What is a common effect of stimulant overdose?

A common effect of stimulant overdose is dehydration. Stimulants, such as amphetamines and cocaine, increase metabolic activity and can lead to elevated body temperature and excessive sweating. This increase in bodily temperature and activity can result in a significant loss of fluids. Additionally, stimulants often suppress appetite, which can contribute to a state of dehydration if the individual is not consuming adequate fluids.

While stimulant use might be associated with weight loss due to appetite suppression, this is more of a long-term effect rather than an acute effect of an overdose. Muscle gain is not typically an effect associated with stimulant use, especially in the context of overdose; rather, stimulants lead to increased energy and can sometimes lead to increased activity, but this does not translate into muscle gain as it would with strength training. Sleepiness is contrary to the action of stimulants, which are designed to increase alertness and energy, making it an unlikely effect in cases of overdose. Thus, dehydration stands out as a significant and common concern with stimulant overdose situations.
