What This Study Found

Two adolescent patients presented with severe nausea and uncontrollable vomiting (hyperemesis) in the setting of chronic marijuana use. Both underwent extensive gastrointestinal workups that failed to identify any other cause.

In both cases, symptoms resolved when the patients stopped using marijuana. Both patients also displayed compulsive bathing behavior, a hallmark feature of cannabinoid hyperemesis syndrome (CHS) that had been consistently reported in adult cases.

These represented the first documented cases of CHS in pediatric patients, as the syndrome had previously been described only in adults.

Key Numbers

2 pediatric patients. Both had extensive GI workups with no identified cause. Both exhibited compulsive bathing. Both improved with cannabis cessation.

How They Did This

Case report of two pediatric patients presenting to the emergency department with severe cyclic vomiting and chronic marijuana use histories. Both received extensive gastrointestinal evaluations. Symptom resolution was documented after cannabis cessation.

Why This Research Matters

This report expanded recognition of cannabinoid hyperemesis syndrome to include adolescent patients, suggesting clinicians should consider CHS in younger patients with unexplained cyclic vomiting and marijuana use history.

The Bigger Picture

As cannabis use among adolescents increased, recognizing CHS in this age group became important for avoiding unnecessary testing and delayed diagnosis.

What This Study Doesn't Tell Us

Case reports cannot establish causation and represent only two patients. The mechanism of CHS remained poorly understood at the time.

Questions This Raises

  • ?How common is CHS among adolescent cannabis users?
  • ?Are there risk factors that make some young users more susceptible than others?

Frequently Asked Questions

What is cannabinoid hyperemesis syndrome?

CHS is a condition characterized by severe cyclic nausea and vomiting in people who use cannabis heavily over long periods. Symptoms typically resolve when cannabis use stops.

Why did these patients take compulsive baths?

Compulsive hot bathing is a distinctive feature of CHS. Patients report that hot showers or baths temporarily relieve their nausea, though the mechanism is not fully understood.
