Alcohol Use Disorder (AUD)

For most adults, moderate alcohol use is probably not harmful. Your risk of developing an alcohol use disorder (AUD) depends on how much, how often, and how quickly you drink alcohol. Alcohol misuse means that drinking causes distress and harm. Over time alcohol misuse can increase your risk of AUD.
