What effects do depressants typically have on the body?

• A. Increase neurotransmission levels
• B. Lower neurotransmission levels
• C. Cause euphoria
• D. Create hallucinations

Answer: (B)

Depressants are substances that primarily slow down the activity of the central nervous system. They achieve this by enhancing the effect of neurotransmitters that inhibit neural activity, particularly gamma-aminobutyric acid (GABA). By increasing GABA's effectiveness, depressants lead to a decrease in the overall level of neurotransmission in the brain. This results in calming effects, reduced anxiety, and a sense of relaxation, but it can also cause sedation and impaired motor functions. The other choices present effects that are typically associated with different classes of substances. For instance, increasing neurotransmission levels aligns more closely with stimulants, which enhance alertness and energy. Euphoria is often associated with certain drugs like stimulants or some hallucinogens rather than depressants, which primarily induce relaxation or drowsiness. Hallucinations are characteristic of hallucinogens, which alter perception rather than diminish it, contrasting with the primary action of depressants.
