The evidence we have is not necessarily related directly to opioids. It's related to people who come into supervised consumption sites to use those various products.
Indeed, you are right. There have been a fair number of studies done and we have a very good literature to indicate that supervised consumption sites overall reduce harms and don't increase crime. There's no increased level of activity around those sites.
The emergence of supervised consumption sites in Canada is relatively new, and we are collecting data. As part of the work we do with each supervised consumption site, we ask them to report in so that we'll be able to have a much better understanding as time flows about the use of methamphetamine and harms related to that.
What I can say is that if you are using a substance within a supervised consumption site, you have immediate access to harm reduction measures. While naloxone indeed works for opioids, having practitioners present if you're having another type of overdose is very helpful in terms of being able to call for help or for immediate assistance. Those harms we expect will be reduced, but there have been no studies directly related to that, to my knowledge. Michelle might be able to correct me on that.
I think the other piece that's interesting to note is that people who are using methamphetamines are using supervised consumption sites. I mentioned that in my remarks. In fact, we are seeing increased methamphetamine use at supervised consumption sites in Kelowna, as an example. In areas where opioid use had been quite prevalent, we are seeing some shifts happening, and we're monitoring that very closely.
The other piece related to supervised consumption sites and harm reduction, as you know, is that because methamphetamine is used in a whole variety of ways, including through injection drug use or sharing of products, the ability to have drug-related items available for people coming into supervised consumption sites drastically reduces the risk of any kind of infection happening. Furthermore, it often puts people into contact with direct treatment providers or other health care providers.
The ability for people to come into those supervised sites, whether they're using an opioid, methamphetamine or cocaine, means that they have access to a wide range of services. That's why we have been putting a real emphasis on trying to ensure that people are not using alone and that we're able to get help for them immediately if needed.
