Which type of drug typically has a sedative effect?

CNS depressants are substances that have a sedative effect, which means they can induce relaxation, drowsiness, or a reduction in anxiety. These drugs work by slowing down brain activity and function, leading to a calming effect on the central nervous system. Common examples of CNS depressants include substances like alcohol, benzodiazepines, and barbiturates.

In contrast, CNS stimulants increase brain activity and can lead to heightened alertness, increased energy, and feelings of euphoria, which is the opposite effect of sedatives. Hallucinogens primarily affect perception and consciousness, creating altered sensory experiences rather than sedation. Inhalants can have a variety of effects depending on the substance, but many can also act as CNS depressants, though they are not typically classified solely as such. The distinguishing feature of CNS depressants lies in their primary action of inducing sedation, making them unique in their effects compared to the other drug classes in the list.
