Many people assume cannabis is a safe and gentle plant, especially as laws change and more places allow casual use. Yet doctors warn that a hidden risk is showing up far more often than most users realize. The condition is known as scromiting, a dramatic mix of screaming and vomiting that can strike long-term cannabis users without much warning. It may sound extreme, but emergency rooms report sharp increases in cases tied to heavy marijuana habits, and many specialists believe the problem deserves more attention.
People who develop scromiting usually say the symptoms start quietly. They feel waves of nausea or mild stomach cramps that seem easy to ignore at first. Over time, though, the discomfort grows until vomiting becomes frequent and sometimes nonstop. Doctors now link this pattern to Cannabis Hyperemesis Syndrome, which appears mainly in people who use strong marijuana products every day or almost every day. This can surprise users because cannabis is often praised for easing nausea, yet heavy and long-term exposure can create a very different reaction in the body.
Why This Condition Surprised Doctors
Doctors were confused for years. It simply did not make sense to see cannabis patients coming into urgent care with uncontrollable vomiting. After all, marijuana had a long reputation as something that helps ease nausea, not cause it. Yet as legalization expanded and stronger THC products hit the market, emergency room physicians noticed repeating patterns. People showed up with the same pain, the same vomiting cycles, and the same strange habit.

This detail actually helped researchers connect the dots. Over time, studies started showing how long-term cannabis use might overwhelm parts of the nervous system, especially the systems that control digestion and body temperature. When those pathways get overloaded, they can fire off mixed messages that cause severe nausea. Hot water, for reasons still being studied, activates skin receptors that distract the brain and give the stomach a temporary break. The relief does not fix anything, but it helps patients get a tiny bit of comfort in the middle of the crisis.
Cannabis today is a lot stronger than it was decades ago. Concentrates and vape oils deliver levels of THC that older generations of users never encountered. Doctors think this rise in potency is one reason Cannabis Hyperemesis Syndrome is growing. Even though only a portion of heavy users will ever deal with scromiting, the number is growing fast, and hospitals are trying to catch up.
How Scromiting Usually Begins
The symptoms do not arrive suddenly. They build up over years of steady use, especially for people who smoke every morning, afternoon, and night. The first phase, which some call the prodromal phase, seems mild enough that many people shrug it off. You might wake up with nausea. Or maybe you lose your taste for breakfast even though you used to enjoy it. Sometimes there is a sense that food just sits wrong in the stomach. It comes and goes, so most people ignore it.

Because cannabis seems like it should soothe nausea, people often respond by using more. This creates a cycle without them noticing. Eventually, the discomfort shifts into the hyperemetic phase, which is when scromiting really shows itself. The stomach starts to cramp hard. Vomiting becomes constant. Some people describe it as their stomach emptying repeatedly, even when nothing remains. Others say they feel heat rushing across their skin, followed by sharp abdominal pain that knocks them off their feet.
This is the stage where emergency care is almost always needed. At this point, dehydration becomes serious. Some people develop kidney issues or lose electrolytes at a dangerous rate. Anti-nausea medications that help with regular stomach problems often do not work well here. Instead, doctors use fluids, capsaicin cream on the abdomen, and sometimes anti-anxiety medication to calm the system. These treatments help a bit, but stopping cannabis is the only true fix for Cannabis Hyperemesis Syndrome.
Why Hot Showers Offer Strange Comfort
One part of this condition that still surprises people is how powerful hot water becomes. When someone is stuck in the worst part of scromiting, a hot shower might be the only thing that gives any relief. The heat activates specific receptors in the skin that compete with nausea signals traveling through the brain. This does not solve the underlying problem, but it gives the nerves something else to focus on, so the vomiting cycle slows for a short time.

Because this behavior is so distinct, many doctors use it as a clue. When a patient says they spend hours in the shower during these attacks, it helps the medical team rule out infections or other stomach issues. This tiny detail has improved diagnosis rates, helping hospitals recognize Cannabis Hyperemesis Syndrome faster than they did just a few years ago.
Who Is Most at Risk
While anyone who uses cannabis daily could face this condition, certain groups show up more often. People who use high-potency products like dabs or strong vape oils seem to face a higher risk. Younger adults, especially those who started using during their teenage years, are also more likely to develop symptoms later. There may be a genetic aspect too, because some people seem more sensitive to THC’s long-term effects than others. Tolerance also plays a part. As users need more cannabis to feel the same effects, their bodies take on more strain, which increases the chances of triggering Cannabis Hyperemesis Syndrome.
Why This Marijuana Side Effect Is Often Missed
CHS can be confusing because it does not follow the usual pattern of stomach illness. Symptoms fade and return over and over. Some people go to the hospital several times before anyone mentions cannabis. Others hesitate to admit how much they use, which makes diagnosis slower. Even today, many people have never heard of scromiting, so they have no idea their cannabis habit could be part of the problem. This makes the condition easier to miss than it should be.

What Doctors Look For During Diagnosis
When someone arrives at an emergency room with nonstop vomiting, doctors run through many possibilities. They test for infections, gallbladder issues, blockages, and sometimes hormonal problems. It is not unusual for people with Cannabis Hyperemesis Syndrome to undergo multiple scans before the real cause becomes clear. Some patients even have their appendix checked because the pain can feel sharp and severe.
However, once a doctor hears about heavy cannabis use, especially paired with long hot showers, the picture becomes clearer. Not every hospital is familiar with scromiting, but awareness grows each year. Doctors say this condition is still often missed because many people underestimate their own marijuana habits. They might say they use casually, when in reality they vape or smoke several times a day without noticing how often it happens.
Some clinicians also mention that patients feel embarrassed discussing cannabis use. They worry about being judged, so they share only part of the truth. This makes it harder to connect all the details. Still, when the pattern appears frequently enough, doctors recognize the symptoms even when patients hesitate.
Treatment Options That Help During an Attack
Once CHS is identified, the focus shifts toward stabilizing the patient. Vomiting drains the body of fluids and salt quickly, and this becomes dangerous if not treated fast. The first step is usually IV fluids to restore balance. People often feel weak, shaky, or confused because of dehydration, so rehydration helps restore strength.

