Which of the following symptoms is NOT commonly associated with depressant use?

Depressants, such as alcohol and benzodiazepines, are known to produce effects that slow down the central nervous system. Common symptoms associated with depressant use include disorientation, lack of coordination, and changes in pupil size, often resulting in constricted pupils.

Increased heart rate, however, is typically not a symptom associated with depressant use. Instead, depressants usually lead to a decrease in heart rate and lowered blood pressure due to their calming effects on the body's physiology. This makes the option about increased heart rate an accurate choice for the symptom that is not commonly associated with depressant use. Understanding these physiological effects is crucial for recognizing the signs of substance use and can profoundly inform the approach taken by those in juvenile justice fields when addressing substance-related issues among youth.
