Note: Problem status is binary variable (lower risk vs. high risk) based on definitions described previously for constructing composite risk score. Marj = marijuana. Note that significance level is influenced by distribution of problem status index

^†

First 12 variables and composite score are risk factors. Odds ratio >1 indicates second contrast group (e.g., dual users, Column 1) is at higher risk for problem status than first contrast group (e.g., single users, Column 1).

^‡

These two variables are protective factors. Odds ratio < 1 indicates second contrast group (e.g., dual users) is at higher risk for problem status than first contrast group (e.g., single users).
