Co-use of cannabis and tobacco poses greater risks than use of either substance individually and may be becoming more prevalent with increasing cannabis medicalization and legalization. We aimed to assess trends in the prevalence of cannabis and tobacco co-use between 2002-2019 and identify the updated prevalence and correlates of co-use in 2021 among US adults.
This study used data from the 2002-2021 National Survey on Drug Use and Health, a nationally-representative, cross-sectional survey in the US. We assessed prevalence trends in past 30-day cannabis and tobacco co-use, exclusive cannabis use, and exclusive tobacco use overall and by sociodemographic group using joinpoint regression. Additionally, multinomial models identified correlates of co-use in 2021.
In 2021, the weighted prevalence of cannabis and tobacco co-use was 6.38 %, the weighted prevalence of exclusive cannabis use was 7.28 %, and the weighted prevalence of exclusive tobacco use was 15.01 %. From 2002 to 2019, the prevalence of past 30-day co-use of cannabis and tobacco increased significantly (annual percentage change [APC]: 1.9 [1.4-2.4], P<0.05) among the overall US population. All subgroups of sex, race/ethnicity, and age also saw significant increases in co-use, other than young adults ages 18-25, for whom co-use was stagnant between 2002-2014 and then decreased significantly between 2014-2019.
This study identified increasing cannabis and tobacco co-use overall and among most sociodemographic strata in the US. As cannabis policy changes rapidly, co-use requires closer surveillance, clinical screening, and dedicated research.
大麻和烟草的共同使用比单独使用任何一种物质的风险都更大，而且随着大麻医疗用途的增加和合法化，这种共同使用的情况可能越来越普遍。我们旨在评估 2002-2019 年间大麻和烟草共同使用的流行趋势，并确定 2021 年美国成年人中这种共同使用的最新流行率和相关因素。
本研究使用了来自 2002-2021 年全国毒品使用与健康调查的数据，这是一项在美国进行的具有全国代表性的横断面调查。我们使用 joinpoint 回归评估了过去 30 天内大麻和烟草共同使用、单独使用大麻和单独使用烟草的总体流行趋势，并按社会人口统计学群体进行了评估。此外，多项模型确定了 2021 年共同使用的相关因素。
2021 年，大麻和烟草共同使用的加权流行率为 6.38%，单独使用大麻的加权流行率为 7.28%，单独使用烟草的加权流行率为 15.01%。从 2002 年到 2019 年，美国总人口中过去 30 天内大麻和烟草共同使用的流行率显著增加（年变化百分比[APC]：1.9[1.4-2.4]，P<0.05）。除了 18-25 岁的年轻人之外，所有性别、种族/族裔和年龄的亚组的共同使用也都显著增加，在 2002-2014 年期间，年轻人的共同使用率停滞不前，然后在 2014-2019 年期间显著下降。
本研究发现，美国总体以及大多数社会人口统计学群体中，大麻和烟草的共同使用都在增加。随着大麻政策的快速变化，共同使用需要更密切的监测、临床筛查和专门的研究。
