Patients with CHS experience cycles of intense nausea, abdominal pain, and vomiting that can last for hours or even days. Many require IV fluids or anti‑nausea medications, and some return to the ER multiple times before receiving a proper diagnosis.

The exact cause remains unclear, but researchers believe chronic exposure to certain compounds in cannabis may disrupt the body’s natural regulatory systems. Hot showers — oddly enough — provide temporary relief for many sufferers, a clue that has helped clinicians identify the condition.

As cannabis use becomes more widespread, awareness of CHS is increasingly important. Early recognition can prevent complications and reduce unnecessary medical testing. The most effective treatment remains simple: reducing or stopping cannabis use altogether.
