Which type of drugs are commonly referred to as "downers"?

The term "downers" commonly refers to depressants, which are substances that reduce the activity of the central nervous system. These drugs have a calming effect on the body and can induce sedation or relaxation. Depressants include medications such as benzodiazepines, barbiturates, and alcohol. They are often prescribed for anxiety, sleeping problems, and muscle relaxation, but can also lead to a decreased level of awareness and impaired coordination when abused.

In contrast, stimulants increase the activity of the central nervous system and can lead to heightened alertness and energy, while hallucinogens primarily induce altered perceptions and can create sensory distortions. Narcotics, typically opioid analgesics, are primarily used to manage pain and can have sedative effects, but they are not broadly categorized as "downers." Therefore, the classification of depressants as "downers" accurately reflects their effects on the user's mood and physical state.
