Depressants, such as benzodiazepines, barbiturates, and alcohol, slow down the central nervous system and can result in decreased brain and body activities. These drugs can induce relaxation, sedation, and drowsiness, and can also impair coordination, judgment, and reaction times. They are commonly used to treat conditions such as anxiety, insomnia, and seizures, but can also be misused for their calming and euphoric effects.
