The objective of this study is to assess the changes in rates of juvenile cannabis criminal allegations and racial disparities in Oregon after legalization of cannabis (July 2015) for adults.
This study included all allegations for cannabis-related offenses that occurred from January 2012 to September 2018 in Oregon. Negative binomial regression models were used to examine monthly cannabis allegation rates over time, and tested differences between youth of color and white youth, adjusting for age, gender, and month the allegation occurred. Analysis was conducted in January-March 2019.
Cannabis allegation rates increased 28% among all youth and 32% among cannabis-using youth after legalization. Rates of allegations were highest for American Indian/Alaska Native and black youth. Rates for black youth were double that of whites before legalization, and this disparity decreased after legalization. For American Indian/Alaska Native youth, rates were higher than whites before legalization, and this disparity remained unchanged.
Adult cannabis legalization in Oregon was associated with increased juvenile cannabis allegations; increases are not explained by changes in underage cannabis use. Relative disparities decreased for black youth but remained unchanged for American Indian/Alaska Native youth. Changing regulations following adult cannabis legalization could have unintended negative impacts on youth.
本研究旨在评估俄勒冈州成人大麻合法化(2015 年 7 月)后,青少年大麻犯罪指控率的变化和种族差异。
本研究包括 2012 年 1 月至 2018 年 9 月期间俄勒冈州所有与大麻相关犯罪的指控。使用负二项回归模型来检验随时间推移的每月大麻指控率,并调整年龄、性别和指控发生的月份,检验有色人种青年和白人青年之间的差异。分析于 2019 年 1 月至 3 月进行。
大麻合法化后,所有青少年和大麻使用者青少年的大麻指控率分别增加了 28%和 32%。美国印第安人/阿拉斯加原住民和黑人青年的指控率最高。大麻合法化前,黑人青年的指控率是白人的两倍,这一差距在合法化后有所缩小。对于美国印第安人/阿拉斯加原住民青年,其指控率高于白人,且这一差距在合法化前后保持不变。
俄勒冈州成人大麻合法化与青少年大麻指控增加有关;未成年大麻使用的变化无法解释这些增加。黑人青年的相对差异有所缩小,但美国印第安人/阿拉斯加原住民青年的差异保持不变。成人大麻合法化后的法规变化可能对青年产生意想不到的负面影响。
