At the individual level, covariates included self-reported sex, race/ethnicity (non-Hispanic White, non-Hispanic Black, non-Hispanic Native American/Alaska Native, non-Hispanic Asian/Native Hawaiian/Pacific Islander, Hispanic), age (20-29, 30-39, 40-49, 50+), past-year personal income ($0-19,999, $20-34,999, $35-69,999, >$70,000), education (some college versus high school or less), marital status (married versus single/widowed/separated/divorced), and urbanicity (living within a metropolitan statistical area versus not). Previous studies in these data have shown associations between these individual-level factors and marijuana use/disorder (Compton et al., 2005; Compton et al., 2004).
