Voluntary euthanasia is conducted with the consent of the patient. Active voluntary euthanasia is legal in Belgium, Luxembourg and the Netherlands. Passive voluntary euthanasia is legal throughout the US per "Cruzan v. Director, Missouri Department of Health". When the patient brings about their own death with the assistance of a physician, the term assisted suicide is often used instead. Assisted suicide is legal in Switzerland and the U.S. states of California, Oregon, Washington, Montana and Vermont.
