AIMS
This study examined the relationship of youth marijuana use and perceived ease of access with the number of medical marijuana cards at the county-level, and marijuana norms as indicated by percent of voters approving legalization of medical marijuana in 2004.
METHODS
Survey data from 17,482 youths (ages 13 - 19) in Montana and county-level archival data, including votes for the legalization of medical marijuana and the number of medical marijuana cards were analyzed using hierarchical linear modeling.
FINDINGS
Living in a county with more medical marijuana cards was not related to lifetime or 30 day marijuana use. However, voter approval of medical marijuana was positively related to lifetime and 30 day use. Perceived ease of access to marijuana was positively related to medical marijuana cards, but this relation became non-significant when voter approval was controlled. Among marijuana users, marijuana cards and voter approval were positively related to perceived ease of access.
CONCLUSIONS
The relation between medical marijuana cards and youth use may be related to an overall normative environment that is more tolerant of marijuana use. Interventions to prevent youth marijuana use should focus on adult norms regarding use by and provision of marijuana to youths.
目的
本研究考察了县级医用大麻卡数量、2004年医用大麻合法化选民支持率所表明的大麻规范与青少年大麻使用及感知获取难易程度之间的关系。
方法
使用分层线性模型分析了来自蒙大拿州17482名青少年（年龄在13 - 19岁之间）的调查数据以及县级档案数据，包括医用大麻合法化投票情况和医用大麻卡数量。
结果
生活在拥有更多医用大麻卡的县与终生或30天内大麻使用无关。然而，选民对医用大麻的支持与终生和30天内使用呈正相关。感知获取大麻的难易程度与医用大麻卡呈正相关，但在控制选民支持率后，这种关系变得不显著。在大麻使用者中，大麻卡和选民支持与感知获取难易程度呈正相关。
结论
医用大麻卡与青少年使用之间的关系可能与对大麻使用更宽容的总体规范环境有关。预防青少年大麻使用的干预措施应侧重于成年人关于青少年使用大麻及向青少年提供大麻的规范。
