What is a Substance Use Disorder?
A substance use disorder (SUD) occurs when the use of alcohol or drugs leads to significant problems in a person’s health, daily life, or responsibilities at work, school, or home. When someone has a SUD, their brain and behavior are impacted, making it difficult for them to control their consumption of alcohol or drugs.
SUDs can affect individuals of all ages and backgrounds. They are common, often recurring, and can be serious. However, they are treatable, and recovery is possible.
