The term for a drug that increases the action of the central nervous system, the heart, and other organs is?

• A. Addictive drug
• B. Stimulant
• C. Nicotine
• D. Carcinogen

Answer: (B)

Stimulant is the term for a drug that increases the action of the central nervous system, the heart, and other parts of the body. By boosting nerve signaling, stimulants raise alertness, energy, and focus, and they often increase heart rate and blood pressure as well. This is why substances like caffeine or nicotine are described as stimulants: they make the body work harder and faster for a period of time.

Other ideas aren’t describing the general effect: an addictive drug refers to a substance’s potential to cause dependence, not what it does to body systems; a carcinogen is any substance that can cause cancer; nicotine is a specific drug that is indeed a stimulant, but the question asks for the broad category that covers this action.
