The gas commonly known as laughing gas is Nitrous oxide (N2O). It has anesthetic and analgesic properties, leading to its use in dentistry and surgery. Nitrous oxide can induce feelings of euphoria, which is why it is referred to as laughing gas. Additionally, it is utilized in various other fields, such as food preparation (in whipped cream dispensers) and as an oxidizer in rocket propellant systems. The gas is colorless and has a slightly sweet odor.
