A person who has taken an overdose of cocaine may experience which of the following reactions?

In cases of cocaine overdose, the most severe and possibly life-threatening reaction is death. Cocaine is a powerful stimulant that can have dire effects on the cardiovascular and central nervous systems. An overdose can lead to a range of critical conditions, including cardiac arrest, seizures, or significant increases in blood pressure and heart rate, which can result in fatal outcomes.

While increased energy, respiratory distress, and severe anxiety are indeed potential reactions associated with cocaine use or overdose, they do not encapsulate the extreme danger that the potential for death represents. This differentiates death as a more critical outcome that underscores the life-threatening nature of cocaine overdose and highlights the need for immediate medical intervention.
