Which symptom is generally not associated with stimulant use?

Decreased energy is generally not associated with stimulant use because stimulants are known for their energizing effects. These substances, such as amphetamines or cocaine, typically lead to an increase in physical energy and alertness. This is evident in the other symptoms listed, such as increased heart rate, heightened alertness, and increased talkativeness, all of which are common reactions to stimulant consumption. Users often experience heightened levels of excitement and activity, which can lead to a significant boost in energy levels, making decreased energy an unlikely symptom in the context of stimulant use.
