Which indicator of depressant use is described as appearing slow or lethargic?

Lethargy is a key indicator of depressant use, reflecting the slowed cognitive and motor functions that these substances can induce. When a person appears sluggish, it typically means they are showing a lack of energy and responsiveness, which aligns with the effects of depressants like alcohol and other sedative medications. This lethargy may manifest in their physical movements and mental alertness, making it evident that their system is being suppressed by the substance.

In contrast, other indicators focus on specific symptoms such as coordination issues, speech clarity, or mental clarity, which are also affected by depressants but do not encapsulate the general sense of fatigue or lack of energy. A person who is lethargic may still stumble (unsteady, staggering) or talk with slurred speech, but the defining characteristic here is that overt sluggishness in overall demeanor is the most apparent sign of depressant impact.
