What is a Substance Use Disorder?
A substance use disorder (SUD) occurs when alcohol or drug use creates serious issues in a person’s health, daily life, or responsibilities at work, school, or home. When a person has a SUD, their brain and behavior are affected, making it difficult for them to control their intake of alcohol or drugs.
SUDs affect people of all ages and walks of life. They are common, recurrent, and often serious. However, they are treatable, and recovery is possible.
