Was Sigmund Freud's death hastened?

The terminal illness of Sigmund Freud has been considered by many authors to be an example of physician-enacted euthanasia. A review and a reconsideration of the published literature by Freud's doctors and biographers cast doubt on this opinion. Over his last 48 h, Freud was administered substantial morphine doses to sedate and relieve his pain. However, from a pharmacological perspective, the timing of his death would not be consistent with that of a fatal dose of opioid. Freud died a natural death.
