If you answered “yes” to any of the questions above, it is imperative that you continue with
this chapter. We are going to look at substance use and abuse as it pertains to eating disor-
ders. Although substance abuse most often refers to alcohol and illicit drug use, substance
abuse also refers to the use of prescription and over-the-counter medications for weight
control. We are going to discuss the use of alcohol, illicit drugs, and other prescription and
non-prescription medications that may play a critical role in the development of an eating
disorder. Even if you believe you do not have a problem with substance use and/or abuse,
we still encourage you to read this chapter.
