Clinical diagnosis, management, and cessation guidance for clinicians. --- ✦ New CED Clinical Relevance #67 Notable Clinical Interest Emerging findings or policy developments worth monitoring closely. ResearchSafetyTHCMental HealthNeurologyPolicyDosing Why This Matters Clinicians need to recognize [Cannabinoid Hyperemesis](https://cedclinic.com/cannabis-hyperemesis-syndrome-virginia-er-cases-surge/) Syndrome (CHS) as a diagnosis in frequent cannabis users presenting with unexplained recurrent nausea and vomiting, since the condition requires cessation of use rather than standard antiemetic treatments. Understanding CHS prevalence and presentation helps prevent unnecessary gastroenterology workups and surgical interventions in patients whose symptoms will resolve only with cannabis discontinuation. Patients using cannabis chronically should be counseled about this potential adverse effect during substance use screening and medical history. Clinical Summary [Cannabinoid hyperemesis](https://cedclinic.com/cannabis-hyperemesis-syndrome-virginia-er-cases-surge/) syndrome (CHS) is an increasingly recognized condition affecting chronic, heavy cannabis users who present with cyclic nausea, vomiting, and abdominal pain that paradoxically improves with hot showers. As [cannabis legalization](https://cedclinic.com/the-forgotten-history-of-hemp-in-america/) expands and use patterns shift toward higher potency products and increased frequency, clinicians should maintain awareness of CHS as a differential diagnosis in patients with unexplained chronic gastrointestinal symptoms, particularly those who deny or minimize cannabis consumption. The syndrome appears linked to dysregulation of [cannabinoid receptors](https://cedclinic.com/citral-cannabinoid-receptor-2-activation-pain-relief/) in the gastrointestinal tract and central nervous system, though the precise mechanism remains incompletely understood. Recognition of CHS is critical because patients often undergo extensive gastrointestinal workup and may receive ineffective treatments before the correct diagnosis is established, while the definitive management remains cannabis cessation. Clinicians should screen for [cannabis use](https://cedclinic.com/cannabis-cardiovascular-health-insights-2024/) patterns and consider CHS in patients with recurrent nausea and vomiting refractory to standard antiemetic therapy, as early recognition and patient counseling on cessation can prevent unnecessary procedures and hospitalizations. Dr. Caplan’s Take “Cannabinoid Hyperemesis Syndrome is a real clinical entity we’re seeing more frequently in our practice as [cannabis use](https://cedclinic.com/cannabis-cardiovascular-health-insights-2024/) becomes more normalized, but we still have significant gaps in our understanding of its pathophysiology and why it affects some heavy users and not others. The pattern is consistent enough that we screen for it in chronic users presenting with recurrent nausea and vomiting, though larger prospective studies would help us better predict who’s at risk and develop more targeted management strategies beyond simply advising abstinence.” Clinical Perspective 💊 [Cannabinoid Hyperemesis](https://cedclinic.com/cannabis-hyperemesis-syndrome-virginia-er-cases-surge/) Syndrome (CHS) represents an increasingly recognized but still underdiagnosed condition among regular cannabis users, characterized by cyclic nausea, vomiting, and abdominal pain that paradoxically improves with hot showers and cessation of use. Clinicians should maintain suspicion for CHS in patients presenting with recurrent nausea and vomiting, particularly those with frequent or long-term [cannabis use](https://cedclinic.com/cannabis-cardiovascular-health-insights-2024/), since the condition can be mistaken for other gastrointestinal disorders and may lead to unnecessary investigations and treatments. Important confounders include variable cannabis potency and frequency of use across individuals, the role of different [cannabinoid profiles](https://cedclinic.com/cannabis-clinical-trials-mental-health-march-2026/), and the possibility that some patients with underlying gastrointestinal conditions may have concurrent cannabis use rather than CHS as the primary etiology.
