Zero day subgroup includes never users and former users who reported no cannabis use in the 30 days prior to the interview.
Estimates adjusted for age (years), age squared and sex.
Estimates adjusted for age (years), sex, ethnic self-identification (non-Hispanic Whites, non-Hispanic Blacks, Hispanics, and all others), education (less than high school, high school, and above high school), poverty income ratio (<1 and ≥1), body mass index (kg/m2), alcohol drinking (never, former, and recently active), history of extra-medical drug use, and tobacco cigarette smoking (never, former, and recently active),
