Educational Pearls

• Cannabinoid Hyperemesis syndrome is a relatively new diagnosis that presents with vomiting and abdominal pain without a clear etiology in the setting of daily marijuana use.
• The pathophysiology is not well-understood well, but may involve cannabinoid receptors in the gut.
• Treatment is abstinence from marijuana, fluids, dextrose, and antiemetics (haldol, ondansetron, etc). Opioids should be avoided.
• Capsaicin cream on the abdomen may be helpful, as it can distract from the pain and vomiting. Milk can be used to reverse its effects.
