Pills for Bites: The Alarming Link between Drug Abuse and Eating Disorders

The association between drug abuse and eating disorders (EDs) is not new. Since the 1970s, doctors have reported higher incidents of self-medication and drug abuse in a subset of eating disorder patients. Drugs, in this context, cover everything from laxatives and diet pills, to alcohol and street drugs.

Before discussing the parallels between food and drug rewards, we should first introduce some … Continue reading →
