All kinds of American women abuse drugs and alcohol. They may be rich or poor, young or old, urban or rural, professional or homemaker.

Although addiction begins with drug abuse, it doesn't mean just using a lot of drugs.

At some point, changes occur in the brain that can turn drug abuse into addiction.Learn more about addictions ›
