You're talking about a very broad question when you talk about drug use in an institution. There are various indicators, such as seizures, but we also have other factors. We know through intelligence, for instance, that there may be drugs in the institutions but we haven't seized any. It's a very nebulous kind of question when we talk about drug use within the institution. How you measure that is a very difficult challenge.
