Nitrous oxide, also known as "laughing gas," is a colorless and sweet-smelling gas that is often used as an anesthetic or a recreational drug. There are several synonyms for nitrous oxide, including: N2O, dinitrogen oxide, hyponitrous acid anhydride, and nitrogen (I) oxide. Nitrous oxide has a wide range of applications in several industries, including automotive, medical, and food. However, the recreational use of this gas is considered dangerous and can lead to serious health consequences. Despite its addictive properties, nitrous oxide continues to be a popular recreational drug due to its temporary and euphoric effects on the body and mind.
