Cannabis vaping may increase susceptibility to COVID-19 infection and related outcomes; however, little is known about the impact of the pandemic on cannabis vaping among US young populations. This study examined self-reported changes in cannabis vaping since the pandemic and factors associated with changes. A national, cross-sectional survey was conducted among 4,351 US adolescents and young adults (13-24 years old) in May 2020. Of those, 1,553 participants who reported ever vaping cannabis were included in the analytic sample. Binary outcome was self-reported increase in cannabis vaping (more hours/times of vaping in a day) vs. no change/quitting/reducing/switching. Weighted logistic regression examined associations between independent variables (i.e., risk perceptions of vaping, cannabis dependence, and stress/anxiety) and the outcome, controlling for sociodemographic factors. Overall, 6.8% reported increasing cannabis vaping since the pandemic, 37.0% quitting or reducing vaping in general, and 42.3% no change. Participants were more likely to report increased cannabis vaping if they perceived "Vaping is safer than smoking cigarettes" (Adjusted Odds Ratio [AOR] = 3.66; 95%CI = 1.43-9.38), reported more dependence on cannabis vaping (AOR = 1.59; 95%CI = 1.11-2.27), and were female (AOR = 2.80; 95%CI = 1.23-6.36). Those perceiving "Vaping cannabis can cause lung injuries" were less likely to increase cannabis vaping (AOR = 0.37; 95%CI = 0.18-0.76). Findings indicate that adolescent and young adult ever-cannabis vapers were more likely to report decreasing vaping generally than increasing cannabis vaping and most did not change use during the early pandemic. Educational campaigns should address potential health risks of cannabis vaping and focus on lung health to reduce use among young people during and following the pandemic.
吸食大麻电子烟可能会增加感染新冠病毒及出现相关后果的易感性；然而，对于疫情对美国年轻人群中大麻电子烟吸食情况的影响，我们却知之甚少。本研究调查了自疫情以来自我报告的大麻电子烟吸食变化情况以及与这些变化相关的因素。2020年5月，在美国4351名青少年和青年（13 - 24岁）中开展了一项全国性横断面调查。其中，1553名报告曾吸食过大麻电子烟的参与者被纳入分析样本。二元结局为自我报告的大麻电子烟吸食增加（一天中吸食时间/次数增多）与无变化/戒烟/减少吸食/改用其他方式。加权逻辑回归分析了自变量（即对电子烟吸食的风险认知、大麻依赖以及压力/焦虑）与结局之间的关联，并对社会人口学因素进行了控制。总体而言，6.8%的人报告自疫情以来大麻电子烟吸食增加，37.0%的人总体上戒烟或减少了吸食，42.3%的人无变化。如果参与者认为“吸电子烟比吸烟更安全”（调整后的优势比[AOR]=3.66；95%置信区间[CI]=1.43 - 9.38）、报告对大麻电子烟的依赖程度更高（AOR = 1.59；95%CI = 1.11 - 2.27）以及为女性（AOR = 2.80；95%CI = 1.23 - 6.36），那么他们更有可能报告大麻电子烟吸食增加。那些认为“吸食大麻电子烟会导致肺部损伤”的人增加大麻电子烟吸食的可能性较小（AOR = 0.37；95%CI = 0.18 - 0.76）。研究结果表明，与增加大麻电子烟吸食相比，曾吸食过大麻电子烟的青少年和青年更有可能报告总体上减少了吸食，并且在疫情初期大多数人的吸食情况没有变化。教育宣传活动应关注大麻电子烟的潜在健康风险，并聚焦肺部健康，以在疫情期间及之后减少年轻人的吸食行为。
