Euthanasia is the practice of intentionally ending a life in order to relieve pain and suffering, while assisted suicide, also known as physician-assisted suicide, is suicide committed with the aid of a physician. Assisted suicide is often confused with euthanasia. In cases of euthanasia the physician administers the means of death, usually a lethal drug. In assisted suicide, it is required that the person voluntarily expresses their wish to die, and also makes a request for medication for the purpose of ending their life. Assisted suicide thus involves a person’s self-administration of deadly drugs that are supplied by a doctor.
