What Is ‘Scromiting’? Understanding the Terrifying Cannabis-Related Side Effect

‘Scromiting’ is a slang term combining the words “screaming” and “vomiting.” It describes episodes in which a person experiences extremely painful, repeated vomiting accompanied by intense abdominal pain, sometimes causing them to scream or cry out in distress.

The condition is associated with a medical disorder called Cannabinoid Hyperemesis Syndrome (CHS), which can develop in some people who use cannabis regularly over an extended period.

Although cannabis is commonly associated with relaxation, nausea relief and pain management, prolonged or frequent use can have the opposite effect in certain individuals: it can trigger severe, recurring nausea and vomiting.

Let’s look at what it is, why it happens, its symptoms, risk factors, treatment and what cannabis users should know.

1. What exactly is Scromiting?

Scromiting is not an official medical diagnosis. It is an informal name used to describe severe vomiting episodes associated with Cannabinoid Hyperemesis Syndrome (CHS).

CHS is a condition in which people who frequently use cannabis develop recurring episodes of:

• Severe nausea.

• Repeated, uncontrollable vomiting.

• Intense abdominal pain.

• Dry heaving (retching even when the stomach is empty).

• Difficulty keeping food and fluids down.

Some people experience vomiting so intensely that they cry, shout or scream because of the accompanying abdominal discomfort.

The condition can be particularly distressing because vomiting may continue repeatedly over several hours or even days.

2. Why does cannabis cause Scromiting?

This is one of the most surprising aspects of the condition.

Cannabis contains chemical compounds called cannabinoids. The best-known include:

• THC (tetrahydrocannabinol): The primary psychoactive compound responsible for the cannabis high.

• CBD (cannabidiol): A non-intoxicating cannabinoid that interacts with several biological systems.

The human body also has a natural network called the endocannabinoid system. It helps regulate several functions, including:

• Appetite.

• Digestion.

• Nausea and vomiting.

• Pain perception.

• Mood and sleep.

Cannabinoid receptors are found in the brain and gastrointestinal tract.

Cannabis can sometimes reduce nausea, which is why certain cannabinoid medicines are used in medical settings. However, prolonged and frequent cannabis exposure may disrupt the body’s normal regulation of nausea and vomiting in susceptible people.

Scientists have not yet established the exact biological mechanism behind CHS.

The leading explanation involves changes in cannabinoid receptor signalling, particularly after prolonged exposure to THC.

In simple terms:

Cannabis may initially reduce nausea, but in some long-term users, repeated exposure can eventually trigger severe nausea and vomiting instead.

This paradox is a defining feature of CHS.

3. What are the warning signs and symptoms?

CHS generally develops in stages. Recognising the early symptoms is important because the condition can become severe.

Stage 1: Prodromal phase (early warning stage)

This phase can last for months or even years.

• Morning nausea.

• Mild abdominal discomfort.

• Reduced appetite.

• Fear of vomiting.

• Feeling sick after waking up.

People may continue using cannabis because they believe it helps their nausea.

Stage 2: Hyperemetic phase (severe vomiting stage)

This is when scromiting can occur.

• Repeated vomiting.

• Severe abdominal pain.

• Intense nausea.

• Dry heaving.

• Difficulty eating or drinking.

• Excessive sweating.

• Signs of dehydration.

Some people repeatedly take hot showers or baths to temporarily relieve their symptoms.

Stage 3: Recovery phase

This phase begins after cannabis use is stopped.

• Vomiting gradually decreases.

• Appetite returns.

• Abdominal discomfort improves.

• Normal eating and drinking become easier.

Recovery can take days to months, depending on the individual and duration of cannabis abstinence.

4. Why do people with Scromiting take extremely hot showers?

One unusual characteristic of CHS is the strong desire to take hot showers or baths.

People experiencing severe symptoms sometimes spend hours in the bathroom because hot water temporarily reduces their nausea and abdominal discomfort.

Researchers believe heat may influence the body’s temperature-regulation pathways and pain signalling, potentially reducing symptoms temporarily.

However, there are important things to understand:

• Hot showers do not cure CHS.

• The relief is temporary.

• Symptoms may return after leaving the shower.

• Excessively hot water can cause burns.

• Prolonged hot bathing can worsen dehydration.

The association between compulsive hot bathing and CHS is well recognised, but it is not exclusive to CHS and cannot independently establish a diagnosis.

5. Who is most at risk?

Not everyone who uses cannabis develops CHS.

However, research suggests that the condition is particularly associated with people who:

1. Use cannabis frequently, especially daily or almost daily.

2. Have used cannabis for several years.

3. Consume products containing high concentrations of THC.

4. Began using cannabis during adolescence or early adulthood.

5. Continue using cannabis despite recurring nausea or vomiting.

Importantly, occasional cannabis use is not the typical pattern associated with CHS, although individual risk cannot be ruled out.

Does smoking marijuana, vaping or eating edibles make a difference?

CHS has been associated with different forms of cannabis consumption, including:

• Smoking marijuana.

• Vaping THC concentrates.

• Consuming cannabis edibles.

• Using high-potency cannabis extracts.

There is not enough evidence to establish that one consumption method is safe from CHS.

Switching from smoking to edibles or vaping should not be considered a reliable way to prevent the condition.

