‘‘Addiction’’ is defined in the dictionary as: (1) a functional
abnormality of the body caused by food or pharmaceutical toxins;
(2) a pathologic condition that one cannot tolerate without the
continuous administration of alcohol or drugs; and (3) the status of
not being able to rationally judge or distinguish due to certain
ideas or objects. ‘‘Addiction,’’ however, commonly handled by
neuropsychiatric departments, is a phenomenon that manifests
tolerance, withdrawal symptoms, and dependence, accompanied
by social problems [8,9]. The term was once limited to drugs or
substances, but it is now also applied to gambling, Internet,
gaming, mobile-phone usage, and other behavioral addictions
[10].
