Perhaps I could take that.
SALOME was a study to assess long-term medication opioid use. The aim of the study was to compare the use of injectable pharmaceutical grade heroin or diacetylmorphine with the use of hydromorphone, an injectable form of a pain medication that's approved in Canada but not approved for use in opioid addiction at this point in time. The results of that study did show that, in the study population, hydromorphone was equally as effective as pharmaceutical grade heroin, and it did show some advantages in terms of adverse events.
However, that's one study and, obviously, that has to be taken into the context of the body of scientific and medical literature that is there.
