Addiction usually begins in adolescence, thus early prevention is critical.
This image illustrates the age at which drug dependence is first diagnosed, which for tobacco, alcohol and marijuana, is typically in adolescence or early adulthood. Much of the research supported by NIDA is aimed at preventing drug use from ever starting. This research ranges from highly complex molecular and imaging studies to devising effective messages that “speak” to young people.
As a result of scientific research, we know that addiction is a disease that affects both brain and behavior.
