We are collecting data. We are evaluating programs. In terms of prescribed pharmaceutical alternatives, there are a number of studies under way. There are over 30 published evaluation results and some of them are quite promising.
The London study, as you mentioned, is one of them. The Ontario Drug Policy Research Network identified 20 publications and looked at promising outcomes, including reduced visits to emergency departments, reduced hospitalizations, reduced overdoses, reduced illegal drugs. There are a number of evaluations that have been undertaken by CIHR and the Canadian research initiative in substance misuse, CRISM, looking at the effectiveness of supervised consumption sites and of a number of different section 56 exemptions.
