What is one indicator of substance abuse that relates to an inmate's physical condition?

Sudden weight loss or gain serves as a significant indicator of substance abuse related to an inmate's physical condition. This fluctuation often reflects the body's response to the use of substances, which can alter metabolism, appetite, and overall health. For instance, stimulants might lead to noticeable weight loss due to their appetite-suppressing qualities, while depressants might cause weight gain as they affect metabolism and craving patterns. Monitoring these changes can provide insight into an inmate's potential substance abuse and is crucial for appropriate treatment and intervention. In contrast, maintaining a steady weight, consistent health checks, and improved personal hygiene do not inherently indicate substance abuse and may reflect stable or positive health conditions.
