While several health risks of e-cigarette and marijuana use have been described, little is known about their associations with school-related outcomes and risky sexual behaviors in adolescents. : To determine the odds of adverse school outcomes and risky sexual behaviors among youth with single or dual use of e-cigarettes and marijuana. : We used data from the 2015 and 2017 waves of the Youth Risk Behavior Survey, a nationally representative survey of high school students in the US. Participants (=30,389) were divided into four exposure groups for single or dual use of e-cigarettes and marijuana. We compared rates of e-cigarette and/or marijuana use for different demographic characteristics using chi-square tests and performed multivariate logistic regressions exploring associations among e-cigarette and marijuana use and adverse school outcomes and risky sexual behaviors adjusting for confounding factors. : Participants reported e-cigarette-only (7.7%), marijuana-only (8.5%), and dual e-cigarette/marijuana (9.2%) use. Youth in all three use categories had higher odds of reporting grades that were mostly C's or lower than youth with no use, but no difference was found between youth with e-cigarette-only vs marijuana-only use. Increased odds of having sex without a condom were seen in youth with marijuana-only use (vs. e-cigarette-only use or no use) but not in youth with e-cigarette-only use or dual use. : We found increased odds of adverse school-related outcomes and contrasting sexual risk profiles among youth with single or dual e-cigarette and marijuana use.

虽然已经描述了电子烟和大麻使用的一些健康风险，但对于它们与青少年的学校相关结果和危险性行为之间的关联知之甚少。
确定青少年单独或同时使用电子烟和大麻与不良学校结果和危险性行为的几率。
我们使用了美国全国代表性的高中生青年风险行为调查 2015 年和 2017 年的两个波次的数据。参与者（n=30389）被分为电子烟和大麻单独或同时使用的四个暴露组。我们使用卡方检验比较了不同人口统计学特征的电子烟和/或大麻使用率，并使用多元逻辑回归，在调整混杂因素后，探讨了电子烟和大麻使用与不良学校结果和危险性行为之间的关联。
参与者报告了电子烟（7.7%）、大麻（8.5%）和同时使用电子烟和大麻（9.2%）。所有这三个使用类别的青少年报告的成绩主要为 C 或更低的几率高于没有使用的青少年，但电子烟与大麻单独使用的青少年之间没有差异。与电子烟单独使用或没有使用相比，大麻单独使用的青少年发生无保护性行为的几率增加，但电子烟单独使用或同时使用的青少年没有这种情况。
我们发现，青少年单独或同时使用电子烟和大麻与不良学校相关结果和不同的性风险特征有关。
