What do depressants primarily affect within the body?

Depressants primarily affect the central nervous system (CNS), particularly neurons, by slowing down brain activity and decreasing the speed of communication between the brain and the body. This leads to a calming effect on the mind and body, which can manifest as sedation, reduced anxiety, and relaxation. The mechanism through which depressants exert their effects often involves the enhancement of neurotransmitter activity, particularly gamma-aminobutyric acid (GABA), which inhibits neuronal activity.

While depressants do have some influence on other bodily systems, such as muscle coordination and cardiovascular functions, their primary action is on neuronal pathways. This is why understanding their impact on neurons is crucial for recognizing the broader implications these substances can have on overall bodily function and safety.
