Drug addiction is a major problem in many countries in the world. it is a condition where a person takes a drug compulsively, despite potential harm to themselves, or their desire to stop. Although being addicted implies dependence, it is possible to be dependent on a drug without being addicted. People that take drugs to treat diseases and disorders, which interfere with their ability to function, may experience improvement of their condition.

Recovering from an addiction is a modification of an addicts behavior and habits, physical withdrawal, and mental and social relationship repair. It is important to take a drug treatment to help make recovery attainable and sustainable. 

Many individuals with drug addictions, particularly to stimulants like cocaine and methamphetamine, often have associated eating disorders such as anorexia nervosa, bulimia nervosa or binge eating. Because their drug of choice artificially suppresses their appetite, these food disorders often lie dormant and even the affected individuals may not know they have an eating disorder.

As soon as an individual begins drug rehab and abstains from using their drug(s) of choice, hidden eating disorders can suddenly appear.
