Dependence on Caffeine
Caffeine dependence can occur in some users but by definition it is not a true addiction, though many people may feel addicted to it and consistently fail in their efforts to stop or control their intake.

Not all health care organizations agree on capacity for caffeine dependence, a point well-illustrated in the American Psychiatric Association’s (APA) Diagnostic and Statistical Manual of Mental Disorders. This manual omits listing substance dependence on caffeine as a potential diagnosis.
The World Health Organization, on the other hand, includes caffeine dependence in its Classification of Mental and Behavioral Disorders (ICD-10).
