What characteristic might a drug abuser deeply under the influence of narcotics display?

A drug abuser deeply under the influence of narcotics often shows lethargy as a key characteristic. This condition results from the depressant effects that many narcotics, such as opioids, have on the central nervous system. Users may appear drowsy, slow-moving, and may have difficulty maintaining alertness or focus. Lethargy indicates a significant suppression of normal physical and mental activity, which is a common reaction to the consumption of these substances.

In contrast, anxiety and hostility might be more associated with different types of substance use or withdrawal states. On the other hand, lucidity, which implies clarity of thought and awareness, is typically not present in individuals severely affected by narcotics, as they are generally in a stuporous or altered state of consciousness.
