As of 2019, the drug enjoys moderate popularity in some countries. In the United Kingdom, as of 2014, nitrous oxide is estimated to be used by almost half a million young people at nightspots, festivals and parties. Officials in Norfolk, Hertfordshire and Thames Valley had reported increasing numbers of discarded
whipped-cream chargers being found.

Methods of inhalation[edit]
Recreational users generally use 8 gram containers of nitrous oxide "whippets", which they use to fill balloons or whipped cream dispensers. The gas is then inhaled from the balloon or dispenser.
[8] This is necessary because nitrous oxide is very cold when it undergoes
adiabatic decompression on exit from a canister; inhalation directly from a tank is dangerous and can cause
frostbite of the
larynx. Some users attach gas masks or other inhalation devices to large tanks of the gas.
In Australia, nitrous oxide bulbs are known as "nangs", possibly derived from the sound distortion perceived by consumers.
