Secondhand tobacco smoke is associated with worsening asthma symptoms among children. However, the relationship between secondhand marijuana smoke and asthma symptoms among youth has not been examined. This study compares the prevalence of secondhand tobacco and marijuana smoke exposure, overall and by asthma status, among middle and high school students.
The study assessed participants of the 2019-2020 California Student Tobacco Survey: a large, cross-sectional random sample of 8th, 10th, and 12th graders (N = 158,937). Descriptive analyses examined exposure to combustible tobacco and marijuana secondhand smoke by students' asthma status and sociodemographic characteristics.
More students with asthma were exposed to combustible tobacco secondhand smoke (13.4 %) and marijuana secondhand smoke (12.0 %) than students without asthma (10.9 % and 9.3 %, respectively). The prevalence of secondhand marijuana smoke exposure was higher among 12th grade students (12.2 %) while the prevalence of secondhand tobacco smoke exposure was higher among 8th grade students (13.4 %) and those who lived in rural locations (15.4 %).
California students are exposed to marijuana secondhand smoke at similar proportions to combustible tobacco secondhand smoke and more students with asthma are exposed to marijuana secondhand smoke. These results expand the public health issue of secondhand smoke exposure among children with asthma by highlighting the need to examine marijuana secondhand smoke. Given the rapid shift in marijuana laws across the US, exposure to secondhand marijuana smoke is likely to increase. Therefore, vulnerable populations, such as children with asthma, should be prioritized for interventions that aim to alleviate secondhand marijuana exposure.
二手烟草烟雾与儿童哮喘症状加重有关。然而，青少年二手大麻烟雾与哮喘症状之间的关系尚未得到研究。本研究比较了初中和高中学生中二手烟草和大麻烟雾暴露的总体患病率以及按哮喘状况划分的患病率。
该研究评估了2019 - 2020年加利福尼亚州学生烟草调查的参与者：一个由八年级、十年级和十二年级学生组成的大型横断面随机样本（N = 158,937）。描述性分析按学生的哮喘状况和社会人口学特征检查了可燃烟草和大麻二手烟雾的暴露情况。
与无哮喘的学生相比，更多患有哮喘的学生暴露于可燃烟草二手烟雾（13.4%）和大麻二手烟雾（12.0%）（无哮喘学生分别为10.9%和9.3%）。十二年级学生中二手大麻烟雾暴露的患病率较高（12.2%），而八年级学生（13.4%）和居住在农村地区的学生（15.4%）中二手烟草烟雾暴露的患病率较高。
加利福尼亚州学生暴露于大麻二手烟雾的比例与可燃烟草二手烟雾相似，且更多患有哮喘的学生暴露于大麻二手烟雾。这些结果通过强调检查大麻二手烟雾的必要性，扩展了哮喘儿童二手烟雾暴露这一公共卫生问题。鉴于美国各地大麻法律的迅速变化，二手大麻烟雾暴露可能会增加。因此，对于旨在减轻二手大麻暴露的干预措施，应优先考虑哮喘儿童等弱势群体。
