According to Richard Miech, the study’s principal investigator, nicotine vaping has topped cannabis and alcohol use among eighth-grade students for the past four years. The Monitoring the Future Study, which has been tracking substance use among children and adults since 1975, evaluates how often young people and adults use drugs. In comparison to 6% who had consumed alcohol and 5% who had consumed cannabis in the last 30 days, 7% of eighth graders in 2022 vaped nicotine.
