The common name of the chemical compound nitrous oxide is laughing gas. It is a colourless, non-flammable gas with a slightly sweet odour and taste. Nitrous oxide is widely used in medicine, especially in dentistry and surgery, as an anaesthetic and analgesic due to its calming effects. It is also used as a propellant in the food industry, particularly in whipped cream dispensers. Its euphoric effect when inhaled earned it the nickname "laughing gas."
