What can commonly indicate the use of narcotic analgesics aside from eye indicators?

The use of narcotic analgesics is often associated with a range of physiological and behavioral changes in an individual. One of the most notable effects of these substances is sedation and a general slowing of the body's processes, which can affect the perception of time, often referred to as the "internal clock." When someone is under the influence of narcotic analgesics, they may experience a slowed reaction to stimuli and a sense that time is passing differently than it normally would, indicating their impaired cognitive processing.

The other options do not align with the effects typically seen with narcotic analgesic use. Rather than exhibiting high energy and alertness, individuals may display lethargy and a lack of motivation. Clear speech is often compromised, as narcotics can lead to slurred speech or incoherence. Additionally, increased reflex actions are not characteristic of narcotic analgesic use; instead, these substances can dampen reflexes, resulting in sluggish responses.
