Divers who breathe oxygen fractions greater than in air (21%) need to be trained in the dangers of oxygen toxicity and how to prevent them. In order to buy nitrox, a diver has to show evidence of such qualification.
Since the late 1990s the recreational use of oxygen has been promoted by oxygen bars, where customers breathe oxygen through a nasal cannula. Claims have been made that this reduces stress, increases energy, and lessens the effects of hangovers and headaches, despite the lack of any scientific evidence to support them. There are also devices on sale that offer "oxygen massage" and "oxygen detoxification" with claims of removing body toxins and reducing body fat. The American Lung Association has stated "there is no evidence that oxygen at the low flow levels used in bars can be dangerous to a normal person's health", but the U.S. Center for Drug Evaluation and Research cautions that people with heart or lung disease need their supplementary oxygen carefully regulated and should not use oxygen bars.
Victorian society had a fascination for the rapidly expanding field of science. In "Dr. Ox's Experiment", a short story written by Jules Verne in 1872, the eponymous doctor uses electrolysis of water to separate oxygen and hydrogen. He then pumps the pure oxygen throughout the town of Quiquendone, causing the normally tranquil inhabitants and their animals to become aggressive and plants to grow rapidly. An explosion of the hydrogen and oxygen in Dr Ox's factory brings his experiment to an end. Verne summarised his story by explaining that the effects of oxygen described in the tale were his own invention. There is also a brief episode of oxygen intoxication in his "From the Earth to the Moon".

Famous quotes containing the words society and, society and/or culture:
“Who can measure the advantages that would result if the magnificent abilities of these women could be devoted to the needs of government, society and home, instead of being consumed in the struggle to obtain their birthright of individual freedom? Until this be gained we can never know, we can not even prophesy the capacity and power of women for the uplifting of humanity.”
—Susan B. Anthony (1820–1906)
“There is a city myth that country life was isolated and lonely; the truth is that farmers and their families then had a richer social life than they have now. They enjoyed a society organic, satisfying and whole, not mixed and thinned with the life of town, city and nation as it now is.”
—Rose Wilder Lane (1886–1965)
“As the traveler who has once been from home is wiser than he who has never left his own doorstep, so a knowledge of one other culture should sharpen our ability to scrutinize more steadily, to appreciate more lovingly, our own.”
—Margaret Mead (1901–1978)
