Nang is a slang term commonly used in Australia to refer to a small balloon filled with nitrous oxide, also known as laughing gas. People often use these balloons for recreational purposes, inhaling the gas to experience a brief euphoric high. The practice has gained popularity at parties and music festivals, but it can pose health risks if misused. The use of nangs is often associated with the party culture and is sometimes linked to the consumption of other substances. While nitrous oxide is legal for certain uses, such as in medical settings or for food preparation, its recreational use can lead to legal and health concerns.
