On the latter, I'll leave it to Dr. Butler Jones to answer that one.
Certainly, the trend has been to what is called “medicalize” illicit injection drugs, and perhaps other drugs as well. By that, what we are saying is that somehow this is a health choice. It's not a health choice; it's an addiction. Call it what it is: it's an addiction, not a health choice. It leads to very unhealthy consequences. To call it a “medical choice” or a “health choice” really condemns people to a slow, painful, and terrible death. I don't want to do that, and I don't think any Canadian wants to do that.
In terms of the second question, I don't know if Dr. Butler Jones wants to weigh in on that.
