Open article record in new tab ↗Cannabinoid hyperemesis syndrome (CHS) is a rare but increasingly recognized condition among chronic cannabis users, characterized by cyclic nausea, vomiting, and relief with hot bathing. During pregnancy, CHS may mimic hyperemesis gravidarum (HG), complicating diagnosis and management. We report the case of a 24‐year‐old pregnant patient who presented at 20 weeks′ gestation with recurrent nausea, vomiting, and la…
Objective This study aimed to evaluate the accuracy, completeness, and clinical usefulness of YouTube (Alphabet Inc., Mountain View, CA) videos about cannabinoid hyperemesis syndrome (CHS). Methods This cross-sectional study assessed YouTube videos that were identified using standardized CHS-related search terms and predefined eligibility criteria. Trained reviewers used an author-developed CHS content checklist a…
Open article record in new tab ↗INTRODUCTION: Cannabinoid hyperemesis syndrome (CHS) is a debilitating disorder of chronic, heavy cannabis users characterized by cyclic severe nausea, vomiting, and abdominal pain that is classically relieved by hot baths. Standard antiemetics often fail, and dysregulation of endocannabinoid signaling with involvement of heat-sensitive TRPV1 channels has been proposed. Topical capsaicin - a TRPV1 agonist - has be…
Open article record in new tab ↗ObjectiveAbdominal pain is one of the most common emergency department (ED) complaints, with many patients experiencing recurrent episodes due to cannabinoid hyperemesis syndrome (CHS), a syndrome characterized by pain and vomiting in the setting of chronic cannabis use. This pilot study aimed to demonstrate the ability to enroll patients with CHS, characterize patient-reported outcomes (PROs), and estimate 30-day…
Background: Cannabinoid hyperemesis syndrome (CHS) is a condition characterized by cyclic abdominal pain, vomiting, and nausea, primarily affecting adolescents and adults with a history of chronic cannabis use. The diagnosis of CHS is clinical, with symptom resolution upon cannabis cessation considered pathognomonic. The overlap of CHS symptoms with other conditions complicates the differential diagnosis, particul…
Cannabinoid hyperemesis syndrome (CHS) is a paradoxical condition seen in chronic cannabis users, marked by recurrent nausea, vomiting, and abdominal discomfort. Although more widely recognized in emergency medicine, CHS remains underdiagnosed in the perioperative setting, where its symptoms may be misattributed to common postoperative phenomena such as anesthetic effects, opioid-induced nausea, or surgical compli…
Cannabinoid hyperemesis syndrome (CHS) is characterized by a pattern of cyclic vomiting and abdominal pain despite an absence of an organic cause, occurring in regular cannabis users. This syndrome was first described in 2004. Initially considered rare, with the increased use and legalization of cannabis, a growing incidence of diagnoses has been observed. Data on the pediatric population are still scant despite t…
Open article record in new tab ↗Cannabinoid hyperemesis syndrome (CHS) is a condition in which users of marijuana experience symptoms of nausea and vomiting. Due to the nature of the condition, patients may ultimately be admitted to the hospital for complications such as weakness and fluid loss. The usual treatment options for nausea and vomiting include fluids and a combination of metoclopramide, ondansetron, promethazine, or prochlorperazine.…
Open article record in new tab ↗Cannabinoid hyperemesis syndrome (CHS) is an emerging disorder in chronic cannabis users, characterized by recurrent nausea, vomiting, severe abdominal pain, and compulsive hot bathing. We report a case of CHS complicated by profound lactic acidosis (lactate 6.1 mmol/L), highlighting this metabolic derangement as a secondary effect of severe dehydration and physiological stress from intractable vomiting and pain.…
Open article record in new tab ↗This review focuses on Cannabis Hyperemesis Syndrome (CHS) in youth, a condition linked to chronic cannabis use and characterized by cyclic vomiting, abdominal pain, and dehydration. The objectives were to explore CHS progression in youth and its impact on health, and to assess current treatment strategies. There are the three distinct phases of CHS: prodromal, hyperemetic, and recovery. During the prodromal phase…
Open article record in new tab ↗Importance Cannabinoid hyperemesis syndrome (CHS), ie, recurrent emesis from chronic cannabis use, is increasingly observed in emergency departments (EDs), yet population-level estimates and sociodemographic correlates remain underexplored. Objective To estimate CHS prevalence in US EDs, assess trends from 2016 to 2022, and examine sociodemographic associations. Design, setting, and participants This cross-section…

Open article record in new tab ↗Cannabinoid hyperemesis syndrome presents as a complex of symptoms and signs encompassing nausea, vomiting, abdominal pain, and hot water bathing behavior, most typically in a heavy cannabis user. Its presentation is frequently associated with hypothalamic-pituitary-adrenal axis activation with stress and weight loss. Recent investigation has identified five statistically significant mutations in patients distinct…
Open article record in new tab ↗Cannabis-related emergency department visits have increased after legalization of cannabis for medical and recreational use. Accordingly, the incidence of emergency department visits due to cannabinoid hyperemesis syndrome in patients with chronic cannabis use has also increased. The aim of this study was to examine trends of emergency department visit due to cannabinoid hyperemesis syndrome in Nevada and evaluate…
Open article record in new tab ↗The increasing prevalence of cannabis worldwide requires awareness of a potential, less recognized, paradoxical entity, the cannabinoid hyperemesis syndrome (CHS). This includes cyclic episodes of nausea, vomiting, and compulsive hot water bathing for alleviation in individuals with chronic cannabis use. An 18-year-old male with daily and prolonged cannabis use has excessive nausea and vomiting, is diagnosed with…
