Chemicals Help Make Us What We Are

Abstract

Notice that it is the chemicals inside your brain that help make you feel and act the way you do. All of the substances of abuse (that term is used to include both alcohol and all other drugs used deliberately to cause a “high”) are chemicals that get into your body, find their way to your brain, and, as the result of a variety of different mechanisms, change how you feel. These drugs almost always interact, and interfere, with normal body chemicals. So, in order to understand what drugs of abuse do to you and to your chemical makeup, you must know something about how the brain works.
