If she was being treated for late stage cancer, opioids are going to show up in a tox screen, although dying at home and apparently alone says to me that she wasn’t being treated, otherwise she’d have been in hospice. It’s really pitiful and sad, what a way to go for a formerly beloved actress.
in my experience the oncologist prescribed far more opiates than I needed just to be sure. I am surprised that there were none found - she must have suffered terribly.
