简介：这项研究调查了娱乐性大麻销售合法化和俄勒冈州县大麻零售供应是否与青少年中大麻使用和相关信仰的较高水平相关。方法：来自35个俄勒冈州县的2010-2018年学生健康调查的6年级、8年级和11年级学生的两年期数据（n= 247，403）在2019年进行了分析，以评估过去30天大麻使用和信仰的变化（例如，从2015年10月开始，允许在未合并地区销售娱乐性大麻的县与不允许的县相比，大麻的可获得性）。还对2016年和2018年学生健康调查数据进行了分析（n= 101，419）以确定允许娱乐性大麻销售和大麻使用之间的关联是否可以通过零售大麻出口密度和信念来解释。在过去的30年里，在允许在未合并地区销售娱乐性大麻的县，在2015年娱乐销售合法化之前和之后。在允许和不允许娱乐性大麻销售的县合法化后，过去30天大麻使用的流行率相对于下降的世俗趋势有所增加。在支持大麻使用的信念上也发生了类似的变化。2016年和2018年学生健康调查数据的分析表明，允许娱乐性大麻销售和过去30天的大麻使用之间的关联可以通过零售大麻出口密度和信念来解释。结论：合法化和娱乐性大麻的更大零售可用性与青少年大麻使用呈正相关。(C)2019年美国预防医学杂志。爱思唯尔公司出版All rights reserved.
Introduction: This study investigated whether legalization of recreational marijuana sales and retail availability of marijuana in Oregon counties were associated with higher levels of marijuana use and related beliefs among adolescents.Methods: Biennial data for 6th, 8th, and 11th graders from the 2010-2018 Student Wellness Survey in 35 Oregon counties (n=247,403) were analyzed in 2019 to assess changes in past 30-day marijuana use and beliefs (e.g., perceived availability of marijuana) in counties that allowed recreational marijuana sales in unincorporated areas beginning in October 2015 versus counties that did not. Analyses were also conducted with 2016 and 2018 Student Wellness Survey data (n=101,419) to determine whether the association between allowing recreational marijuana sales and marijuana use could be accounted for by retail marijuana outlet density and beliefs.Results: Higher rates of past 30-day marijuana use and more favorable beliefs were observed in counties that allow recreational marijuana sales in unincorporated areas, both before and after legalization of recreational sales in 2015. The prevalence of past 30-day marijuana use increased, relative to the downward secular trend, after legalization both in counties that did and did not allow recreational marijuana sales. There were parallel changes in beliefs favorable to marijuana use. Analyses with 2016 and 2018 Student Wellness Survey data suggested that the association between allowing recreational marijuana sales and past 30-day marijuana use could be accounted for by retail marijuana outlet density and beliefs.Conclusions: Legalization and greater retail availability of recreational marijuana are positively associated with marijuana use among adolescents.
