Which term refers to a class of substances that elevates mood and energy and can lead to dependence?

• A. Stimulants
• B. Marijuana
• C. Psychoactive Drugs
• D. Opioids

Answer: (A)

Elevating mood and energy by speeding up brain activity and boosting dopamine in the reward system describes stimulants. These substances increase alertness, energy, and euphoria, and their repeated use can lead to tolerance and dependence as the brain adapts to the heightened activity. Marijuana affects mood and perception but isn’t primarily about raising energy or wakefulness. The term psychoactive drugs is a broad category that includes many different effects, so it’s too general for this description. Opioids mainly provide pain relief and can produce euphoria, but they aren’t defined by increasing energy.
