Assisted suicide is suicide with the aid of another person. In the United States, the term "assisted suicide" is typically used to describe what proponents refer to as medical aid in dying, in which terminally ill adults are prescribed and self-administer barbiturates if they feel that they are suffering significantly. The term is often used interchangeably with physician-assisted suicide (PAS), "physician-assisted dying", "physician-assisted death", "assisted death" and "medical aid in dying" (MAiD).
