Which substances can impair judgment and reflexes affecting job performance?

The correct answer highlights that both prescription and over-the-counter drugs can impair judgment and reflexes, which are critical to job performance. Many medications, whether they are prescribed by a doctor or available without a prescription, have side effects that can include drowsiness, dizziness, decreased concentration, and impaired motor skills. This can be true for common medications such as antihistamines, pain relievers, and certain mental health medications. It’s important for individuals to be aware of how these substances may affect their ability to perform tasks safely and effectively in the workplace.

In contrast, illegal drugs, while they can certainly impair judgment, are not the only substances of concern. Natural supplements may also not have well-documented effects and may not always impair performance, making the answer incomplete. Excessive water intake, although it can lead to a condition called hyponatremia, normally does not impair judgment in the same immediate and widespread manner as other substances listed. Thus, prescription and over-the-counter medications have a more direct and common impact on job performance and safety.
