The end of convergence in developmental patterns of frequent marijuana use from ages 18 to 30: An analysis of cohort change from 1976-2016

Previous research has shown that marijuana use prevalence typically increases from late adolescence through the early years of young adulthood (roughly ages 21/22) and then decreases thereafter (Bachman et al., 1997;Substance Abuse and Mental Health Services Administration (SAMHSA), 2017; Schulenberg et al., 2005, 2017; Terry-McElrath and O ’Malley, 2011). Trends in age-specific marijuana use prevalence clearly indicate marked changes across historical time (Centers for Disease Control and Prevention [CDC], 2015; Johnson et al., 2015; Miech et al., 2017;Substance Abuse and Mental Health Services Administration (SAMHSA), 2017; Schulen berg et al., 2017), but few studies have examined the extent to which the typical developmental pattern of marijuana use prevalence across age changes over historical time.
