^*Each adjusted binary logistic regression model included variables listed in the first column and controlled for study location (state). Less than 1% of the total sample and past 12-month substance users was not included due to missing data.

AOR: adjusted odds ratio. CI: confidence interval. Boldface: p<0.05.
