The physiological effects of N2O (laughing gas, anaesthetic) and NO2 (acrid, corrosive fumes) have been known from the earliest days, and the environmental problems of NOj from automobile exhaust fumes and as a component in photochemical smog are well known in all industrial countries. 

Perhaps the best known oxide of nitrogen is N20, commonly called nitrous oxide or laughing gas. Nitrous oxide is frequently used as an anesthetic, particularly in dentistry. It is also the propellant gas used in whipped cream containers N20 is nontoxic, virtually tasteless, and quite soluble in vegetable oils. The N20 molecule, like all those in Figure 21.6, can be represented as a resonance hybrid. 

Nitrous oxide dissolves in the fats that sheath the nerve cells, and produces numbing and mild intoxication. It is the laughing gas dentists use to make patients less aware of pain.

Nitrous oxide is relatively soluble in water, and it is used as a propellant gas in canned whipped cream. It is also used as an anesthetic (laughing gas). 

LAUGHING GAS (And/Or Press, 1973) is the best reference on the psychedelic effects of nitrous oxide. N20 can be produced by heating ammonium nitrate at 240° until gas evolution ceases (the... 

Other greenhouse gases, include nitrous oxide (laughing gas), carbon tetrachloride, and several other minor gases. The collective greenhouse effect of these gases is estimated to add 50-150% to the increase in greenhouse effect expected from C02 alone. 

Dentists used to administer cyclopropane to their patients—its one of the several anesthetics used to put you to sleep. Others are nitrous oxide (laughing gas) and ether, which you will run into later on in this book. 

Diethyl ether was the inhalation anesthetic of choice during my childhood. Happily, 1 had rather little need of it. Ether was replaced years ago by a family of superior inhaled general anesthetics, most of which are ethane derivatives. The notable exception is another very simple molecule, nitrous oxide, N2O, frequently known as laughing gas. N2O has been around for a long time and was once a party drug. ...

Nitrous oxide, which is also called laughing gas, is a weak anesthetic. It is usually used together with hypnotics, analgesics, and muscle relaxants. It is sometimes called an ideal anesthetic because of the absence of any kind of suppressive influence on respiration. However, according to the latest information, use of nitrous oxide for more than 2 h is counterproductive since it causes a severe reduction of methionine synthesis, which in turn can cause a severe decrease in the level of vitamin Bj2 with all its subsequent consequences. 

Davy s research was to make him famous, not because he performed dangerous experiments, but because he discovered a new recreational drug. In 1800 he published a 580-page book titled Researches, Chemical and Philosophical, Chiefly Concerning Nitrous Oxide, or Dephlogisticated Nitrous Air, and Its Respiration in which he discussed his discovery of, and researches on, laughing gas. Describing its effects, Davy wrote ...
