I can't say that it's the supply causing risk. It's because there are physicians who are prescribing it, and it's not the recommended line of treatment. In B.C., when safe supply first came in, it was for the administration of either tablets or injections of morphine under witnessed, supervised conditions three times a day.
Now, particularly in Ontario, it has degenerated into a daily dispensing of a day's supply of hydromorphone tablets, supposedly to be taken by the patient over the 24 hours, but we know full well, just by observation....
We can see that patients get their prescription of hydromorphone, take the first dose as a witnessed dose in front of the pharmacist and take the balance home. They're meant to take it throughout the day to prevent withdrawal and cravings, but instead, that is what they sell. It is diverted. That's where the danger is. It's not so much the supply that's then supplied in turn to the pharmacy; the problem stands with the physicians who are prescribing it.
