Product		Weighted Abuse Prevalence*	Prevalence 95% CI	Relative Risk	P

CI = confidence interval; CRT = crush-resistant tablet formulations.

^*The denominator is the number of abusers of the product category by any route; the prevalence estimate is the cases per 100 abusers of product by any route.

^†See Table 1 for specific products within each category.

^‡Note that the relative risk values below 1 indicate that the comparator estimate is smaller than the reference product although the difference may or may not be significant. Relative risk values greater than 1 imply that the comparator estimate is greater than the reference.
