Drugs that excite neural activity and speed up body functions are called?

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

Answer: (C)

Stimulants are drugs that excite neural activity and speed up bodily functions. They boost alertness, energy, and physical activity, often by increasing neurotransmitters like dopamine and norepinephrine. That makes this term the best match for the description. In contrast, psychoactive drugs is a broad umbrella for substances that alter mental state, but it doesn’t specify the speed-up effect. Marijuana is a single drug with effects that are not primarily about stimulating the CNS, and opioids are depressants that slow bodily functions and dull pain. So the stimulant label fits best for “drugs that excite neural activity and speed up body functions.”
