E-cigarettes are the most popular tobacco product among youth. As more states adopt cannabis legalization policies, youth cannabis use in e-cigarettes is a mounting concern.
Data were from the 2016 and 2017 National Youth Tobacco Survey, a nationally-representative repeated cross-sectional survey administered to US middle and high school students. Ever use groups were categorized into e-cigarette ever users, cannabis in e-cigarette ever users, other tobacco ever users, and never users. Weighted multinomial logistic regression compared ever use groups, while controlling for state-level cannabis legalization and tobacco prevention polices, tobacco perceptions and exposures, and sociodemographic variables. Weighted prevalence of ever and current, or past 30 day, tobacco product use was determined by ever use groups.
Compared to e-cigarette ever users, cannabis in e-cigarette ever users increased (Adjusted Relative Risk Ratio (ARRR) = 1.65; p < 0.01) from 2016 to 2017. Medical-only and medical and recreational cannabis laws, and no e-cigarette minimum legal sales age (MLSA) and increased e-cigarette MLSA at 19 or 21 were positively associated with cannabis in e-cigarette ever users (ARRR = 1.34-1.85; p < 0.01, each). Ever and current use of all individual tobacco products was highest among cannabis in e-cigarette ever users compared to e-cigarette and other tobacco ever users.
Cannabis use in e-cigarettes has increased among youth, and these trends will likely continue as e-cigarettes continue to gain popularity and cannabis legalization policies proliferate. Targeted tobacco and cannabis prevention strategies are needed for youth, especially in states that have implemented cannabis 'medical and recreational laws.
电子烟是青少年最受欢迎的烟草产品。随着越来越多的州采用大麻合法化政策，青少年在电子烟中使用大麻的问题越来越令人担忧。
数据来自于 2016 年和 2017 年的全国青少年烟草调查，这是一项针对美国中学生和高中生进行的全国代表性重复横断面调查。曾经使用过的群体分为电子烟使用者、电子烟中含有大麻的使用者、其他烟草使用者和从未使用者。采用加权多项逻辑回归比较了曾经使用过的群体，同时控制了州级大麻合法化和烟草预防政策、烟草认知和暴露情况以及社会人口统计学变量。通过曾经使用过的群体确定了曾经和当前或过去 30 天内使用过的各种烟草制品的加权流行率。
与电子烟使用者相比，电子烟中含有大麻的使用者在 2016 年至 2017 年间有所增加（调整后的相对风险比（ARRr）=1.65；p<0.01）。仅医疗和医疗及娱乐性大麻法，以及没有电子烟最低法定销售年龄（MLSA）和提高 19 岁或 21 岁的电子烟 MLSA 与电子烟中含有大麻的使用者呈正相关（ARRr=1.34-1.85；p<0.01，每个）。与电子烟和其他烟草使用者相比，电子烟中含有大麻的使用者曾经和当前使用所有个体烟草制品的比例最高。
青少年中使用电子烟吸食大麻的现象有所增加，随着电子烟越来越受欢迎，大麻合法化政策不断增多，这种趋势可能会持续下去。需要针对青少年制定有针对性的烟草和大麻预防策略，特别是在已经实施大麻“医疗和娱乐性法律”的州。
