As [cannabis use](https://cedclinic.com/cannabis-cardiovascular-health-insights-2024/) increases, clinicians need to recognize this paradoxical condition where cannabis—typically antiemetic—causes severe cyclic vomiting in heavy users. Clinical Summary CHS presents as cyclic episodes of severe nausea, vomiting, and abdominal pain in chronic, heavy cannabis users, often accompanied by compulsive hot bathing behavior that temporarily relieves symptoms. The syndrome likely results from prolonged exposure to high-potency THC causing dysregulation of the [endocannabinoid system](https://cedclinic.com/endocannabinoid-system-fear-extinction/), particularly in the hypothalamic-pituitary axis and gastrointestinal tract. Diagnosis requires high clinical suspicion since patients may not volunteer [cannabis use](https://cedclinic.com/cannabis-cardiovascular-health-insights-2024/) history, and the condition resolves only with complete cannabis cessation. Current research suggests increasing prevalence correlates with higher-potency products and daily use patterns. Dr. Caplan’s Take “I see patients spend months in diagnostic limbo with CHS because the idea that cannabis could cause vomiting seems counterintuitive. The hot shower sign is pathognomonic—when patients tell me they’re living in the bathroom running hot water for relief, CHS jumps to the top of my differential.” Clinical Perspective 🧠 Screen heavy cannabis users presenting with cyclic vomiting for compulsive bathing behavior and consider CHS early in the differential. Definitive diagnosis requires complete cannabis cessation—partial reduction won’t resolve symptoms. Educate patients that this is a recognized medical condition requiring complete abstinence, not dose reduction or product switching. 💬 Join the Conversation Have a question about how this applies to your situation?

Cannabinoid Hyperemesis Syndrome (CHS) is a condition characterized by severe nausea, vomiting, and abdominal pain in chronic cannabis users. It typically develops after prolonged, heavy use of cannabis products with high THC content. #### Who is at risk for developing CHS? Heavy, long-term cannabis users are at highest risk for developing CHS. The condition is most commonly seen in individuals who have used cannabis daily for months or years, particularly those using high-THC products. #### What are the main symptoms of CHS? The primary symptoms include cyclical episodes of severe nausea and vomiting, abdominal pain, and dehydration. Patients often experience relief from hot showers or baths, which is a characteristic feature of the condition. #### How is CHS diagnosed? CHS is diagnosed based on clinical symptoms, history of [chronic cannabis use](https://cedclinic.com/cannabis-tolerance-behavioral-models/), and ruling out other gastrointestinal conditions. The distinctive pattern of symptoms and temporary relief from hot water can help confirm the diagnosis. #### What is the treatment for CHS? The most effective treatment is complete cessation of cannabis use, which typically leads to resolution of symptoms. Supportive care includes IV fluids for dehydration and anti-nausea medications, though traditional antiemetics are often less effective in CHS cases.
