Nitrogen narcosis can impair judgment similar to intoxication with which substance?

• A. Nicotine
• B. Marijuana
• C. Alcohol
• D. Caffeine

Answer: (C)

Nitrogen narcosis is a depth-related narcotic effect where the increased partial pressure of nitrogen depresses the central nervous system, leading to slower thinking, poor judgment, and impaired coordination. Those same kinds of cognitive and motor impairments are what you typically see with alcohol intoxication, which is why alcohol is the best match. Nicotine and caffeine are stimulants and tend to increase alertness, so they don’t resemble narcosis. Marijuana can impair perception and coordination too, but its profile isn’t the classic comparison used for nitrogen narcosis.
