Changes in Prevalence of Marijuana Consumption Modes Among Colorado High School Students From 2015 to 2017

Smoking is the most prevalent mode of marijuana consumption among adolescents, but nonsmoking modes, including ingesting, vaporizing, and dabbing, have expanded in the context of legalization. Each mode of consumption has different effects that may be associated with distinct health consequences. Previous research in Colorado identified smoking as the most commonly used mode of marijuana consumption among high school students and found that the prevalence of primarily ingesting marijuana declined after the implementation of retail marijuana sales. We examined changes in modes of marijuana consumption among high school students in Colorado from 2015 to 2017.
