Cannabis hyperemesis syndrome (CHS) is a medical condition that arises from long-term and heavy cannabis (marijuana) use. Individuals afflicted with CHS regularly experience distressing episodes characterized by severe nausea, vomiting, dehydration, and abdominal pain, often necessitating repeated visits to the emergency department for relief.
The term “hyperemesis” denotes a state of severe and persistent vomiting. CHS is also referred to as cannabinoid hyperemesis syndrome. Cannabinoids are chemical compounds present in the cannabis plant, and they interact with cannabinoid receptors found in various parts of our bodies, including the brain, gastrointestinal tract, and immune cells. Among the most extensively researched exogenous cannabinoids are tetrahydrocannabinol (THC), cannabidiol (CBD), and cannabigerol (CBG).

It’s important to emphasize that CHS transcends being a mere side effect of marijuana use. Instead, it represents a distinct medical condition that can give rise to significant health complications if not addressed promptly and appropriately. Understanding CHS is pivotal for those who engage in cannabis consumption to recognize its symptoms and seek appropriate care promptly.
How Common Is Cannabis Hyperemesis Syndrome (CHS)?
Cannabis hyperemesis syndrome (CHS) has only recently gained recognition as a distinct medical condition. Consequently, its exact prevalence is not yet fully understood. However, it appears to affect a relatively small proportion of individuals who engage in heavy and long-term marijuana use. It’s plausible that many more people could be experiencing CHS but may not have received appropriate medical attention or have been misdiagnosed.
A study conducted on this subject found that approximately 6% of individuals who sought medical care at an emergency room for symptoms of vomiting were diagnosed with CHS. This figure underscores that while CHS is not widespread, it is a noteworthy medical issue that healthcare providers need to be aware of, especially in the context of patients with a history of heavy marijuana use who exhibit symptoms of severe vomiting and related distress.
What are the symptoms of Cannabis hyperemesis syndrome (CHS)?
Cannabis hyperemesis syndrome (CHS) is characterized by a set of distinct and recurring symptoms. The primary and most notable symptoms include severe and persistent nausea and vomiting. Individuals afflicted with Cannabis hyperemesis syndrome may endure frequent and intense vomiting episodes, which can occur suddenly and may happen as frequently as up to five times per hour. Alongside this, they often experience generalized abdominal pain, report unexplained weight loss, and exhibit signs of dehydration.
Notably, people with Cannabis hyperemesis syndrome often discover that hot showers provide some relief from their nausea, and they may resort to compulsive showering or bathing as a coping mechanism. This can lead to hours-long bathing sessions daily to alleviate the symptoms of cannabis hyperemesis syndrome.

CHS unfolds in three distinct phases, each with slightly varying symptoms:
1. Prodromal Phase: This initial phase is more common in adults who have been using cannabis since their teenage years. Symptoms may include abdominal pain and morning nausea. Individuals may have a fear of vomiting but may not vomit during this phase.
2. Hyperemetic Phase: Typically lasting for a duration of 24 to 48 hours, this phase is marked by overwhelming, recurrent bouts of vomiting and nausea. Individuals in this phase may start compulsively bathing, avoid certain foods, or intentionally limit their food intake.
3. Recovery Phase: In the recovery phase, individuals cease using cannabis altogether, even in small amounts. Symptoms gradually lessen over a few days or months and eventually disappear entirely, marking the resolution of cannabis hyperemesis syndrome.
Understanding these distinct phases and their associated symptoms is crucial for the diagnosis and management of CHS. It’s important to note that the symptoms of Cannabis hyperemesis syndrome can be severe and debilitating, making early recognition and intervention essential for affected individuals.
What Causes Cannabinoid Hyperemesis Syndrome?
Cannabinoid Hyperemesis Syndrome (CHS) is a perplexing condition linked to prolonged cannabis use. Individuals afflicted by CHS suffer recurrent bouts of nausea, vomiting, dehydration, and abdominal pain, often necessitating multiple trips to the emergency department.
The term “hyperemesis” refers to severe vomiting, hence CHS is also known as cannabinoid hyperemesis syndrome. Cannabinoids, which are chemical compounds found in the cannabis plant, interact with cannabinoid receptors in the brain, gastrointestinal system, and immune cells. Notable cannabinoids include tetrahydrocannabinol (THC), cannabidiol (CBD), and cannabigerol (CBG). It’s essential to recognize that CHS is more than just a marijuana side effect; it’s a distinct condition with the potential to lead to health complications if left untreated.

