What is a common indicator of narcotic influence?

Droopy eyelids are a common indicator of narcotic influence because many narcotic substances have sedative effects that lead to drowsiness and relaxation of the body's muscles, including those around the eyes. When someone is under the influence of narcotics, they often exhibit physical signs of sedation, and droopy eyelids can be a visible manifestation of that state. This dilation or relaxed tension around the eyelids specifically signals that the individual may be experiencing the slowing down of central nervous system functions characteristic of narcotic use. Recognizing these physical cues is essential for those working in correctional environments, as it can help in identifying individuals who may be under the influence and need further assessment or intervention.
