Why Addictive Behavior Often Starts in Adolescence

Recognizing why addictive behavior in adolescence occurs is the first step toward effective intervention. By understanding brain development, families can move from frustration to clinical support.


You’re not the only one who has ever looked at a teenager and wondered why they don’t seem to have any “brakes” when it comes to dangerous things. We talk about this a lot at Casa Leona Recovery Center. According to science, the human brain doesn’t finish building itself until a person is in their mid-twenties. The part of the brain that looks for excitement is working hard throughout those teen years, but the part that controls impulses—the prefrontal cortex—is still waiting for the parts to come.

The “Engine vs. Brakes” Biology

It feels like having a huge engine in your car but brakes like a tricycle. This biological divide is why people typically start to act in ways that are addictive when they are teenagers. Teenagers’ brains are literally wired to prefer short-term benefits over long-term effects. In the calm and loving environment of Leona Valley, we help families understand that this isn’t just “rebellion”; it’s a fragile time for brain development.

Vulnerable Windows for Brain Development

If a young person uses drugs or alcohol at this time, it can “lock in” specific pathways before the brain has a chance to grow up. Clinical research shared by the American Academy of Child & Adolescent Psychiatry explains that addictive behavior in adolescence is heavily influenced by this developmental gap. We offer high-quality residential care at Casa Leona Recovery Center that is appropriate for this time of life.
