A Clinician's Guide to Diagnosing and Treating Cannabinoid Hyperemesis Syndrome
CHS is under-diagnosed, presents with cyclic vomiting and compulsive hot shower use, and often fails to respond to standard anti-nausea medications.
Quick Facts
What This Study Found
CHS is characterized by cyclic, severe vomiting, compulsive hot showering, and chronic cannabis use history. Standard antiemetics may not fully work. Abstinence remains the most effective long-term approach.
Key Numbers
Ondansetron may not fully attenuate symptoms. Abstinence is most effective prevention.
How They Did This
Clinical review article aimed at helping clinicians identify and treat CHS.
Why This Research Matters
CHS is under-recognized, leading to repeated unnecessary ER visits and testing. Better recognition could reduce costs and patient suffering.
The Bigger Picture
As cannabis use shifts toward higher potency and frequency, CHS will likely become increasingly common.
What This Study Doesn't Tell Us
Narrative review. CHS pathophysiology incompletely understood. Treatment evidence from case reports mostly.
Questions This Raises
- ?What minimum cannabis exposure triggers CHS?
- ?Are some individuals genetically predisposed?
