What is a common symptom of stimulant use?

Reduced fatigue is indeed a common symptom of stimulant use. Stimulants, such as amphetamines and cocaine, increase levels of certain neurotransmitters in the brain, particularly dopamine and norepinephrine. This activity enhances alertness, attention, and energy levels, leading individuals to experience a reduction in feelings of fatigue.

Unlike sedatives or depressants, which can induce drowsiness, stimulants counteract tiredness and give users an increased sense of wakefulness and energy. This effect is often why stimulants are misused in various contexts, such as for studying or working longer hours without rest.

Other options, such as constricted pupils, increased appetite, and sluggishness, are generally associated with different categories of substances. Constricted pupils are more typical of opioid use, increased appetite is often seen in the context of certain depressants or when stimulant effects wear off (known as a "crash"), and sluggishness is commonly related to the effects of depressants rather than stimulants.
