Background: Marijuana use among adolescents is concerning in the United States, meanwhile, the effectiveness of school-based programs is inconclusive. This study examines the impact of school-based programs, school-based activities, and community-based activities on marijuana use among adolescents. Methods: A binary logistic regression analysis was conducted, using a sample of 16,509 adolescents (age = 12 to 17, male = 51.3%, White = 60.1%, Hispanic = 21.4%, African American = 14.7%, and Asian American = 3.9%) from the 2013 National Survey on Drug Use and Health (NSDUH). Results: Results of the main effects revealed that school-based programs, school-based activities, and community-based activities were deterrent factors against marijuana use among adolescents. Adolescents are less likely to use marijuana if they participate in school-based programs, school-based activities, and community-based activities. Conclusion: The findings of this study have implications for schools and those making educational policy.

背景：美国青少年吸食大麻的情况令人担忧，与此同时，学校计划的有效性尚无定论。本研究调查了校本计划、校本活动和社区活动对青少年吸食大麻的影响。方法：使用 16,509 名青少年样本（年龄 = 12 至 17，男性 = 51.3%，白人 = 60.1%，西班牙裔 = 21.4%，非裔美国人 = 14.7%，亚裔美国人 = 3.9%）进行二元逻辑回归分析) 来自 2013 年全国药物使用和健康调查 (NSDUH)。结果：主效应的结果显示，基于学校的计划、基于学校​​的活动和基于社区的活动是青少年吸食大麻的威慑因素。如果青少年参加基于学校的计划、基于学校​​的活动和基于社区的活动，则他们不太可能使用大麻。结论：这项研究的结果对学校和制定教育政策的人有影响。
