¹total number of observations used in the model; 150 were positive for drug abuse/dependence, 409 were negative and 221 observations were deleted due to missing values for the response or explanatory variables.

²Statistic presented is the t-value from an independent sample t-test comparison. Younger age, and being White, non-Hispanic were associated with having a drug use disorder. Fewer times homeless and fewer sexual partners were associated with not having a drug use disorder.

³Statistic presented is the Likelihood Ratio Chi-Square.
