Note: Percentages for mono and polydrug abuse are calculated from Total Users of each substance across rows and not down columns; n values are actual number of users. a This column reflects mono- and polydrug use for each particular substance category. Frequencies (N, %) do not add up to total users or 100% because of multiple responses among categories. b For each drug, odds ratio indicates the likelihood of the client's being a mono- or polydrug user when reporting that substance as the one requiring treatment. Odds ratios were estimated from bivariate logistic regression analysis; all were significant at p < 0.0001. c Other drugs refers mostly to club drugs, such as ecstasy, GHB, Ketamine, and Rohypnol. |
