One of the recommendations in here was that we need to invest in what my colleagues from Health Canada were talking about, which is a good national drugs observatory, so that we truly understand the nature of the issue. I've heard it referred to. I forget where, but it's said that most drug crises are really a crisis of despair mapped upon an unsafe drug supply. When you put those two things together, you get a very toxic mixture that does great harm to our communities.
