Cannabis use has been more prevalent among men than women and prior work has found differing impact of recreational cannabis laws (RCL) by age. We examined changes in the prevalence of past-year and past-month cannabis use, past-month daily cannabis use, and DSM-5-proxy cannabis use disorder (CUD) in the past-year before and after RCL enactment by gender alone and stratified by age using 2008-2017 repeated cross-sectional samples of the US National Survey on Drug Use and Health. Changes in cannabis outcomes were estimated using adjusted multi-level logistic regression with state random intercepts and two-way and three-way interactions between RCL, gender, and age group. Enactment of RCL was associated with higher increases in past-year (+3.2%; aOR= 1.30 [95%CI = 1.19 to 1.41]) and past-month (+2.3; 1.37 [1.24 to 1.51]) cannabis use in women than men (+2.1%; 1.15 [1.06 to 1.25] and +1.7%; 1.19 [1.08 to 1.30]). No increases in past-month daily cannabis use and past-year DSM-5 CUD among those using cannabis were observed after RCL enactment. There were no increases in any cannabis outcomes after RCL enactment among those 12-20 years old. RCL enactment may contribute to narrowing of the cannabis gender gap. Ongoing surveillance is essential to ensure that the social justice aims of legalization are achieved without negative public health consequences.
大麻使用在男性中比女性更为普遍，先前的研究发现娱乐性大麻法律（RCL）对不同年龄人群有不同影响。我们利用2008 - 2017年美国国家药物使用和健康调查的重复横断面样本，单独按性别并按年龄分层，研究了RCL颁布前后过去一年和过去一个月大麻使用的流行率变化、过去一个月每日大麻使用情况以及DSM - 5代理大麻使用障碍（CUD）的变化。使用具有州随机截距以及RCL、性别和年龄组之间双向和三向交互作用的调整多水平逻辑回归来估计大麻使用结果的变化。RCL的颁布与女性过去一年（+3.2%；调整后比值比[aOR]=1.30[95%置信区间（CI）=1.19至1.41]）和过去一个月（+2.3；1.37[1.24至1.51]）大麻使用的增加幅度高于男性（+2.1%；1.15[1.06至1.25]和+1.7%；1.19[1.08至1.30]）相关。RCL颁布后，在使用大麻的人群中，过去一个月每日大麻使用和过去一年DSM - 5 CUD没有增加。在12 - 20岁的人群中，RCL颁布后任何大麻使用结果都没有增加。RCL的颁布可能有助于缩小大麻使用的性别差距。持续监测对于确保合法化的社会正义目标得以实现而不产生负面公共卫生后果至关重要。
