Also known as laughing gas, nitrous oxide is often given to individuals during dentistry visits. It is also used for other purposes. It can be found in whippets, which are used to power whip cream dispensers. A high from nitrous oxide lasts only a short time and is very mild.

Poppers are alkyl nitrates that are inhaled for the purposes of getting high. Many people will purchase video head cleaners and air fresheners, both which contain alkyl nitrates, in order to inhale them and get high. They are often taken to intensify the user?s sexual experience.
