Depressants have which effect?

Depressants have which effect?

• A. Stimulate
• B. Slow Nervous System
• C. Increase Heart Rate
• D. Heighten Awareness

Answer: (B)

Depressants slow the central nervous system, reducing brain activity and leading to drowsiness, slower thinking, relaxed muscles, and calmer sensations. They dampen neural signaling, often by enhancing inhibitory neurotransmission (for example, alcohol increases GABA activity), which slows reflexes and overall mental processing. Because of this, heart rate and breathing can slow at higher doses, and alertness decreases. So the effect described is slowing the nervous system. The other options describe stimulation or heightened awareness, which are not traits of depressants.
