Abstract
Kratom is a plant extract readily available for purchase in the USA. It is known to produce both stimulant and opioid-related effects, predisposing it to abuse. The long-term effects of kratom are poorly understood. In rare cases, serious side effects have been reported. Here, we report a case of a patient with a history of bipolar type schizoaffective disorder presenting with acute onset paranoia and delusions. The patient had been hospitalized seven times previously with psychotic symptoms, with no reported history of paranoid delusional thought content in previous admissions. It was discovered that the patient had been ingesting increasingly large quantities of kratom in the weeks leading up to the admission. It is believed that kratom may be responsible for the novel symptoms contributing to the patient's acute psychiatric decompensation.
