What type of drug slows down the central nervous system?

Depressants are substances that slow down the functioning of the central nervous system (CNS), which includes the brain and spinal cord. This category of drugs works by enhancing the effects of the neurotransmitter gamma-aminobutyric acid (GABA), leading to a calming effect on the body and mind. Common examples of depressants include alcohol, benzodiazepines, and barbiturates.

When the CNS is slowed down, it can lead to reduced anxiety, relaxation, and sedation. However, depressants can also impair motor skills, judgment, and reaction times, which can have dangerous consequences, especially when driving or operating machinery.

Other types of drugs mentioned, such as stimulants, typically increase CNS activity and can enhance alertness and energy. Narcotics primarily refer to pain-relieving medications that may also provide sedation but are categorized mainly by their pain-relieving properties rather than their overall influence on the CNS pace. Hallucinogens alter perception and can result in significant changes in thought processes and sensory perceptions but do not primarily act as central nervous system depressants.
