曾使用过至少一种设备，26.2%的人报告过去 30 天内使用过至少一种设备。过去 30 天使用的流行率最高的是 pod 式电子烟（任何 pod = 17.0%；JUUL = 15.1%）。在报告曾拥有任何设备的受访者中（n = 643 [25.7%]），尽管未达到法定购买年龄（占总样本的 15.4%），但 59.9%的人报告自己购买了该设备；在所有设备类型中，产品最常从电子烟店或在线购买。
在洛杉矶地区，所有设备中，未成年年轻人自我购买电子烟设备的比例很高，而且大多数都是从电子烟店或在线购买的。需要制定烟草控制政策，防止未成年人购买烟草产品，特别是防止从未吸烟者购买。
相当一部分未成年年轻人报告拥有自己的电子烟设备，并从电子烟店或在线购买。需要更强大的烟草控制政策和更好的执法努力，以成功防止未成年人购买烟草产品。
