Definition of Nitrogen narcosis

Nitrogen narcosis: A condition similar to intoxication with alcohol characterized by euphoria, loss of balance and manual dexterity, disorientation, and impaired reasoning. It can occur in scuba divers below 30 meters (100 feet) who breathe compressed air, because of the high nitrogen content of air. Nitrogen narcosis is reversed as the gas pressure decreases and the diver returns toward the surface.
