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

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.
