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.
