Inhalants are classified as central nervous system depressants because they primarily slow down brain function and bodily processes. When consumed, these substances can produce effects such as lightheadedness, euphoria, and sedation. This slowing can lead to decreased motor coordination and impaired cognitive functions, characteristics commonly associated with depressants.

On the other hand, CNS stimulants would increase activity and alertness, characteristic of substances like cocaine or amphetamines, which is not the effect of inhalants. CNS hallucinogens, such as LSD or psilocybin, lead to altered perceptions and experiences, which is also not what inhalants do. CNS antidepressants, typically referring to medications aimed at treating depression, work differently by influencing neurotransmitter levels but are not relevant to the category of inhalants. Thus, identifying inhalants as CNS depressants accurately reflects their primary effects on the central nervous system.
