Scromiting is the internet’s name for one of the strangest, most painful things emergency doctors see: a person vomiting so violently that they scream through it. The word is a mashup of “screaming” and “vomiting,” and it’s tied to a real, documented medical condition called cannabinoid hyperemesis syndrome, or CHS.
If you’ve come across the term on social media and wondered whether it’s just a meme, it isn’t. Emergency departments across the U.S. have reported a sharp rise in cases tied to heavy, long-term cannabis use, and the pattern is well established in clinical literature going back to 2004.
What Does Scromiting Mean?
Scromiting describes the hyperemetic phase of CHS: cycles of intense nausea, repeated vomiting (sometimes up to five times an hour), and abdominal pain severe enough that patients cry out or scream during episodes. According to the Cleveland Clinic, some people use the term specifically to describe this combination of screaming and vomiting brought on by the intensity of the pain.
It’s not a formal diagnosis. You won’t find “scromiting” in a medical chart. What you’ll find instead is CHS, first identified by Australian researchers in 2004 after a cluster of chronic cannabis users showed up with unexplained cyclic vomiting.
The Medical Condition Behind the Slang: CHS
Cannabinoid hyperemesis syndrome happens in people who use cannabis frequently, usually weekly or more, over a long stretch of time, often a decade or more. It’s linked to THC, the psychoactive compound in marijuana, and the leading theory is that prolonged, heavy exposure overwhelms the body’s endocannabinoid system, disrupting the normal signals that control nausea and vomiting.
That’s the paradox at the center of CHS. Cannabis is widely used, including in clinical settings, to ease nausea. In a smaller group of long-term users, the same substance appears to flip that effect on its head.
CHS typically unfolds in three stages:
- Prodromal phase. Morning nausea, mild stomach discomfort, and a growing fear of vomiting. This can drag on for months or years, and many people keep using cannabis during this stage because it seems to help.
- Hyperemetic phase. This is the scromiting phase: sudden, severe vomiting, retching, and pain that can send someone straight to the ER.
- Recovery phase. Symptoms fade over days to weeks once cannabis use stops completely, only to return if use starts again.
The Hot Shower Connection
One of the odder hallmarks of CHS is compulsive hot bathing. People in the hyperemetic phase often report that scalding showers or baths, sometimes for hours at a stretch, briefly ease their symptoms. Doctors aren’t entirely sure why. One theory: extreme heat may distract the body’s pain receptors from the nausea signal.
It’s not a treatment. Spending hours under hot water can lead to dehydration and, in some documented cases, burns.
Who’s at Risk
Not every cannabis user develops CHS, and researchers still can’t fully explain why some heavy users get it and others never do. The clearest risk factors identified so far:
- Weekly or more frequent cannabis use
- Years of consistent use, often starting in the teens
- Use of high-potency products, including concentrates and vapes
- A history of starting cannabis use at a young age
Modern cannabis products carry far more THC than they did a generation ago. Flower that once tested around 2 to 3 percent THC now commonly reaches 15 to 30 percent, and vape and edible products can push potency even higher. Several recent reports point to rising CHS cases specifically among teens and young adults as potency has climbed.
Symptoms to Watch For
Beyond the screaming-vomiting pattern itself, CHS commonly involves:
- Persistent or recurring nausea, often worse in the morning
- Repeated vomiting that returns in cycles
- Sharp or cramping abdominal pain
- Loss of appetite and weight loss over time
- Compulsive hot showers or baths for relief
Left untreated, repeated episodes can lead to dehydration, electrolyte imbalances, and in rare cases, kidney injury or damage to the esophagus from forceful vomiting.
Treatment: What Actually Works
There’s no FDA-approved medication specifically for CHS, and standard anti-nausea drugs often don’t touch it. In the emergency room, treatment usually focuses on managing the crisis: IV fluids for dehydration, electrolyte correction, and sometimes topical capsaicin cream, which some patients find helps ease the pain.
The only treatment shown to resolve CHS long-term is stopping cannabis use completely. Most people see real improvement within about ten days of quitting, though full recovery can take longer. Symptoms tend to come back if cannabis use resumes, even in smaller amounts than before.
When to Go to the ER
Call 911 or get to an emergency room if vomiting is paired with any of these:
- Dark urine or noticeably reduced urination
- Confusion or sudden disorientation
- Rapid heartbeat or breathing
- Fainting or severe dizziness
- Inability to keep down fluids for an extended period
