本研究考察了青少年大麻使用和感知获取便利程度与县一级医用大麻卡数量的关系，以及2004年赞成医用大麻合法化的选民百分比所表明的大麻规范。采用层次线性模型分析蒙大拿州17482名青少年（13 - 19岁）的调查数据和县级档案数据，包括医用大麻合法化投票和医用大麻卡数量。居住在拥有更多医用大麻卡的县与终生或30天的大麻使用无关。然而，选民对医用大麻的认可与终身使用和30天使用呈正相关。大麻易获得度与医用大麻卡正相关，但当选民批准受控时，这种关系变得不显著。在大麻使用者中，大麻卡和选民批准与感知到的获取便利程度呈正相关。医用大麻卡与青少年使用大麻之间的关系可能与对大麻使用更宽容的整体规范环境有关。预防青少年使用大麻的干预措施应侧重于成年人对青少年使用和提供大麻的规范。
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. 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. 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. 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.
