WHY IT MATTERS: If you use cannabis daily and experience recurring episodes of severe vomiting that hot showers seem to relieve, you should discuss cannabinoid hyperemesis syndrome with your physician before your next emergency room visit. CLINICAL OVERVIEW: Cannabinoid hyperemesis syndrome is a paradoxical condition in which heavy, long-term cannabis use causes cyclical episodes of severe nausea, vomiting, and abdominal pain, often relieved temporarily by hot showers or baths. The syndrome is thought to involve dysregulation of cannabinoid receptors in the gut and hypothalamus, particularly with chronic high-potency THC exposure, though the precise mechanism remains under active investigation.
Cannabis hyperemesis syndrome is on the rise: What symptoms to watch for – The Hill
WHY IT MATTERS: If you use cannabis daily and experience recurring vomiting that improves with hot showers, you may have cannabis hyperemesis syndrome, and stopping cannabis use is currently the only reliable cure. CLINICAL OVERVIEW: Cannabis hyperemesis syndrome (CHS) is a paradoxical condition in which chronic, heavy cannabis users develop cyclic episodes of severe nausea, vomiting, and abdominal pain, often relieved temporarily by hot showers or baths. The syndrome is frequently misdiagnosed for months or years because patients and clinicians alike associate cannabis with antiemetic properties, creating a counterintuitive diagnostic barrier.
