| According to the 2023 Monitoring the Future survey, 8th and 10th graders who reported seeing advertisements for marijuana on billboards were more likely to have used marijuana in the past year and the past month. Compared to those who never saw these marijuana billboards, those who reported seeing them more than once a day were 4 times more likely to have used marijuana in the past year and 7 times more likely to have used marijuana in the past month. We cross-referenced the questions that asked students how often they saw advertisements for marijuana on billboards, with the questions about whether they used marijuana. As the frequency of seeing advertisements for marijuana on billboards increased, the likelihood of using marijuana in the past year also increased: Not at all (9.8% used marijuana in the past year) Less than once a month (14.7% used marijuana in the past year) 1–3 times per month (15.1% used marijuana in the past year) 1–3 times per week (16.6% used marijuana in the past year) Daily or almost daily (20.4% used marijuana in the past year) More than once a day (41.6% used marijuana in the past year) |
