I can start answering your questions, and Dr. Morissette can chime in.
Drug analysis has a number of objectives. The first is to give users in different places the opportunity to find out about the risks involved and the content of the drug that they're about to take. These drug sample tests help us understand the drugs currently going around and adjust our harm reduction strategies accordingly. This concerns both our public health organization and our partners.
Obviously, we carry out these tests in supervised consumption centres. However, we're conducting the tests in an increasingly wide variety of places. We even go to major festivals—Montreal is known as a festival city—where young people, including our children, often have the opportunity to use drugs. These drugs can be contaminated and fatal. We also use the tests to prevent overdoses in these places, especially since the people are occasional users.
