Cannabis is often associated with relaxation, an increased appetite, and a feeling of calm. But for some frequent users, long-term consumption can lead to a surprising and potentially serious condition involving repeated vomiting and intense abdominal pain.
The condition is known as cannabinoid hyperemesis syndrome (CHS). Its more dramatic nickname,
scromiting, combines the words “screaming” and “vomiting” to describe episodes in which severe pain and uncontrollable vomiting may cause a person to scream in distress. <Cite refs={["turn244103search0","turn244103search5"]}/>
Although the term sounds alarming, understanding the condition can help people recognize warning signs, seek appropriate treatment, and prevent dangerous complications.
What Exactly Is Scromiting?
Scromiting is an informal term, not a separate medical diagnosis. It describes severe episodes of vomiting and distress that can occur in people experiencing cannabinoid hyperemesis syndrome.
CHS is associated with prolonged, frequent cannabis use. It can cause recurring bouts of intense nausea, vomiting, and stomach pain, sometimes severe enough to require emergency medical treatment. <Cite refs={["turn244103search2","turn244103search8"]}/>
One particularly confusing aspect of the condition is that cannabis is sometimes used to relieve nausea. However, in susceptible people, frequent long-term use can be associated with the opposite effect.
Researchers do not yet fully understand why CHS develops. Cannabis contains compounds that interact with the body's endocannabinoid system, which plays a role in processes including appetite, digestion, and nausea. Repeated exposure may disrupt normal regulation in some individuals, but the precise mechanism remains under investigation. <Cite refs={["turn244103search0","turn244103search2"]}/>
Why Is the Condition Receiving Attention in the United States?
Health professionals have become increasingly attentive to cannabis hyperemesis syndrome as cannabis use has become more widespread.
A CDC report published in August 2026 examined U.S. emergency department visits involving CHS from January 2023 through May 2026. It found a marked increase in the proportion of visits identified as involving the condition after a dedicated diagnostic code was introduced in October 2025.
Importantly, this increase may partly reflect improved recognition and reporting rather than a sudden rise in the number of people developing the condition. The CDC also highlighted the need for greater public awareness and better clinical recognition. <Cite refs={["turn244103search4","turn244103search23"]}/>
The message is not that every cannabis user will develop CHS. Rather, frequent use carries risks that people should understand, including the possibility of severe recurring gastrointestinal symptoms.
What Are the Main Symptoms?
Symptoms can develop gradually and may become more severe over time. Recognizing the pattern is important because people sometimes mistake the early signs for an ordinary stomach bug.
1. Persistent nausea
Some people initially experience nausea, particularly in the morning. They may have little appetite or feel uncomfortable after eating.
These early symptoms can persist or recur for weeks or months before a more severe episode develops.
2. Repeated, uncontrollable vomiting
The characteristic symptom of CHS is repeated vomiting that may occur in intense bouts. During a severe episode, a person may struggle to keep even small amounts of fluid down.
This can lead to dehydration and dangerous disturbances in the body's electrolyte balance.
3. Severe abdominal pain
People with CHS may experience significant stomach discomfort or abdominal pain alongside nausea and vomiting.
Because many other conditions can cause similar symptoms, a medical professional should evaluate severe or persistent abdominal pain rather than automatically attributing it to cannabis.
4. Temporary relief from hot showers
A notable feature of CHS is that some affected people report temporary relief from nausea or abdominal discomfort when taking a hot shower or bath.
However, this is not a definitive diagnostic test. Other conditions can cause similar symptoms, and not everyone with CHS experiences this effect. Prolonged exposure to very hot water can also cause burns or worsen dehydration. <Cite refs={["turn244103search0","turn244103search6"]}/>
Who Is Most at Risk?
CHS is most strongly associated with frequent, long-term cannabis use, particularly daily or near-daily consumption over an extended period.
However, researchers cannot predict with certainty who will develop the condition. Not everyone who uses cannabis frequently experiences CHS, and the absence of symptoms today does not guarantee that they will never occur. <Cite refs={["turn244103search2","turn244103search3"]}/>
Cannabis products also vary in their THC concentration and composition. The relationship between specific products, dosage, and individual susceptibility remains an area of ongoing research.
People who experience recurring nausea, vomiting, or abdominal pain should tell their healthcare professional about their cannabis use. Honest information can help clinicians assess CHS alongside other possible causes.
Why Can Scromiting Become Dangerous?
The most immediate danger is often not the vomiting itself but the complications that repeated episodes can cause.
Dehydration
Frequent vomiting prevents the body from retaining enough fluid. Warning signs include intense thirst, dry mouth, dizziness, unusual weakness, and passing very little urine.
Electrolyte imbalances
Vomiting can disrupt the levels of important minerals in the blood, including potassium and sodium. Severe imbalances may affect muscle function, kidney function, and heart rhythm.
Kidney problems
Severe dehydration can reduce blood flow to the kidneys and cause acute kidney injury.
Damage caused by repeated vomiting
Persistent vomiting can irritate or injure the esophagus and contribute to dental enamel erosion over time.
These complications are documented medical concerns, and severe cases may require hospital treatment. <Cite refs={["turn244103search0","turn244103search8"]}/>
Seek urgent medical care if someone cannot keep fluids down, has very little urine, becomes faint or confused, experiences severe abdominal pain, or develops chest pain or difficulty breathing. Do not wait for the symptoms to become unbearable.
How Is Cannabinoid Hyperemesis Syndrome Treated?
Treatment depends on the severity of the symptoms and the person's overall condition.
During a severe episode, healthcare professionals may provide intravenous fluids, correct electrolyte abnormalities, and use appropriate medication to help control symptoms.
Other causes of vomiting may need to be investigated, because CHS cannot be confirmed from symptoms alone. A clinician may ask about the frequency and duration of cannabis use and, when appropriate, order blood tests or other investigations. <Cite refs={["turn244103search0","turn244103search6"]}/>
Stopping cannabis is essential for long-term recovery
The most effective established long-term treatment for CHS is complete cessation of cannabis use. Symptoms often improve after stopping, although recovery time varies and may take days to weeks or longer.
Continuing to use cannabis can cause symptoms to return. People who find it difficult to stop should seek support from a healthcare professional or an appropriate substance-use service. <Cite refs={["turn244103search0","turn244103search2"]}/>
Hot showers, home remedies, or medications that temporarily ease nausea should not be mistaken for a cure.
Can Scromiting Be Prevented?
The only established way to prevent cannabis hyperemesis syndrome is to avoid cannabis use. For someone who has already developed CHS, stopping cannabis completely is the key preventive measure against further episodes.
If a person uses cannabis regularly and starts experiencing recurring nausea or unexplained vomiting, they should seek medical advice early rather than increasing their consumption in an attempt to relieve the symptoms.
It is also important to remember that not all vomiting in a cannabis user is CHS. Gastrointestinal infections, medication effects, pregnancy, and other medical conditions can produce similar symptoms and may require different treatment.
The Bottom Line
Scromiting is a dramatic nickname for the distressing vomiting and pain that can occur with cannabinoid hyperemesis syndrome. The underlying condition is associated with frequent, long-term cannabis use and can lead to serious complications if severe vomiting is left untreated.
Although researchers are still studying exactly why CHS develops, the practical message is clear: recurring nausea and vomiting should not be ignored, and severe symptoms require prompt medical attention.
For people affected by CHS, stopping cannabis is the most effective established way to achieve lasting recovery and prevent further episodes.
