Which factor might indicate drug use among inmates?

The correct choice highlights that both changes in sleeping patterns and unusual physical demeanor can be indicators of drug use among inmates. When inmates are using drugs, they often experience significant alterations in their behavior and physical condition.

Changes in sleeping patterns can manifest as insomnia or excessive sleepiness, both of which can result from substance use. For instance, stimulants like methamphetamines can cause reduced sleep, while depressants may lead to increased sleep.

Unusual physical demeanor can encompass a range of observable behaviors, such as erratic movements, excessive agitation, or lethargy, which also may suggest substance use. These signs are crucial for jail officers to recognize as they can impact the safety and management of the inmate population.

In contrast, consistent and cooperative behavior typically does not indicate drug use. In fact, it can often suggest that an inmate is functioning normally and may not be under the influence of substances at that moment. Understanding the significance of these behaviors is essential for jail officers in maintaining order and safety within the facility.
