Well, I'm not an expert on prevention. I'm an expert on treatment.
In Switzerland, we have very few young people initiating opioid use. We think part of it, and I tried to explain that before, is that the scale-up of treatment has made it very clear that it's quite dangerous to use opioids. There's a high risk you'll overdose, and you'll get addicted. There is also a high risk that you will end up in treatment.
I'm not sure whether that can be said for Canada with the treatment option I'm aware of, but in Switzerland, it's very clear. If you have an opioid addiction, you have to go into treatment. This is very unattractive. We are sure that this is part of what has been preventive. What has also been preventive is that, obviously, less opioids are being sold on the streets, because we provide more effective treatment than is done in other places.
I also think that most adolescents are aware of the dangers. They could probably get codeine, things like that, but it's harder to get, for example, pharmaceutical heroin on the streets. That's clear.
