Caffeine-induced psychosis

Caffeine-induced psychosis is a relatively rare phenomenon that can occur in otherwise healthy people. Overuse of caffeine may also worsen psychosis in people suffering from schizophrenia.[1] It is characterized by psychotic symptoms such as delusions, paranoia, and hallucinations.[2][3] This can happen with ingestion of high doses of caffeine, or when caffeine is chronically abused, but the actual evidence is currently limited.[1][4][5]
