Which of the following is NOT a psychological effect of stimulants?

• A. Increased alertness
• B. Elevated mood
• C. Increased energy
• D. Muscle relaxation

Answer: (D)

Stimulants boost brain activity in the systems that control arousal and motivation. They raise levels of dopamine and norepinephrine, which enhances attention, energy, and mood. That’s why people often feel more alert, more energetic, and sometimes better mood after using stimulants. Muscle relaxation, however, isn’t a typical psychological effect of stimulants; in fact, stimulants can cause tension and jitters instead of relaxation. So the option describing muscle relaxation isn’t aligned with how stimulants usually affect the mind, while increased alertness, elevated mood, and increased energy are.
