The human brain is the most complex organ in the body—you need it to drive a car, to enjoy a meal, to breathe, to create an artistic masterpiece, and to enjoy everyday activities. In brief, the brain regulates your body’s basic functions; enables you to interpret and respond to everything you experience; and shapes your thoughts, emotions, and behavior. Drugs, however, can alter important brain areas that are necessary for life-sustaining functions and can drive the compulsive drug abuse that marks addiction. As a result, NIDA supports a large body of neuroscience research that can provide clues how better to manage and prevent substance use disorders.
