Shown are the estimates from the multivariable logistic regression models estimating the odds of: a) any past-year cannabis use vs. non-use in the entire sample (n = 47,569), and b) of higher vs. lower frequency of use in the sub-sample of current users (n = 7,232) as a function of all shown variables. Use frequency reflected less frequent use (≤50 times) and more frequent use (>50 times, up to daily use) in the past year.
