Which of the following is a consequence of alcohol and drug use among teens?

The relationship between alcohol and drug use among teens and the increased risk of injury is well-documented. Substance use can impair judgment, coordination, and overall cognitive function, leading to a higher likelihood of accidents and injuries. For example, intoxication can result in reckless behavior such as driving under the influence, engaging in dangerous physical activities, or getting involved in violent situations. Additionally, substance use can diminish a teen's ability to assess risks accurately, further contributing to the vulnerability of injuries.

In contrast, other options such as improved academic performance, stronger family relationships, and improved mental health do not align with the established effects of substance use. Typically, alcohol and drug use is linked to lower academic achievement, strained family dynamics, and exacerbated mental health issues, illustrating the contrast in consequences effectively.
