If you have an alcohol use disorder, it means that you drink alcohol even though it's causing harm to yourself or others.
Alcohol use disorder can range from mild to severe. The more symptoms of this disorder you have, the more severe it may be. If you have it, you may find it hard to control your use of alcohol.
If you have this disorder, you may argue with others about how much you drink. Your schoolwork or job may be affected because of drinking. You may drink when it's dangerous or illegal, such as when you drive. Or you may engage in unsafe sex. This can lead to pregnancy and sexually transmitted infections. Your drinking may increase your risk of getting hurt or being in a car crash.
You also may have a strong need, or craving, to drink. You may feel like you must drink just to get by. It may get harder to say "no" to drinking. You may start to find alcohol more fun than anything else. Or you may want to stop drinking but can't. Your body may get used to alcohol. This is called physical dependence.
You may think that a drink or two is okay, even if it's illegal. Or you may think that it's okay if you only drink on the weekends. You may even think that binge drinking is okay. But teens who drink are more likely to develop alcohol use disorder than people who start drinking later in life.
Over time, drinking too much alcohol may cause health problems. These problems may include high blood pressure, liver problems, and problems with digestion.