CHS was only recently identified as a medical condition, and it’s primarily observed in a small percentage of heavy cannabis users. Many affected individuals may go undiagnosed or receive a misdiagnosis. One study indicates that approximately 6% of people seeking emergency medical care for vomiting may have CHS.
The hallmark symptoms of CHS encompass severe and persistent nausea and vomiting. These individuals frequently experience intense, unexpected vomiting episodes, sometimes up to five times per hour. They often report diffuse abdominal pain, weight loss, and signs of dehydration.
One unusual coping mechanism observed among people with CHS is their tendency to take long, hot showers to alleviate nausea. In some cases, individuals with CHS may compulsively shower or bathe for hours each day to find relief from their symptoms.
CHS manifests in three distinct phases, each characterized by varying symptoms:
1. Prodromal Phase: Common in adults who have used cannabis since their teenage years, this phase may involve symptoms like abdominal pain and morning nausea, with the fear of vomiting without actually doing so.
2. Hyperemetic Phase: Typically lasting 24 to 48 hours, individuals in this phase experience relentless, recurrent vomiting and nausea. They often develop a compulsion for bathing and may avoid certain foods or restrict their diet.
3. Recovery Phase: During this phase, individuals cease cannabis use, even in small quantities. Over several days to months, symptoms gradually diminish, eventually disappearing entirely.

While CHS may seem paradoxical given that cannabis is often associated with alleviating nausea and vomiting, the complex interaction between cannabinoids and the body’s various receptors is believed to contribute to this condition. Continued research is crucial to unravel the mechanisms of CHS and to provide effective management strategies for affected individuals.
To address Cannabinoid Hyperemesis Syndrome (CHS), particularly during the intense vomiting phase, individuals may require medical care, and in some cases, hospitalization. The treatments during the hyperemesis phase typically involve:
1. Intravenous (IV) Fluid Replacement: This is administered to combat dehydration, which is a common consequence of severe vomiting.
2. Antiemetic Medications: Medications that help reduce vomiting may be prescribed to alleviate the symptoms.
3. Pain Management: Pain medication can be administered to help individuals cope with abdominal discomfort and pain associated with CHS.
4. Proton-Pump Inhibitors: These are used to treat stomach inflammation, which is often seen in individuals with CHS.
5. Hot Showers: Frequent hot showers have been found to provide some relief from the symptoms. Many individuals with CHS engage in compulsive showering, which can help alleviate nausea and discomfort.
6. Benzodiazepines: These medications may be prescribed to help individuals manage anxiety during this challenging phase.
Additionally, there is some evidence to suggest that the application of capsaicin cream to the abdominal area can help decrease pain and nausea, potentially offering another avenue for symptom relief. The active ingredients in capsaicin cream produce effects similar to those experienced with hot showers.

It’s important to note that the symptoms of CHS often improve within a day or two unless an individual continues to use marijuana during this time. To achieve a full recovery and prevent symptom recurrence, it is imperative to discontinue marijuana use completely. Some individuals may find assistance through drug rehabilitation programs aimed at helping them quit marijuana use. Therapeutic approaches, such as cognitive behavioral therapy or family therapy, can also play a valuable role in the recovery process by providing support and addressing potential underlying factors. Ceasing marijuana use is essential to achieving sustained relief from CHS symptoms, and once individuals discontinue marijuana consumption, their symptoms typically do not return, allowing them to regain their health and well-being.
