We investigated whether recreational marijuana legalization (RML) in Oregon in 2015 and recreational marijuana and alcohol retail outlet density levels in Oregon counties were associated with increased alcohol and marijuana co-use and beliefs supportive of alcohol and marijuana use among adolescents. We conducted secondary analyses of biennial data collected from 11th graders who participated in the Student Wellness Survey (SWS) in 36 Oregon counties from 2010 to 2018 ( = 71,870). Multi-level logistic regression analyses assessed changes in past-30-day co-use of alcohol and marijuana, and alcohol- and marijuana-related beliefs after RML in counties with low, medium, and high densities of licensed recreational marijuana and alcohol retail outlets. We used post-RML 2016 and 2018 SWS data to examine whether beliefs accounted for any relationship of recreational marijuana and alcohol outlet density with alcohol and marijuana co-use. We found a significant post-RML increase in past-30-day alcohol and marijuana co-use in 2016 in counties with the highest density of recreational marijuana and alcohol retail outlets. There were significant post-RML increases in perceived risk and parent approval of alcohol and marijuana use. Analyses with 2016 and 2018 SWS data indicated that the relationship between level of recreational marijuana and alcohol retail outlet density and past-30-day alcohol and marijuana co-use was accounted for beliefs about marijuana and alcohol availability, approval by parents, and risk. RML and greater retail availability of recreational marijuana and alcohol were positively associated with alcohol and marijuana co-use among adolescents, and with beliefs favorable to alcohol and marijuana use.
我们调查了2015年俄勒冈州休闲大麻合法化（RML）以及该州各县休闲大麻和酒精零售店的密度水平是否与青少年中酒精和大麻共同使用增加以及支持酒精和大麻使用的观念有关。我们对2010年至2018年期间参与俄勒冈州36个县学生健康调查（SWS）的11年级学生收集的两年期数据进行了二次分析（n = 71,870）。多层次逻辑回归分析评估了在持有执照的休闲大麻和酒精零售店密度低、中、高的县，RML后过去30天内酒精和大麻共同使用情况以及与酒精和大麻相关的观念的变化。我们使用2016年和2018年RML后的SWS数据来检验这些观念是否解释了休闲大麻和酒精零售店密度与酒精和大麻共同使用之间的任何关系。我们发现，在休闲大麻和酒精零售店密度最高的县，2016年RML后过去30天内酒精和大麻共同使用情况显著增加。RML后，对酒精和大麻使用的感知风险以及父母的认可也显著增加。对2016年和2018年SWS数据的分析表明，休闲大麻和酒精零售店密度水平与过去30天内酒精和大麻共同使用之间的关系可以由对大麻和酒精可得性、父母认可以及风险的观念来解释。RML以及休闲大麻和酒精零售可得性的提高与青少年中酒精和大麻共同使用以及支持酒精和大麻使用的观念呈正相关。
