Marijuana Use among Young Adults: Findings from the 2015-2018 National Survey on Drug Use and Health

Abstract

Marijuana is the most commonly used drug for young adults. A greater understanding of risk factors associated with recent use can inform health prevention messaging. Pooled data from the 2015-2018 National Survey on Drug Use and Health were utilized among 89,446 individuals ages 18-34. Weighted logistic regression analyses, controlling for covariates, were utilized to determine conditional associations to past-30-day use. A sizeable percentage (18.5%) of individuals reported smoking marijuana in the past 30 days. Individuals who identify as African American or Multi-Racial, Gay/Lesbian, Bisexual, reported their health as poor, not covered by health insurance, reported prior drug use, or who had reported any thoughts/plans of suicide were at risk for use. Of concern, high rates of alcohol (14.7%) and cocaine (1.50%) were found among users. We believe our findings can inform harm reduction efforts and policy creation.
