Which behavior is commonly associated with chemical impairment?

• A. Improved teamwork
• B. Extreme mood swings
• C. Calm demeanor
• D. Perfect attendance

Answer: (B)

When someone is chemically impaired, their emotions and behavior often become unstable because substances disrupt brain regulation of mood and impulse control. Extreme mood swings are a telltale sign, reflecting rapid shifts from calm to irritable, anxious, or tearful states and back again. This instability is typical of impairment and can be accompanied by other performance concerns, such as unreliable judgment and fluctuating work quality.

In contrast, improved teamwork and a perfectly calm demeanor with consistently good attendance would be inconsistent with impairment, and while a calm moment might occur, it doesn’t represent the pattern you’d expect with substance-related disruption. Recognizing mood volatility as a potential indicator helps ensure timely, confidential discussion with a supervisor and appropriate support for safety and well-being.
