Perception of health risk can influence household rules, but little is known about how the perception of harm from cannabis secondhand smoke (cSHS) is related to having a complete ban on in-home cannabis smoking. We examined this association among a nationally representative sample of United States adults.
Respondents were 21,381 adults from the cross-sectional Marijuana Use and Environmental Survey recruited from December 2019-February 2020. Perceived harm of cSHS exposure (extremely harmful, somewhat harmful, mostly safe, or totally safe) and complete ban of cannabis smoking anywhere in the home (yes or no) were self-reported. Logistic regression for survey-weighted data estimated covariate-adjusted odds ratios (OR) and 95% confidence intervals (CI) for the association between perceived harm of cSHS and complete ban on in-home cannabis smoking. Stratified subgroup analyses (by cannabis smoking status, cannabis use legalization in state of residence, and children under age 6 living in the home) were conducted to quantify effect measure modification of the association between perception of harm and complete ban.
A complete ban on in-home cannabis smoking was reported by 71.8% of respondents. Eight percent reported cSHS as "totally safe"; 20.5% "mostly safe"; 38.3% "somewhat harmful"; and 33.0% "extremely harmful". Those who reported cSHS as "extremely harmful" had 6 times the odds of a complete ban on in-home cannabis smoking (OR = 6.0, 95%CI = 4.9-7.2) as those reporting smoking as "totally safe". The odds of a complete ban were higher among those reporting cSHS as "somewhat harmful" (OR = 2.6, 95%CI = 2.2-3.1) or "mostly safe" (OR = 1.4, 95%CI = 1.2-1.7) vs those reporting cSHS as "totally safe". In each subgroup of cannabis smoking status, state cannabis use legalization, and children under the age of 6 living in the home, perceived harm was associated with a complete ban on in-home cannabis smoking.
Our study demonstrates perceiving cSHS as harmful is strongly associated with having a complete in-home cannabis smoking ban. With almost a third of US adults perceiving cSHS as at least "mostly safe", there is strong need to educate the general population about potential risks associated with cSHS exposure to raise awareness and encourage adoption of household rules prohibiting indoor cannabis smoking.
对健康风险的感知会影响家庭规则，但人们对大麻二手烟（cSHS）危害的感知与家中完全禁止吸食大麻之间的关系知之甚少。我们在一项具有全国代表性的美国成年人样本中研究了这种关联。
受访者是从 2019 年 12 月至 2020 年 2 月招募的横断面大麻使用和环境调查中的 21381 名美国成年人。对 cSHS 暴露的感知危害（非常有害、有些有害、基本安全或完全安全）和家中任何地方完全禁止吸食大麻（是或否）进行自我报告。对调查加权数据进行逻辑回归，以估计感知 cSHS 危害与家中完全禁止吸食大麻之间关联的校正后比值比（OR）和 95%置信区间（CI）。进行分层亚组分析（按大麻吸烟状况、居住地的大麻使用合法化以及家中 6 岁以下儿童），以量化感知危害与完全禁止家中吸食大麻之间关联的效应修正。
71.8%的受访者报告完全禁止在家中吸食大麻。8%的人报告 cSHS 为“完全安全”；20.5%的人报告“基本安全”；38.3%的人报告“有些有害”；33.0%的人报告“非常有害”。与报告吸烟完全安全的人相比，报告 cSHS“非常有害”的人完全禁止在家中吸食大麻的可能性要高出 6 倍（OR=6.0，95%CI=4.9-7.2）。与报告 cSHS 完全安全的人相比，报告 cSHS“有些有害”（OR=2.6，95%CI=2.2-3.1）或“基本安全”（OR=1.4，95%CI=1.2-1.7）的人更有可能完全禁止在家中吸食大麻。在大麻吸烟状况、州内大麻使用合法化和家中有 6 岁以下儿童的每个亚组中，感知危害与家中完全禁止吸食大麻有关。
我们的研究表明，认为 cSHS 有害与家中完全禁止吸食大麻有很强的关联。近三分之一的美国成年人认为 cSHS 至少是“基本安全”，因此需要对公众进行有关接触 cSHS 潜在风险的教育，以提高认识并鼓励采用禁止室内吸食大麻的家庭规则。
