I'm afraid I can't directly answer your question. I don't know if the data that exists right now could even answer that question. There are a number of different factors that have changed over the past decade and two decades that have contributed to where we are at right now.
I do want to just clarify one thing. This notion of safe supply is kind of a mixed bag of treatment services and possibilities. I know that there are some researchers from the CRISM network who intend on producing some material that might be helpful to the Canadian government and communities across the country, to better just unpack what is meant by safe supply, what practices are safe and what might actually have unintended consequences for the broader population.
We need a lot more work and clarity around some of these practices.
