Which substance is categorized as a depressant in standard classifications of drugs?

• A. Alcohol
• B. Cocaine
• C. Cannabis
• D. PCP

Answer: (A)

The main idea is how drugs are grouped by how they affect the brain and body. A depressant slows down central nervous system activity. Alcohol does this by enhancing the brain’s inhibitory signals (GABA) and dampening excitatory activity, which leads to slower speech, poorer coordination, slowed reaction time, and impaired judgment. That classic slowing effect makes alcohol the standard example of a depressant in typical drug classifications. Cocaine, in contrast, is a stimulant that boosts CNS activity, increasing energy, alertness, and heart rate. PCP acts as a dissociative with perceptual distortions and analgesia rather than simply slowing the mind. Cannabis can have a mix of effects, but it isn’t the cleanest example of a depressant in standard classifications, whereas alcohol clearly fits the depressant profile.
