Laughing gas is the common name for nitrous oxide or N2O.
It's a nonflammable, colorless gas that has a slightly sweet flavor and odor. In addition to its use in rockets and to boost engine performance for motor racing, laughing gas has several medical applications.
It has been used in dentistry and surgery as an analgesic and anesthetic since 1844, when dentist Dr. Horace Wells used it on himself during a tooth extraction. Since that time, its used has become commonplace in medicine, plus the euphoric effect from inhaling the gas has led to use as a recreation drug.
