Cannabinoid Hyperemesis Syndrome in Adolescents: Diagnosis and Treatment Guide
The best current evidence for treating acute pediatric cannabinoid hyperemesis syndrome suggests IV rehydration followed by low-dose haloperidol, with complete cannabis cessation as the only long-term solution.
Quick Facts
What This Study Found
Current best evidence recommends IV rehydration and electrolyte correction, followed by haloperidol 0.05 mg/kg with or without a benzodiazepine for acute pediatric CHS. The only effective long-term treatment remains complete cessation of cannabinoid use.
Key Numbers
Haloperidol dose: 0.05 mg/kg IV; presenting features: cyclical nausea, emesis, abdominal pain, hot shower relief
How They Did This
Narrative review of current literature on adolescent CHS, covering diagnosis, pathophysiology, and treatment evidence.
Why This Research Matters
CHS prevalence in adolescents continues to grow as cannabis becomes more accessible and potent. Clinicians need practical guidance because high-quality treatment evidence specific to pediatric populations is lacking.
The Bigger Picture
As adolescent cannabis use patterns evolve toward higher-potency products and more frequent use, CHS is likely to become an increasingly common pediatric emergency presentation.
What This Study Doesn't Tell Us
High-quality treatment evidence for adolescent CHS remains lacking. Recommendations are based on limited data extrapolated partly from adult studies.
Questions This Raises
- ?Are there pharmacological treatments that could prevent CHS relapse in adolescents who cannot achieve cessation?
- ?Does the potency of cannabis products influence CHS severity in young people?

What do these levels mean? →Frequently Asked Questions
How is cannabinoid hyperemesis syndrome treated in adolescents?
Current best evidence suggests IV rehydration, electrolyte correction, and haloperidol 0.05 mg/kg with or without a benzodiazepine. Complete cessation of cannabis use is the only known long-term treatment.
How do you diagnose CHS in teenagers?
The key features are cyclical nausea, vomiting, and abdominal pain in the context of chronic cannabis use, with symptom relief from hot showers being a characteristic finding.
