Which of the following is a withdrawal symptom of stimulants?

The withdrawal symptoms associated with stimulant use are characterized by a range of physical and psychological effects. In this case, decreased energy is a common withdrawal symptom seen when an individual stops using stimulants such as amphetamines or cocaine. During the period of withdrawal, individuals may experience fatigue, lethargy, and a general lack of vitality, which contrasts sharply with the heightened energy levels typically produced by stimulant use.

In withdrawal, the body reacts to the absence of stimulants, leading to changes in mood and energy. Individuals may feel significantly less motivated to engage in activities or complete tasks, which can further contribute to a cycle of decreased energy and motivation. This aspect of withdrawal can be particularly challenging, as it can affect various aspects of a person's life, including work, social interactions, and overall well-being.

The other choices, such as increased motivation, rapid speech, and enhanced focus, are more closely associated with the acute effects of stimulant use rather than withdrawal. During the active use of stimulants, individuals often exhibit these behaviors due to the drug's stimulating effects on the central nervous system. However, when withdrawing from stimulants, these effects diminish and are replaced by symptoms such as decreased energy.
