Question: 1 / 640

Which of the following substances is primarily classified as a depressant?

Nicotine

Caffeine

Alcohol

Alcohol is classified primarily as a depressant because it slows down the function of the central nervous system. This leads to a range of effects including decreased anxiety, reduced inhibitions, and impaired motor skills. Depressants are substances that can reduce feelings of anxiety and induce relaxation or sedation, and alcohol exemplifies these characteristics.

In contrast, nicotine is a stimulant that can increase heart rate and energy levels. Caffeine also functions as a stimulant, enhancing alertness and energy. Mescaline, being a hallucinogen, primarily affects perception and can lead to altered states of consciousness and sensory experiences, rather than acting as a depressant. These differences in how each substance affects the body clarify why alcohol is the correct classification as a depressant.
