“Scromiting” is a nickname for severe vomiting accompanied by intense pain or screaming. Learn how it relates to cannabinoid hyperemesis syndrome, its warning signs and when emergency care is needed.

The word “scromiting” sounds unusual—even shocking—but it describes a very real and potentially serious medical problem associated with frequent cannabis use.

The term combines “screaming” and “vomiting” and is used to describe episodes in which a person experiences relentless vomiting and severe abdominal discomfort or distress. Doctors generally associate this pattern with a condition called cannabinoid hyperemesis syndrome (CHS).

CHS isn’t simply an ordinary upset stomach. Severe episodes can lead to dehydration, electrolyte abnormalities and acute kidney injury, sometimes requiring emergency treatment.

What Is Cannabinoid Hyperemesis Syndrome?

Cannabinoid hyperemesis syndrome is a condition associated with frequent, long-term cannabis use.

People with CHS can experience repeated cycles of:

• Nausea
• Severe vomiting
• Abdominal pain
• Dry heaving
• Dehydration
• Difficulty keeping fluids down

One of the unusual clues is that some people with CHS report temporary relief from very hot showers or baths.

The exact biological mechanism behind CHS is still not completely understood.

So, What Exactly Does “Scromiting” Mean?

“Scromiting” isn’t the formal medical diagnosis.

It’s an informal term used to describe particularly intense episodes of vomiting in which the person may cry out or scream because of severe nausea and abdominal pain.

In other words, scromiting is a nickname—not a separate disease.

The underlying condition doctors are concerned about is cannabinoid hyperemesis syndrome.

Who Is Most at Risk?

CHS is most strongly associated with heavy or frequent cannabis use over a prolonged period.

The American College of Gastroenterology notes that CHS usually develops after years of marijuana use occurring many times per week.

Not everyone who uses cannabis develops CHS, and researchers still don’t fully understand why some frequent users develop it while others do not.

The Early Warning Signs May Be Easy to Miss

CHS can develop in stages.

During an earlier phase, a person may experience:

• Recurrent nausea, particularly in the morning
• Mild abdominal discomfort
• Fear of vomiting
• Reduced appetite
• Increasing reliance on hot showers for symptom relief

At this point, the symptoms may be mistaken for an ordinary stomach problem.

Eventually, some people progress to the hyperemetic phase, when vomiting becomes severe and repeated.

Why Do Hot Showers Seem to Help?

One of the most recognizable features of CHS is the unusual behavior of taking repeated hot showers or baths.

Some people report that hot water temporarily eases their nausea and abdominal discomfort.

Researchers aren’t completely certain why this happens. The effect may involve the body’s temperature-sensing pathways and cannabinoid signaling.

Importantly, hot showers don’t treat the underlying condition. Excessively hot water can also cause burns or worsen dehydration.

Why Can CHS Become Dangerous?

The greatest immediate concern is often dehydration.

Someone who vomits repeatedly may lose substantial amounts of fluid and electrolytes.

Severe cases can lead to:

• Very low urine output
• Dark urine
• Dizziness
• Rapid heartbeat
• Weakness
• Electrolyte disturbances
• Acute kidney injury
• Fainting

Repeated forceful vomiting can also injure the esophagus and, rarely, cause other serious complications.

Why Are Emergency Departments Seeing More Cases?

Recent reporting has drawn attention to a substantial increase in emergency-department presentations associated with cannabinoid hyperemesis syndrome.

The Association of American Medical Colleges reported in July 2026 that CHS had increased by more than 500% since 2016, while emergency physicians described seeing more patients with severe cannabis-related vomiting.

A large analysis of emergency-department data has also found a sharp increase in CHS diagnoses over the years studied.

These trends don’t mean every person who uses cannabis will develop CHS. Rather, they highlight why doctors are increasingly aware of the condition.

Why Can CHS Be Difficult to Recognize?

There are many possible causes of severe nausea and vomiting.

A person may initially be evaluated for:

• Food poisoning
• Gastroenteritis
• Gallbladder problems
• Pancreatitis
• Appendicitis
• Stomach ulcers
• Other gastrointestinal conditions

Doctors may need blood tests, imaging or other investigations to rule out alternative causes.

That’s why it is important for patients to tell healthcare professionals honestly about cannabis use. This information can be an important diagnostic clue.

Does Stopping Cannabis Help?

Yes.

For people with CHS, stopping cannabis use is the most important step toward recovery.

Symptoms can improve after cannabis is discontinued, although recovery may take time. Returning to cannabis use can cause symptoms to return.

There is currently no reliable way to prevent CHS while continuing the cannabis use that triggers it.

When Should Someone Go to the ER?

Severe or repeated vomiting should not be ignored.

Emergency medical care is particularly important if someone:

• Cannot keep fluids down
• Is barely urinating
• Has very dark urine
• Becomes severely dizzy or weak
• Faints
• Has a very rapid heartbeat
• Develops confusion
• Has severe abdominal pain
• Has blood in the vomit
• Develops chest pain or difficulty breathing

These symptoms can indicate dehydration or another potentially serious medical problem.

Is Every Episode of Vomiting After Cannabis CHS?

No.

Vomiting can have many causes, and cannabis use alone doesn’t prove that someone has CHS.

Doctors look for a characteristic pattern involving frequent cannabis exposure, recurrent nausea and vomiting, abdominal symptoms and improvement after stopping cannabis.

Other medical causes need to be considered as well.

The Bottom Line

“Scromiting” is an attention-grabbing word, but behind it can be a serious medical condition.

Cannabinoid hyperemesis syndrome (CHS) is associated with frequent, long-term cannabis use and can cause cycles of severe nausea, abdominal pain and repeated vomiting. In serious cases, dehydration, electrolyte problems and kidney injury can occur.

If someone who regularly uses cannabis begins experiencing repeated vomiting—especially if hot showers temporarily relieve the symptoms—CHS should be considered and discussed with a healthcare professional.

The most important treatment is stopping the cannabis use associated with the condition, while severe dehydration or other complications may require emergency medical care.
