Which of the following is a potential effect of substance abuse on a soldier's performance?

Substance abuse can significantly impair a soldier's performance, primarily by increasing the risk of accidents and errors. When individuals abuse substances, their cognitive functions, reflexes, and judgment are often compromised. This can lead to poor decision-making, reduced attention to detail, and slower reaction times, all of which are critical in military settings.

The presence of substances in the system can create a false sense of confidence, leading soldiers to underestimate potential dangers or overlook critical safety protocols. This can result in a higher likelihood of accidents, not only affecting the individual but also endangering fellow soldiers and the mission at hand.

While one might think that substance abuse could somehow improve certain areas, such as decision-making or leadership skills, this is a misconception. In fact, the reality is that substance abuse detracts from these abilities, leading to a decline in overall performance and effectiveness as a soldier.
