In the era of widespread legalization and the normalization of high-potency THC products, the public narrative surrounding marijuana is often one of harmless relaxation. But inside America’s emergency rooms, a far more volatile reality is unfolding. Medical professionals nationwide are sounding the alarm on a brutal, debilitating condition that is sending long-term users to the hospital in droves—a phenomenon so violent it has earned the visceral medical moniker: “scromiting.”
While the word itself sounds like a dark internet joke, the reality is a clinical horror story.
Over the past decade, emergency departments have witnessed a dramatic surge in patients afflicted by a relentless cycle of severe nausea, intractable vomiting, and abdominal pain so excruciating it leaves them completely incapacitated. This isn’t a bad trip or a simple case of “greening out”; it is the devastating onset of Cannabis Hyperemesis Syndrome (CHS), a condition that is baffling patients and draining their bank accounts.
“A person often will have multiple emergency department visits until it is correctly recognized, costing thousands of dollars each time,” warns Dr. Beatriz Carlini, a research associate professor at the University of Washington School of Medicine.
The Anatomy of a Crisis: When the Sickness Makes You Scream
The term “scromiting” was born directly out of the desperation heard on the frontlines of emergency medicine. Frontline staff coined the portmanteau because the physical toll on patients is so intense that they are quite literally screaming in agony while actively vomiting.
These brutal CHS attacks typically strike within a 24-hour window of cannabis consumption and can hold a patient hostage for days at a time.
Compounding the terror of the syndrome is how stubbornly resistant it is to traditional medicine. Emergency specialists find themselves in a frustrating therapeutic corner.
“There are currently no therapies approved by the Food and Drug Administration, and standard anti-nausea medications often don’t work,” explains Dr. Chris Buresh, an emergency medicine specialist.
Faced with ineffective standard treatments, doctors have had to resort to an unconventional arsenal of remedies. They frequently use Haldol—an antipsychotic medication typically reserved for acute psychotic episodes—or apply topical capsaicin cream directly to the patient’s abdomen.
Perhaps the most telling diagnostic tool, however, is a simple plumbing fixture. Sufferers quickly discover that the only thing providing temporary relief is scorching heat.
“That’s something that can clinch the diagnosis for me, when someone says they’re better with a hot shower,” Dr. Buresh notes. “Patients describe going through all the hot water in their house.”
The Rebound Trap: Who is Vulnerable?
The insidiousness of CHS lies in its cyclical, deceptive nature. Because the attacks strike intermittently rather than continuously, many users fall into a dangerous cognitive trap. When a violent episode finally subsides, they assume the sickness was caused by bad food, a stomach bug, or a temporary fluke—completely unrelated to their cannabis use. They light up again, unknowingly resetting the clock on their next violent relapse.
Medical experts are clear: while temporary fixes can dull the pain, long-term recovery requires complete, permanent abstinence from cannabis. But in an era where dependence is real, quitting is often easier said than done.
Scientifically, CHS remains a frustrating puzzle. Researchers are still trying to map out exactly why the syndrome targets certain individuals while leaving others untouched.
The prevailing medical theory points toward a system overload. Prolonged exposure to heavy doses of THC can overstimulate the body’s endocannabinoid system, essentially short-circuiting the neural pathways that naturally regulate nausea and vomiting.
“It seems like there’s a threshold when people can become vulnerable to this condition, and that threshold is different for everyone,” says Dr. Buresh. “Even using in small amounts can make these people start throwing up.”
The Data: A Tenfold Jump Among Teens
The scope of this public health shift is underscored by a major study out of George Washington University. Surveying more than 1,000 CHS patients, researchers established an undeniable, definitive link between early, prolonged cannabis consumption and subsequent ER visits for scromiting.
Even more troubling is the demographic shift toward youth. Between 2016 and 2023, adolescent cases of CHS in the United States skyrocketed more than tenfold.
Geographically, the data reveals a fascinating paradox:
-
Legal States: While overall cases of CHS remain more prevalent in states with fully legalized recreational cannabis frameworks, the trend flips significantly when looking at minors.
-
Illegal States: The sharpest, most aggressive spike in underage hospitalizations for scromiting is actually occurring in states where recreational marijuana remains strictly illegal.
The Official Verdict: The Medical World Responds
The escalating crisis has forced global health organizations to finally codify the disease. On October 1, 2025, the World Health Organization officially recognized Cannabis Hyperemesis Syndrome, assigning it a dedicated, distinct diagnosis code.
This formal recognition is far more than a bureaucratic milestone; it is a critical tool for tracking the reality of the crisis.
“A new code for cannabis hyperemesis syndrome will supply important hard evidence on cannabis-adverse events, which physicians tell us is a growing problem,” Dr. Carlini explains.
As emergency room admissions continue their steady climb, public health experts emphasize that the era of treating cannabis as a entirely consequence-free substance must come to an end. For both the teenagers experimenting in secret and the adults using daily, awareness of CHS isn’t just a matter of education—it is a necessary shield against a profoundly debilitating condition.