6. How serious is Scromiting? Can it be life-threatening?

Yes. Although many people recover after stopping cannabis, severe CHS can lead to dangerous medical complications.

The biggest immediate concern is dehydration caused by repeated vomiting.

7. How widespread is Scromiting in the United States?

CDC data – August 2026

The condition has attracted increased attention from U.S. health authorities.

According to a report published by the Centers for Disease Control and Prevention (CDC) on August 6, 2026, researchers examined emergency department visits involving Cannabinoid Hyperemesis Syndrome between January 2023 and May 2026.

The report found:

• Approximately 199,565 emergency department visits involving CHS were identified during the study period.

• Before October 2025, the average monthly rate was approximately 3.19 visits per 10,000 emergency department visits.

• Following the introduction of a specific diagnostic code for CHS in October 2025, the average rose to approximately 11.97 per 10,000 visits during October 2025–May 2026.

• Higher proportions were observed among younger people, particularly those aged 15–24.

• Females also showed higher proportions in the reported data.

An important clarification: This increase does not necessarily mean that CHS suddenly became 3.7 times more common. The CDC explains that improved diagnosis and reporting following the introduction of a dedicated medical code probably account for some of the increase.

These findings demonstrate that CHS is an important public health concern that has previously been underrecognised.

8. How is Scromiting diagnosed?

There is no single blood test that confirms CHS.

Doctors generally consider several factors:

1. A history of prolonged, frequent cannabis use.

2. Repeated episodes of severe nausea and vomiting.

3. Abdominal pain associated with the vomiting.

4. Temporary symptom relief from hot showers or baths.

5. Improvement after stopping cannabis.

Doctors may also conduct:

• Blood tests to check electrolytes and kidney function.

• Urine tests to assess hydration and other possible causes.

• Imaging tests when necessary to investigate abdominal problems.

• Other investigations to rule out gastrointestinal disorders.

One important challenge is that CHS can resemble other conditions, including cyclic vomiting syndrome, food poisoning, gastritis and intestinal disorders.

Therefore, a proper medical assessment is essential.

9. What is the treatment for Scromiting?

The most important treatment is complete cessation of cannabis use.

There is currently no established medication that permanently cures CHS while someone continues using cannabis.

Treatment generally involves three approaches.

A. Stop cannabis consumption

This is the only established long-term solution.

People diagnosed with CHS should stop using cannabis products, including THC-containing edibles, concentrates and other forms.

Continuing to use cannabis can trigger further episodes.

B. Treat dehydration

For people experiencing severe vomiting, hospital treatment may include:

• Intravenous (IV) fluids.

• Electrolyte replacement.

• Monitoring of kidney function.

• Medical treatment for nausea and vomiting.

C. Manage acute symptoms

Doctors may consider treatments such as:

• Haloperidol or droperidol.

• Topical capsaicin cream.

• Conventional anti-nausea medications, although these are not always effective.

The appropriate treatment depends on the person’s condition and medical history. These medications should be administered under medical supervision.

10. Can Scromiting be prevented?

Yes. The most reliable way to prevent CHS is to avoid cannabis.

For people who already have CHS, sustained abstinence is particularly important.

Other useful precautions include:

• Do not ignore repeated morning nausea.

• Seek medical assessment for recurring vomiting or abdominal pain.

• Be honest with healthcare professionals about cannabis consumption.

• Do not assume that switching to vaping or edibles will prevent CHS.

• Seek help if stopping cannabis is difficult.

It is also important to remember that cannabis products marketed as natural or medically beneficial are not necessarily free of adverse effects.

11. Is Scromiting permanent?

In most cases, CHS symptoms can resolve after cannabis consumption stops.

However, recovery varies.

• Some people improve within several days.

• Others may need weeks or longer.

• Symptoms can return if cannabis consumption resumes.

Continued cannabis use can cause repeated episodes, potentially resulting in multiple emergency department visits.

Long-term recovery generally requires sustained cannabis abstinence.

12. Scromiting versus ordinary cannabis side effects

13. What should cannabis users understand?

There are three particularly important lessons.

First: Cannabis does not affect everyone in the same way. Some people may use it without developing CHS, while others develop severe symptoms after prolonged use.

Second: Repeated vomiting should never be dismissed as an ordinary cannabis reaction. It may indicate CHS or another potentially serious medical condition.

Third: Continuing cannabis to relieve nausea can make CHS worse. This is one of the most confusing aspects of the condition because cannabis itself is sometimes used to treat nausea in other medical circumstances.

14. Reliable medical sources and further reading

Final takeaway

Scromiting is more than an unpleasant cannabis side effect. It is a term describing a particularly distressing manifestation of Cannabinoid Hyperemesis Syndrome, a condition associated with prolonged and frequent cannabis consumption.

Although researchers are still investigating exactly why cannabis triggers this reaction in some people, the medical evidence establishes an important message: frequent cannabis use can paradoxically cause severe nausea, repeated vomiting and abdominal pain.

The good news is that CHS is generally reversible with sustained cannabis cessation. Early recognition and appropriate medical treatment can also prevent dangerous complications such as severe dehydration and kidney injury.

The CDC’s 2026 findings make awareness especially important, particularly among younger cannabis users.
