Substance addiction is a complex disorder characterized by compulsive drug use. While addiction is difficult to understand, all abused substances share one thing in common - repeated use could change the way the brain looks and functions. Some people can use recreational or prescription drugs without ever experiencing negative consequences or addiction. For others, substance use can cause problems at school, work and home, and in relationships.
