Which symptom is part of stimulant intoxication?

Stimulant intoxication is characterized by a range of symptoms related to the effects of stimulants on the central nervous system. Hyperactivity is one of the primary symptoms associated with this state. When individuals are intoxicated with stimulants like amphetamines or cocaine, they often exhibit increased energy, heightened alertness, and a general sense of hyperactivity. This can manifest in behaviors such as rapid speech, excessive movement, and an elevated mood. These effects arise from the stimulants' ability to increase levels of certain neurotransmitters in the brain, particularly dopamine, which leads to increased arousal and activity levels.

In contrast, the other symptoms listed do not align with stimulant intoxication. Pupillary constriction is more commonly associated with opioids, hypotension can occur with various substances but is not typical of stimulants, and psychomotor retardation is associated with depressants rather than stimulants, which typically cause an increase in activity rather than a decrease. Understanding these distinctions is crucial for correctly identifying the symptoms of stimulant intoxication.
