Background: There is a hypothesis that low socioeconomic status (SES) may explain the link between cannabis use and poorer academic performance and mental health. A key question, therefore, is whether adolescent cannabis use is associated with poorer academic performance and mental health in high SES communities where there is reduced potential for confounding.
Methods: Youth (n = 254) from an upper middle class community were followed prospectively through the four years of high school (from age 14/15 to age 17/18). Past-year frequency of cannabis use was assessed annually. Official school records of academic performance and self-reported mental health symptoms (externalizing and internalizing symptoms) were assessed in grades 9 and 12.
Results: Persistent cannabis use across the four years of high school was associated with lower grade-point average (beta = -0.18, p = .006), lower Scholastic Aptitude Test (SAT) score (beta = -0.13, p = .038), and greater externalizing symptoms (beta = 0.29, p Conclusions: Low SES cannot fully explain associations between cannabis use and poorer academic performance and mental health.
Cannabis use among high socioeconomic status (SES) students was associated with poorer grades.
Cannabis use was also associated with greater externalizing symptoms.
Associations persisted through adjustment for potential confounders.
Similar associations were observed for alcohol and tobacco use.
