In Tasmania, the term "nang" refers to small canisters filled with nitrous oxide, a compound with various applications. Nitrous oxide is legally sold in single-use silver canisters for balloons, and it is not prohibited by law in and of itself. However, the context in which they are used can dictate their legality, and the substance has a sinister side that young people may not be aware of. Nitrous oxide is one of the most commonly-used drugs among 16-24 year olds in England, and it is becoming increasingly popular in Australia. The sale of nangs in Australia is legal, and a pack of ten costs about AUD$10. Nitrous oxide bulbs are commonly referred to as nangs when used recreationally, and they are cheap and readily available. The bulbs or whippets are commonly referred to as ‘nangs’ due to the distorted and repetitive sound some people hear when the gas is inhaled. Inhaling nitrous oxide produces a rapid and short-lived rush of euphoria, happiness, or excitement, and other effects can include dissociation of the mind from the body, changes in thoughts, feelings, and perceptions, and visual and auditory hallucinations. Nitrous oxide bulbs are not very environmentally friendly, and used nangs should be placed in the bins supplied or disposed of properly to avoid littering.
