RESUMO
INTRODUCTION: In the western world, cannabis is the most widely used drug of abuse. Cannabinoid hyperemesis syndrome, which seems to be a rare paradoxical reaction in individuals with a particular predisposition, is characterized by cyclic severe nausea and vomiting in long-term cannabis users. While the symptoms are unresponsive to antiemetic drugs, compulsive hot baths result in a considerable symptom relief. METHODS: We report the first case of cannabinoid hyperemesis syndrome in pregnancy. A 26-year-old patient was admitted to our clinic in the 10th week of gestation. CONCLUSION: Before undertaking time-consuming and expensive medical examinations to rule out other medical reasons for therapy-resistant hyperemesis in pregnancy, obstetricians should determine whether compulsive bathing or showering provides symptomatic relief and ask specific questions regarding possible/suspected cannabis consumption.