Capsaicin cream sometimes provides relief by activating skin receptors in a way similar to hot water. It may burn slightly at first, but for many patients it reduces the stomach signals that trigger vomiting. Some doctors also use medications to relax the nervous system because anxiety grows as the cycle continues. When the body calms down, the vomiting sometimes slows too.
However, even with all these treatments, the symptoms often return if someone continues using cannabis. That reality can be hard to accept for many people because cannabis plays such a big role in daily routines. Some use it to sleep, others to handle stress or chronic pain. So the idea of stopping may feel overwhelming. Still, stopping cannabis remains the only proven way to break the cycle of Cannabis Hyperemesis Syndrome.
How People Recover After Stopping Cannabis
Once someone quits cannabis, the body usually begins healing faster than expected. Many people notice improvements within one or two days. The nausea lightens. Vomiting stops. Energy returns slowly as the body repairs itself. This recovery phase can last several weeks, and during that time, the appetite often returns with surprising strength.
Some people say they did not realize how constant their stomach discomfort had become until it disappeared. Others feel nervous that the symptoms may return, but once cannabis is removed from daily life, the cycle tends to end. If someone uses cannabis again, though, the symptoms can return quickly. That is why doctors warn people to avoid any kind of marijuana while recovering.
Why Some Users Ignore the Warning Signs
Even with growing awareness, many people push aside early symptoms because they believe cannabis helps them. They feel it relaxes their stomach, so when nausea starts, they smoke more. This creates a misunderstanding where the user feels like the cannabis is soothing the problem, not causing it. Because the relief from hot showers is so dramatic, people assume their symptoms must be something unrelated. By the time vomiting becomes nonstop, they are shocked that cannabis might be the source.
Online groups and social media have become places where people compare stories and discover this condition together. Many say they did not learn about scromiting until they searched the internet after repeated hospital visits. They often express confusion and frustration because nobody warned them earlier, even though cannabis looks harmless from the outside.
The Larger Public Health Conversation
As marijuana laws change and new products continue to grow stronger, health experts say it is important to talk about Cannabis Hyperemesis Syndrome with honesty. The goal is not to scare people away from cannabis. Instead, it is to help everyone understand how the body reacts when exposed to powerful substances every day. Many people see cannabis as natural and calming, so they think nothing bad will happen. But nature does not always mean harmless, and long-term exposure to high levels of THC can place real pressure on systems that quietly keep the body balanced.

Doctors and researchers also believe the rise of scromiting cases teaches us something about modern cannabis culture. People use more now than ever. They use stronger products. They also see cannabis as something without serious risks, which is not fully accurate. Like any drug, it has side effects that deserve attention. When people know the signs early, they can protect themselves from reaching the severe stages of vomiting and pain.
How Families and Friends Can Support Someone With CHS
Watching someone go through Cannabis Hyperemesis Syndrome can be frightening. They may look exhausted, dehydrated, or overwhelmed. Friends and family can support them by encouraging rest, helping them access medical care, and staying calm when symptoms grow tough. Once the person learns that cannabis is causing the cycle, they may feel confused or even defensive. That reaction is normal. Change is hard, especially when cannabis plays a role in managing stress.
Loved ones can help by offering nonjudgmental support. Simple things like preparing light meals, suggesting hydration, or helping remove cannabis products from the home can make a big difference. Encouraging honest conversations with doctors also helps the recovery process move faster.

What Researchers Still Do Not Know
Even though doctors understand the basic pattern of CHS, many details remain unclear. Researchers are still studying why some heavy users develop scromiting while others never do. They are also trying to understand which parts of the brain are involved, and why THC flips from easing nausea to causing it. There are questions about genetics, metabolism, and body chemistry that scientists have not fully answered yet.
What is known for sure is that the condition disappears when cannabis use ends. That simple fact points toward a direct relationship between marijuana and the symptoms, even if some details of the mechanism are still being explored.

The Emotional Impact of Scromiting
The physical pain of Cannabis Hyperemesis Syndrome is intense, but the emotional impact can be strong too. Some people feel frustrated or ashamed because they never imagined cannabis could hurt them. Others feel anxious once they realize their daily routine must change. There can even be grief, especially for people who relied on cannabis for comfort.
Talking openly about the experience can help. Support groups, counseling, or honest conversations with loved ones can make the adjustment smoother. People who recover often say they feel stronger, healthier, and more aware of their body’s cues after going through the process.
Final Thoughts
The rise in Cannabis Hyperemesis Syndrome shows that marijuana has effects we still do not fully understand, and even doctors admit they are learning as they go. When someone deals with repeated nausea or sudden vomiting, it is easy to blame stress or a random stomach bug, but ignoring the signs usually makes the situation harder.
If these symptoms keep showing up, it is worth paying attention and being honest about cannabis habits because that is the fastest way to get proper help. Most people improve once they stop using marijuana, and knowing what is going on gives them a better chance to feel normal again. Talking openly about the issue may feel uncomfortable, but it helps people protect their health and avoid being caught off guard by something they never expected.
