背景：目前，只有四个州将21岁以上成年人使用大麻合法化。因此，人们对合法化对青少年大麻使用的影响知之甚少。目的：本研究探讨了大麻合法化如何影响青少年使用的频率和后果，在一个以学校为基础的，物质使用干预的参与者样本。我们假设，在大麻合法化后几年参加干预的青少年与之前参加的青少年相比，会出现更多的问题使用，并且大麻感知风险的变化将是问题使用的一种机制。方法：2010年至2015年，262名学生参加了以学校为基础的物质使用干预。习惯性饮酒和药物使用记录，酒精和药物使用后果问卷和决策平衡矩阵被用来评估大麻的使用频率，负面后果和感知风险。一个中介模型被用来测试大麻合法化可能导致增加使用频率和通过感知风险的后果的程度。结果：研究结果表明，大麻相关的后果和感知风险后合法化之间存在显着的正相关关系。尽管两组之间使用相对平等，合法化组的青少年经历了更高水平的感知风险和增加的负面后果。结论/重要性：由于大麻在美国的合法化地位不断上升，必须向成年人和青少年提供有关未成年人使用大麻的后果的心理教育。
Background: Currently, only four states have legalized recreational marijuana use for adults over 21years of age. Therefore, little is known about the influence that legalization will have on adolescent marijuana use. Objectives: This study examines how marijuana legalization has impacted the frequency and consequences of adolescent use in a sample of participants in a school-based, substance use intervention. We hypothesized that adolescents enrolled in the intervention in years after marijuana legalization would present with more problematic use compared to those enrolled prior, and that changes in the perceived risk of marijuana would be a mechanism of problematic use. Methods: Participants were 262 students enrolled in a school-based substance use intervention in 2010 to 2015. The Customary Drinking and Drug Use Record, Alcohol and Drug Use Consequences Questionnaire, and a decisional balance matrix were used to assess marijuana frequency, negative consequences, and perceived risk of use. A mediation model was used to test the degree to which marijuana legalization may lead to increased frequency and consequences of use through perceived risk. Results: Findings indicated a significantly positive correlation between marijuana-related consequences and perceived risk post legalization. Despite relatively equal use between both groups, adolescents in the legalization group experienced higher levels of perceived risk and increased negative consequences. Conclusions/Importance: Due to the rising legalization status of marijuana in the United States, it is imperative that psychoeducation is provided to adults and adolescents about the consequences of underage marijuana use.
