People use a lot of substances. They are polysubstance users, so it's not always that simple to just to treat one drug at a time. You heard that in Vancouver, 40% to 50% of people using one of the overdose prevention sites use methamphetamine. They probably use other drugs as well, so it's really quite a complex question you're asking. I'm not suggesting that we shouldn't look for the answers, but it's not just as simple as meth users per se.
