  • *Adjusted for age, gender, race/ethnicity, employment status, education, and other cannabis outcomes (i.e., most common mode of use is adjusted for typical times per day and typical days per week, typical times per day is adjusted for typical days per week and modes of use, and typical days per week is adjusted for typical times per day and modes of use).

  • Relative risk ratio estimated using a multinomial logistic regression model.

  • Relative risk estimated using a modified Poisson regression model.

  • Abbreviation: CI, confidence interval.
