title: Cannabinoid Hyperemesis Syndrome During Pregnancy: A Case Report.
abstract: BACKGROUND
  Cannabinoid hyperemesis syndrome (CHS) is a syndrome characterized by chronic marijuana use, cyclic vomiting, and compulsive bathing. Given the similarities this syndrome shares with hyperemesis gravidarum, it is likely that this is a highly underdiagnosed syndrome. We present a case of severe nausea and vomiting during pregnancy that met the criteria for CHS.
  
  
  METHODS
  This case outlines the course of recurrent nausea and vomiting due to cannabinoid hyperemesis in a pregnant patient and illustrates the similarities between hyperemesis gravidarum and CHS and the value of obtaining a complete history that includes the use of marijuana.
  
  
  CONCLUSIONS
  Recognition of this syndrome will aid in patient care, lessen the economic burden of an extensive workup, and hopefully lessen provider frustration with diagnosis and treatment of a common and underdiagnosed entity.
