My Mother worked in the palliative unit and shared stories about how the staff regularly collectively decided to inform the patient that the button to administer morphine was in their control, and that they controlled enough dosage to peacefully end a person's life and so to be careful with it. Patients routinely ended their lives. This would have been in the late 80s, in Canada.
Since then Canada has legalized medically assisted dying; and I wonder if the increased regulation has made it _more difficult_ for patients to access it. No longer can a ward of palliative nurses simply opt to inform patients of their ability to die, but now those patients need the approval of doctors to do so.
