Recent investigations of caffeine abuse have questioned the indiscriminant use of this commonly accepted drug. In some individuals, chronic excessive caffeine consumption leads to the development of caffeinism, a syndrome which includes increased anxiety, depression, frequency of psychophysiological disorders, and possibly degraded performance. This paper reviews research demonstrating the abuse potential of caffeine. Special attention has been given those factors which mediate the wide individual differences in consumption patterns, susceptibility to abuse, and the varied psychological and physiological responses to this drug. While the development of caffeine abuse is probably best viewed as an idiosyncratic process, general guidelines for the recognition of potential abuse, and caffeinism proper, are offered.

Suicide is considered a deliberate act initiated and concluded by a person with full knowledge or expectation of a fatal result, and one of the main symptoms of depression. An individual's conscious and excessive ingestion of a damaging substance is also considered to be an attempted suicide. Despite limited knowledge of caffeine abuse, deaths from overdose of caffeine have been reported in the literature. Thus, this study aims to review the existing literature on caffeine consumption and suicide attempts and deaths, investigating the relation between caffeine consumption and suicide attempts and deaths. We found 24 studies that discuss the relationship between caffeine and suicide. The findings revealed that, despite being an addictive substance and potentially fatal in higher doses, caffeine was still a rare factor in a number of studies concerning its relation with suicide attempts and death. The majority of the research found in this study was of the case study type. Furthermore, the majority of studies focus on the assistance offered to the victim and the procedures undertaken to control the bodily damage created. The existing studies indicate the substance may act as either a direct or an indirect agent in suicide. Therefore, a better understanding of how caffeine may be linked to suicide is crucial for its prevention.
