Which eye indicator might be observed in someone under the influence of inhalants?

When assessing an individual under the influence of inhalants, one notable eye indicator is the presence of normal pupil size and reaction. In contrast to many other substances, such as stimulants or opioids, which often cause pronounced changes in pupil size—either dilation or constriction—inhalants typically do not produce such effects on pupil morphology. Instead, a person using inhalants may exhibit pupils that appear unaffected, maintaining a normal response to light.

This physiological response can be significant for law enforcement and medical personnel, as it provides insight into the substance affecting the individual. It also highlights the variability in the effects of different drugs, reinforcing the need for careful observation and evaluation when determining impairment or substance influence in various scenarios.
