The Uniform Rights of the Terminally Ill Act (1985, revised 1989), has been recommended as a Uniform Act in the United States, and subsequently been passed by many states. The law allows a person to declare a living will specifying that, if the situation arises, he or she does not wish to be kept alive through life support if terminally ill and/or in a coma.

Many people make use of this act because they do not wish to endure any pain or suffering if weakened by a fatal disease. They want to "die with dignity," so that family members will not have to go through emotional pain of watching their loved one sleep through many years of life with no response to any stimuli.

This form of death is known as passive euthanasia, where death is not inflicted with drugs, but is allowed by cutting off life support.

See also Rights of the Terminally Ill Act (1995) of Australia's Northern Territory, which legalized euthanasia in certain cases until it was nullified by the federal Parliament.
