Which symptoms are indicative of stimulant intoxication?

Stimulant intoxication is characterized by various physical and psychological symptoms due to the effects of stimulants like amphetamines or cocaine on the central nervous system. Symptoms associated with stimulant intoxication typically include increased heart rate (tachycardia), elevated blood pressure, heightened alertness, and in some cases, psychotic features such as hallucinations.

In this context, tachycardia occurs as the body reacts to the stimulant’s stimulating properties, leading to increased heart rate. Hallucinations may arise due to the overstimulation of certain neurotransmitter systems, particularly dopamine, which can affect perception and cognition. Therefore, the presence of tachycardia and hallucinations aligns well with the typical manifestations of stimulant intoxication, making this the correct answer.

Other symptoms like fatigue, drowsiness, or low energy are contrary to what is seen with stimulant usage, as these substances generally lead to increased energy and alertness. Additionally, increased appetite and sleep disturbances are often associated with withdrawal from stimulants rather than intoxication, highlighting why other options do not fit the criterion for stimulant intoxication symptoms.
