Which substance is classified as a depressant?

Caffeine
Nicotine
Heroin
Alcohol

The correct answer is: Alcohol

The substance classified as a depressant is alcohol. Depressants are substances that reduce the functioning of the central nervous system, leading to a decrease in brain activity, relaxation, and sedation. Alcohol, when consumed, can slow down bodily functions, leading to effects such as decreased inhibitions, slurred speech, impaired judgment, and overall sedation. In contrast, caffeine is a stimulant that increases alertness and energy levels; nicotine also acts as a stimulant, enhancing mood and concentration. Heroin, while an opioid with sedative properties, is typically categorized apart from depressants in the context of substance classification, as it primarily affects the brain's opioid receptors and can produce both depressant and euphoric effects. Nonetheless, when classifying based on the traditional depressant effects, alcohol is the clear choice.
