Cannabinoid hyperemesis syndrome (CHS) is a rare illness associated with the use of cannabis. It was first described in medical literature in 2004 and has since gained recognition as a distinct condition. CHS is characterized by recurrent episodes of severe vomiting, abdominal pain, and nausea in individuals who frequently use cannabis.

Definition and symptoms of CHS

CHS is defined by the triad of symptoms: severe cyclic vomiting, abdominal pain, and relief with hot showers or baths. The vomiting episodes are often intractable and can last for hours or even days. Patients typically report a pattern of using cannabis heavily for months or years before the onset of symptoms.

Prevalence and incidence rates

Due to the limited understanding of CHS and the lack of specific diagnostic criteria, accurate prevalence and incidence rates are challenging to determine. However, it is believed that CHS is relatively rare, but its prevalence may be increasing as cannabis use becomes more widespread.

Diagnostic challenges

One of the key challenges in diagnosing CHS is the lack of a specific diagnostic code in the International Classification of Diseases, Tenth Revision (ICD-10). Without a designated code, it is difficult to accurately capture the number of cases and conduct comprehensive research on the condition. The absence of a specific code also leads to underrecognition of CHS by healthcare professionals, further exacerbating diagnostic challenges.


Cannabinoid Hyperemesis Syndrome

To gather data on CHS, researchers conducted a chart review process in a Michigan hospital. This involved systematically reviewing the medical records of patients to identify cases of CHS and collect relevant information.

Inclusion criteria

The researchers established specific inclusion criteria to ensure that the identified cases were consistent with the diagnosis of CHS. These criteria typically included a history of heavy cannabis use, recurrent episodes of severe vomiting, and relief with hot showers or baths. Additional criteria may have been applied to ensure the accuracy and reliability of the data.

Data collection and analysis

Once the cases of CHS were identified, data was collected from the medical records of the patients. This included demographic information, clinical presentation, medical history, and treatment interventions. The collected data was then analyzed to identify any patterns or trends that could contribute to a better understanding of CHS.


The chart review process identified a total of 275 patients with CHS in the Michigan hospital. Among these patients, there was a diverse range of demographic characteristics, including age, gender, and ethnicity. The most common clinical presentation of CHS included severe cyclic vomiting, abdominal pain, and the unique feature of finding relief in hot showers or baths.

Etiology and Pathophysiology

The exact mechanisms of CHS are not yet fully understood. However, it is believed that the interaction of cannabinoids with receptors in the digestive system plays a role in the development of CHS.

Effects of cannabinoids on the digestive system

Cannabinoids, the active compounds in cannabis, can bind to cannabinoid receptors located in the gastrointestinal tract. This interaction can impact the normal functioning of the digestive system, leading to symptoms such as nausea and vomiting.

Proposed mechanisms of CHS development

There are several proposed mechanisms for the development of CHS. One theory suggests that prolonged exposure to cannabinoids may disrupt the normal regulatory mechanisms in the digestive system, leading to dysregulation and the onset of symptoms. Another theory suggests that a buildup of cannabinoids in the body may trigger a hypersensitivity reaction, resulting in the characteristic symptoms of CHS.

Association with Marijuana Legalization

The legalization of marijuana in Michigan has had significant implications for the prevalence of CHS in the state.

Impact of marijuana legalization in Michigan

With the legalization of recreational marijuana, there has been a notable increase in cannabis use across the state. This increase in use has raised concerns about the potential consequences, including the development of CHS.

Increase in CHS cases after legalization

Following marijuana legalization, the number of CHS cases in the Michigan hospital reviewed by researchers showed a significant upward trend. This suggests a potential association between increased cannabis use and the occurrence of CHS.

Comparison to pre-legalization period

Comparing the incidence of CHS before and after marijuana legalization further supports the link between increased cannabis use and the development of CHS. The data from the chart review provides valuable insights into this association and highlights the need for continued research on the impact of marijuana legalization on public health.

Diagnostic Challenges and Need for an ICD-10 Code

The absence of a specific ICD-10 code for CHS presents significant diagnostic challenges and impedes proper research and understanding of the condition.

Current diagnostic criteria for CHS

Currently, the diagnosis of CHS relies on clinical criteria and the exclusion of other potential causes for the symptoms. This subjective approach can lead to misdiagnosis and delays in appropriate management. A standard, universally accepted set of diagnostic criteria would greatly enhance accurate identification and diagnosis of CHS.

Limitations of the ICD-10 coding system

The ICD-10 coding system serves as a global standard for clinical diagnoses, but its limitations become apparent in cases like CHS. The lack of a specific code for CHS hinders accurate reporting and tracking of cases, making it difficult to estimate its true prevalence and fully investigate the condition.

Importance of accurate diagnosis for research and treatment

The development of a specific diagnostic code for CHS is crucial for advancing research and improving patient care. Accurate diagnosis is essential for conducting epidemiological studies, determining appropriate treatment strategies, and raising awareness among healthcare professionals and the general public.

Management and Treatment

The management and treatment of CHS involve both non-pharmacological interventions and pharmacological options.

Non-pharmacological interventions

One of the most effective non-pharmacological interventions for CHS is the use of hot showers or baths for symptom relief. The heat helps alleviate the symptoms and provides temporary relief during episodes of severe vomiting and abdominal pain. Adequate hydration and rest are also essential in managing CHS.

Pharmacological treatment options

Pharmacological treatments for CHS focus on alleviating symptoms and preventing vomiting. Antiemetic medications, such as ondansetron or prochlorperazine, may be prescribed to manage acute episodes. In some cases, benzodiazepines like lorazepam have been used to provide symptomatic relief and reduce anxiety.

Prognosis and long-term outcomes

The long-term prognosis of CHS is generally good once the individual stops or significantly reduces cannabis use. With abstinence, the recurrent episodes of vomiting and abdominal pain typically cease, and the individual can return to a normal quality of life. However, it is essential for individuals with CHS to be aware of the potential risks of continued cannabis use and to seek appropriate medical advice.

Education and Awareness for Healthcare Professionals

Healthcare professionals play a crucial role in recognizing and managing CHS. Increased education and awareness are essential in ensuring accurate identification and timely intervention.

Importance of recognizing CHS symptoms

It is vital for healthcare professionals to be knowledgeable about the symptoms and key features of CHS to differentiate it from other gastrointestinal conditions. Early recognition can prevent unnecessary investigations, misdiagnosis, and delays in appropriate management.

Providing accurate information to cannabis users

Healthcare professionals should provide accurate and evidence-based information to cannabis users regarding the potential risks of excessive cannabis use, including the development of CHS. Open and non-judgmental communication is key to fostering trust and ensuring that individuals have the necessary information to make informed decisions about their health.

Screening and prevention strategies

Implementing screening and prevention strategies is essential in identifying individuals at risk for CHS and preventing the development or progression of the syndrome. Integrating screening questions about cannabis use into routine medical assessments can help identify individuals who may be at risk and provide appropriate education and intervention.

Public Health Implications

The growing problem of CHS has significant public health implications that need to be addressed.

Addressing the growing problem of CHS

As the prevalence of cannabis use continues to rise, so does the risk of CHS. Healthcare systems, policymakers, and public health organizations need to develop comprehensive strategies to address and mitigate the negative impacts of CHS on individuals and communities.
