Addiction is a chronic brain dysfunction that involves the reward, motivation, and memory parts of the brain. It refers to the way that your body craves a substance regardless of negative consequences. Those with a substance use disorder can have trouble understanding how their behavior may cause problems, and they will likely be unable to stay away from the substance. In the United States, about 21 million Americans have an addiction, according to the Association of American Medical Colleges. At Enlight Treatment Center, we understand how difficult healing from a substance use disorder can be, and we are here to help.
