Euthanasia - yooˌthənāˈzhə, either painlessly putting to death or failing to prevent death from natural causes in cases of terminal illness or irreversible coma. The term comes from the Greek expression for "good death." Technological advances in medicine have made it possible to prolong life in patients with no hope of recovery, and the term negative euthanasia has arisen to classify the practice of withholding or withdrawing extraordinary means (e.g., intravenous feeding, respirators, and artificial kidney machines) to preserve life. Accordingly, the term positive euthanasia has come to refer to actions that actively cause death. The term passive euthanasia is used when certain common methods of treatment, such as antibiotics, drugs, or surgery, are withheld or a large quantity of needed but ultimately lethal pain medication is supplied. By the end of the 20th cent. passive euthanasia was said to be a common practice among U.S. hospitals and physicians. With regard to euthanasia in animals, there are strict rules and guidelines that ensure ethical euthanasia and disposal.

Much debate has arisen in the United States among physicians, religious leaders, lawyers, and the general public over the question of what constitutes actively causing death and what constitutes merely allowing death to occur naturally. The physician is faced with deciding whether measures used to keep patients alive are extraordinary in individual situations, e.g., whether a respirator or artificial kidney machine should be withdrawn from a terminally ill patient. The Supreme Court's decision in Cruzan v. Director, Missouri Dept. of Health set a precedent for the removal of life-support equipment from terminal cases.

Popular movements have supported the legalization of the living will, a statement written by a mentally alert patient that can be used to express a wish to forgo artificial means to sustain life during terminal illness. In 1977, California became the first to pass a state law to this effect, known as the death-with-dignity statute.

Societies advancing the cause of positive euthanasia were founded in 1935 in England and 1938 in the United States. End-of-Life Choices (formerly the Hemlock Society) is one controversial group that has pressed for right-to-die legislation on a national level. Positive euthanasia is for the most part illegal in the United States, but physicians may lawfully refuse to prolong life when there is extreme suffering.

In the early 1990s, Dr. Jack Kevorkian, a Michigan physician, gained notoriety by assisting a number of people to commit suicide and became the object of a state law (1992) forbidding such activity. Kevorkian, who had been tried and acquitted repeatedly in the assisted deaths of seriously ill people, was convicted of murder in Michigan in 1999 for an assisted suicide that was shown on national television. Meanwhile, in 1997, the Supreme Court upheld state laws banning assisted suicide. In Oregon in 1994, voters approved physician-assisted suicide for some patients who are terminally ill; the law went into effect in 1997, following a protracted court challenge. In 2001 the Bush administration sought to undermine the law with a directive issued under the federal Controlled Substances Act, but Oregon successfully sued to prohibit the enforcement of it.

Since 1937 assisted suicide has not been illegal in Switzerland as long as the person who assists has no personal motive or gain. In 1993, the Netherlands decriminalized, under a set of restricted conditions, voluntary positive euthanasia (essentially, physician-assisted suicide) for the terminally ill, and in 2002 the country legalized physician-assisted suicide if voluntarily requested by seriously ill patients who face ongoing suffering. Belgium has also legalized (2002) euthanasia for certain patients who have requested it.
