What are some indicators of substance abuse in juveniles?

The correct answer highlights that changes in behavior and withdrawal from activities are significant indicators of substance abuse in juveniles. When a young person begins to misuse substances, it often leads to noticeable shifts in their behavior. This can manifest as increased isolation from friends and family, loss of interest in previously enjoyed hobbies, or a general decline in social engagement. Such changes can stem from the physical and psychological effects of substances, as well as the perceived need to hide their use from others.

In contrast, increased participation in sports typically suggests a positive engagement with healthy activities, which doesn't correlate with substance abuse. Likewise, improvement in academic performance would generally indicate a level of focus and stability inconsistent with substance misuse. Consistent interaction with peers is also typically a sign of healthy socialization. In the context of substance abuse, a juvenile is more likely to withdraw from peer interactions that may lead to accountability or expose their behavior.
