What is a common indicator of narcotic use?

Droopy eyelids are a well-known symptom of narcotic use, especially with opioids. When individuals consume narcotics, these substances can depress the central nervous system, leading to drowsiness and sedation. The effect can cause the eyelids to appear heavy, which manifests as droopiness. This physical sign is often accompanied by other symptoms such as constricted pupils and a general sense of lethargy, further reinforcing a suspicion of narcotic use.

In this context, while other indicators such as thick slurred speech or difficulty in dividing attention may present with narcotic use, they are not as characteristic as droopy eyelids. Piloerection, or the involuntary bristling of hair on the skin, is more commonly associated with withdrawal symptoms rather than active use of narcotics. Thus, the droopy eyelids stand out as a direct and recognizable sign indicating current narcotic consumption.
