Population-level predictions from cannabis risk perceptions to active cannabis use prevalence in the United States, 1991-2014.

ABSTRACT: INTRODUCTION:A mosaic of evidence links risk perceptions with drug use in adolescence, including population summaries to guide public health campaigns, as well as subject-specific estimates on preventing an adolescent's drug use by manipulating that individual's prior risk perceptions. We re-visit these issues with a public health perspective, asking whether population-level cannabis risk perceptions of school-attending adolescents at one grade level might predict cannabis use prevalence two and four grade levels later. METHODS:From 1991 to 2014, each year's United States "Monitoring the Future" (MTF) study population included 8th-, 10th-, & 12th-graders. Two and four years later, statistically independent school samples of the same cohorts were drawn and assessed (n ~ 16,000/year). Popula
