Cannabis vaping, and co-use with cannabis smoking, can exacerbate the risks of developing respiratory diseases and cannabis dependence. This study aims to examine the mental health profiles and sociodemographic correlates of adults who vape cannabis and engage in dual cannabis use (vaping/ smoking), compared to those who smoke cannabis.
The most recent, cross-sectional wave of the Population Assessment of Tobacco and Health Study (Wave 6) was used in this study. Data were restricted to adults (18 + years) who currently use cannabis (n = 7,178). Participants were classified as 'cannabis smoking only,' 'cannabis vaping only,' 'dual-use,' or 'other cannabis use methods only.' Multinomial logistic regression was used to examine the sociodemographic, internalizing and externalizing symptom factors of cannabis vaping and dual-use compared to cannabis smoking.
Over 56 % of participants currently smoked cannabis only, 9.1 % vaped cannabis only, while 20.0 % were engaging in dual-use. Adults experiencing severe externalizing symptoms (vs. mild symptoms) had higher odds of engaging in dual-use than smoking cannabis only (OR = 1.89, 99.5 %CI: 1.48, 2.40). Those with White racial background (vs. African-American background) (OR = 3.90, 99.5 %CI: 2.31, 6.58) and earning a higher income (vs. lower income) (OR = 2.56, 99.5 %CI: 1.79, 3.66) had higher odds of currently vaping cannabis only, compared to smoking cannabis only.
Our study has identified that mental health plays a significant role in cannabis use patterns, particularly with externalizing symptoms which are related to aggression and diagnoses of attention deficit disorders. This highlights the need for healthcare and mental health providers to address mental health symptoms when managing adult cannabis use.
吸食大麻电子烟以及同时吸食大麻，会加剧患呼吸道疾病和大麻依赖的风险。本研究旨在考察吸食大麻电子烟及同时使用两种大麻吸食方式（电子烟/传统烟）的成年人的心理健康状况和社会人口学相关因素，并与吸食传统大麻的成年人进行比较。
本研究使用了烟草与健康人口评估研究的最新横断面数据（第6波）。数据仅限于目前使用大麻的成年人（18岁及以上）（n = 7178）。参与者被分为“仅吸食传统大麻”“仅吸食大麻电子烟”“同时使用两种方式”或“仅使用其他大麻吸食方式”。采用多项逻辑回归分析，考察与吸食传统大麻相比，吸食大麻电子烟及同时使用两种方式的社会人口学、内化和外化症状因素。
超过56%的参与者目前仅吸食传统大麻，9.1%仅吸食大麻电子烟，而20.0%同时使用两种方式。出现严重外化症状的成年人（与轻度症状相比）同时使用两种方式的几率高于仅吸食传统大麻（比值比[OR]=1.89，99.5%置信区间[CI]：1.48，2.40）。与非裔美国人背景相比，具有白人种族背景的人（OR = 3.90，99.5%CI：2.31，6.58）以及收入较高的人（与低收入相比）（OR = 2.56，99.5%CI：1.79，3.66），与仅吸食传统大麻相比，目前仅吸食大麻电子烟的几率更高。
我们的研究发现，心理健康在大麻使用模式中起着重要作用，特别是与攻击性和注意力缺陷障碍诊断相关的外化症状。这凸显了医疗保健和心理健康服务提供者在管理成年人使用大麻时应对心理健康症状的必要性。
