A nursing guide to recognizing and managing cannabinoid hyperemesis syndrome in the emergency department
CHS presents with recurrent vomiting, abdominal pain, and resistance to standard antiemetics in chronic marijuana users, with abstinence being the most effective treatment.
Quick Facts
What This Study Found
This review for emergency nursing practitioners outlined the key features of CHS. Standard antiemetic treatments are ineffective, and narcotics given for abdominal pain may cause worsening rebound pain. The only reliably effective treatment is abstinence from marijuana.
The review referenced a 2004 Australian study that identified 19 chronic marijuana users presenting to an emergency department with recurrent vomiting and abdominal pain as the foundational description of the syndrome. The author predicted that marijuana legalization would increase the number of long-term users and consequently the number of CHS cases.
The review emphasized that advanced practice nurses need to include CHS in their differential diagnosis for patients presenting with recurrent nausea, vomiting, and abdominal pain.
Key Numbers
Referenced 2004 study identified 19 chronic users with CHS. Standard antiemetics described as ineffective. Narcotics may cause rebound pain. Abstinence identified as the best treatment.
How They Did This
Narrative review and clinical guide for advanced practice nurses working in emergency settings, covering recognition, differential diagnosis, and management of CHS.
Why This Research Matters
Emergency nurses are often the first clinicians to evaluate patients with CHS. Recognition of the syndrome can prevent unnecessary testing, inappropriate treatment (which may worsen symptoms), and repeated emergency visits.
The Bigger Picture
As cannabis legalization expands the population of chronic users, CHS cases in emergency departments are expected to rise. Clinical education across disciplines, including nursing, is essential for timely recognition and appropriate management.
What This Study Doesn't Tell Us
Narrative review for clinical practice rather than systematic research review. Based on limited published literature available at the time. Does not address the mechanism of CHS or predict individual risk.
Questions This Raises
- ?What is the best acute treatment for CHS in the ED besides abstinence?
- ?How should nurses approach the conversation about marijuana cessation with CHS patients?
- ?Could screening tools be developed for early CHS identification?

What do these levels mean? →Frequently Asked Questions
Why don't anti-nausea medications work for CHS?
Standard antiemetics target different nausea pathways than those involved in CHS. The mechanism of CHS-related vomiting involves cannabinoid receptor dysregulation that does not respond to conventional treatments.
What should emergency nurses know about CHS?
CHS should be considered in any chronic marijuana user with recurrent vomiting and abdominal pain. Standard treatments are ineffective, narcotics may worsen symptoms, and marijuana cessation is the definitive treatment.
