Title: A Case of Kratom-Induced Mood Disorder

Abstract

Kratom, a plant extract from a tropical tree indigenous to Southeast Asia, has gained popularity in several countries due to its stimulant and opioid-like effects in low and high doses, respectively. It is marketed as a natural remedy for chronic pain, anxiety, depression, and opioid dependence; however, it carries risks such as dependence, withdrawal, and potential psychiatric complications such as mood or psychotic symptoms. This session will explore one such case in which products with active agents of Kratom, namely mitragynine and 7-hydroxymitragynine, induced a mood disorder that led to a first psychiatric hospitalization in a 66 year old male.
