What psychological sign may indicate drug abuse in inmates?

Unexplained changes in personality or attitude are a significant psychological sign that may indicate drug abuse in inmates. Drug abuse can lead to profound alterations in an individual’s behavior and emotional state. For instance, an inmate might experience mood swings, increased irritability, paranoia, or withdrawal from social interactions, which may be unexpected compared to their usual behavior.

These changes typically occur due to the effects of the substances being abused. Drugs can alter brain chemistry and impact cognitive functions and emotional regulation, leading to behaviors that might seem sudden or uncharacteristic for the individual. Observing these changes can be crucial for identifying potential substance abuse issues within a correctional environment, allowing for appropriate interventions or support to be initiated.

The other options do not align with common signs associated with drug abuse. Increased collaboration and improved focus and motivation may indicate positive changes, while a calm demeanor at all times is generally not reflective of the tumultuous emotional states often brought about by substance use.
