What is the typical effect of depressants on the pupil?

Explanation:
Depressants slow brain activity and don’t reliably alter the autonomic control of the pupil. Pupil size mainly changes in response to light and arousal through the balance of sympathetic (dilation) and parasympathetic (constriction) influences. While stimulants tend to dilate the pupils and opioids can constrict them, depressants don’t produce a consistent, drug-specific change in pupil size. So, the typical expectation is that depressants do not usually influence the pupil.
