What might a person under the influence of narcotics exhibit?

A person under the influence of narcotics often exhibits various physical signs and symptoms, one of which is a dry mouth. Narcotics, which include opioids, commonly cause dehydration and a reduction in saliva production, leading to the sensation of a dry mouth. This is a physiological effect associated with the action of these substances on the body's system, specifically affecting the autonomic nervous system.

In contrast, while an empty gaze might suggest sedation or altered mental status, it is not as directly linked to the physiological effects of narcotics as a dry mouth is. Fresh wounds do not relate to narcotic influence but could indicate other issues such as self-harm or violence. Rapid speech is generally associated with stimulant drug use, not narcotics, which tend to slow down metabolism and often result in lethargy or drowsiness. Understanding these distinctions helps in recognizing signs of substance influence accurately.
