Learn about substance use problems

Using drugs or alcohol in a way that harms you or that leads you to harm others, like your family or friends, is called substance use disorder. It can range from mild to severe. Moderate to severe substance use disorder is sometimes called addiction. This disorder can develop from the use of almost any type of substance. This includes alcohol, tobacco, marijuana, illegal drugs, prescription medicines, and over-the-counter medicines.
