assive and active euthanasia
Voluntary, non-voluntary and involuntary euthanasia can all be further divided into passive or active variants.[27] Passive euthanasia entails the withholding of common treatments, such as antibiotics, necessary for the continuance of life.[2] Active euthanasia entails the use of lethal substances or forces, such as administering a lethal injection, to kill and is the most controversial means. A number of authors consider these terms to be misleading and unhelpful.[2]
