Caffeine: A Survey of Some of the Known and Suspected Deleterious Effects of Habitual Use

Abstract
Summary: The potential untoward consequences of habitual caffeine use are considered in terms of two broad classes of deleterious effects: (a) the symptom constellation known as‘caffeinism', and (b) a number of disease states in which caffeine may be an etiological factor. In addition, a brief overview is provided of recent attempts to assist heavy users to reduce caffeine intake to moderate and presumably safer levels.
