What is a common indicator of narcotic use associated with frequent face scratching?

Facial itching is commonly associated with narcotic use due to the side effects these substances can have on the body. Narcotics can cause dry skin or allergic reactions, leading to discomfort and a compulsion to scratch the face frequently. This behavior might also stem from heightened sensitivity or an altered perception of itchiness, which can occur with the use of opioids. Recognizing facial itching as an indicator can be essential for peace officers in identifying potential narcotic use in individuals.

While other signs such as an increase in appetite, changes in sleep patterns, or weight loss might also relate to substance use, they are not specifically linked to frequent face scratching as prominently as facial itching is.
