What is a concern that could arise from rumors about substance use among students?

Decreased academic performance is a significant concern that could arise from rumors about substance use among students because such rumors can create a toxic educational environment. When rumors circulate regarding substance abuse, it can lead to increased anxiety, stress, and distraction among students. Students may become preoccupied with the social implications of these rumors, which can interfere with their ability to focus on their studies and engage fully in academic activities.

Additionally, if the rumors result in social stigma or peer pressure, students may be more likely to engage in risky behaviors themselves, further impacting their academic performance. The cumulative effect of distraction, stress, and possible substance use can lead to lower grades, absenteeism, and decreased motivation, ultimately contributing to a decline in overall academic achievement.

In contrast, the other options suggest outcomes that are generally positive or constructive, which would not typically be associated with the negative consequences stemming from rumors about substance use.
