What physical sign may indicate narcotics use in an individual?

Flaccid muscle tone can indicate narcotics use in an individual due to the central nervous system depressant effects of these substances. Narcotics, such as opioids, decrease muscle tone and reflexes, leading to a state where the muscles appear relaxed and less responsive. This relaxation effect is a characteristic sign that can help identify potential narcotics use. When individuals are under the influence of narcotics, their body may exhibit a marked reduction in muscle stiffness, which is evident while observing them. Consequently, health professionals and law enforcement officers trained in recognizing signs of drug use can use this specific indicator when assessing individuals for potential narcotic intoxication.
