This surge causes intense feelings of euphoria and increased energy. However, as the body metabolizes these neurotransmitters quickly, their levels drop sharply, often leading to feelings of fatigue, depression, and irritability. This dramatic decrease contrasts with the initial high and can create an overwhelming sense of crash known as a "comedown."

The rapid transition from an intense high to a low state can have significant psychological and physiological effects. It is not simply a result of the neurotransmitters being eliminated from the system; rather, it's also about how the body adapts to the sudden absence of these stimulating chemicals after they have been artificially elevated. This phenomenon describes one of the significant challenges associated with cocaine use and its impact on mental health.

Other options—prolonged euphoria, constant state of alertness, and enhanced cognitive function—do not accurately reflect the reality of post-cocaine use experiences. The initial euphoria may be compelling, but it
