Screaming, vomiting, and daily weed: The rise of ‘scromiting’ among chronic cannabis users

High-quality evidence with meaningful patient or clinical significance.
Cannabinoid hyperemesis syndrome represents a clinically significant paradoxical adverse effect of chronic cannabis use that may be underrecognized in emergency departments, potentially leading to unnecessary diagnostic workups and delayed symptom resolution. Recognition of this condition’s pathognomonic presentation (severe cyclic vomiting with compulsive hot shower use in chronic cannabis users) enables prompt diagnosis and appropriate management through cannabis cessation rather than continued investigation. As cannabis legalization increases population exposure, clinicians should maintain heightened awareness of this syndrome to improve patient outcomes and reduce healthcare resource utilization.
Cannabinoid hyperemesis syndrome (CHS) is an increasingly recognized paradoxical condition characterized by cyclical episodes of severe nausea, vomiting, and abdominal pain in patients with chronic heavy cannabis use, particularly those using high-potency THC products. The pathophysiology is incompletely understood but appears to involve dysregulation of cannabinoid receptors in the gastrointestinal tract and hypothalamus following prolonged THC exposure. A distinctive clinical feature is the temporary relief of symptoms with hot showers or baths, which can paradoxically mask the underlying diagnosis and delay appropriate treatment. Patients with CHS frequently present to emergency departments with acute gastrointestinal distress, making recognition of this syndrome clinically important to avoid unnecessary diagnostic workup and to guide appropriate management. Physicians should maintain suspicion for CHS in daily cannabis users presenting with recurrent severe vomiting, particularly when conventional antiemetics prove ineffective and hot water exposure provides relief. Counseling patients about CHS risk and discussing cannabis cessation as the definitive treatment may help prevent repeated emergency visits and improve outcomes.

The compulsive hot shower-taking is almost diagnostic, and the condition resolves with cannabis cessation, but patients often resist this intervention because they’ve been using cannabis therapeutically for other symptoms, which creates a genuine clinical dilemma that requires honest conversation about dose, duration, and product type.”
? Cannabinoid hyperemesis syndrome (CHS) represents a paradoxical and increasingly recognized adverse effect of chronic, high-dose cannabis use, characterized by cyclical episodes of severe nausea and vomiting that counterintuitively improve with hot water exposure. While the exact pathophysiological mechanism remains incompletely understood, the condition appears to involve dysregulation of cannabinoid receptors in the gastrointestinal tract and central nervous system, and distinguishing CHS from other causes of recurrent vomiting requires careful history-taking around cannabis use patterns, symptom timing, and response to heat. Important caveats include the lack of specific biomarkers for diagnosis, significant variation in individual susceptibility despite similar exposure patterns, and the possibility of concurrent gastrointestinal or metabolic conditions that may confound the clinical picture. Given the rising prevalence of high-potency cannabis products and increased normalization of
