To clarify, in some contexts we know exactly where it's coming from, because the investigation has borne that out through direct observations. In many cases, some of the drugs are being seized in their original packaging. Often, however, the identifying information, such as the original customer's name or location, has been scratched off of those bottles, and there's no tracing element that is put into safer-supply drugs. If those drugs are located outside a package or have been repackaged in a plastic bag, for example, we will not be able to determine their initial origin was.
