Nitrogen Narcosis

Overview :

Nitrogen narcosis, commonly referred to as rapture of the deep, typically becomes noticeable at 100 ft underwater and is incapacitating at 300 ft, causing stupor, blindness, unconsciousness, and even death. Nitrogen narcosis is also called the martini effect because divers experience an effect comparable to that from one martini on an empty stomach for every 50 ft of depth beyond the initial 100 ft.
