Can Cannabis Cause Vomiting? Understanding CHS Risks

Cannabis has become a mainstream part of many people’s lives, whether for recreational enjoyment, medicinal purposes, or simply as part of a lifestyle. It’s a versatile plant known for its many benefits, from pain relief to reducing anxiety and improving appetite. However, despite its growing popularity, cannabis isn't without its potential drawbacks, and one of the more serious, yet lesser-known, side effects that has come to light in recent years is Cannabinoid Hyperemesis Syndrome (CHS).

Q: Does weed make you puke?

A: In most cases, cannabis does not make you puke and is often used to reduce nausea. However, in rare instances, some long-term users may develop a condition called Cannabinoid Hyperemesis Syndrome (CHS), which can cause severe vomiting. If you experience frequent nausea or vomiting after using cannabis, it’s important to stop using it and consult a healthcare provider.

In this article, we'll dive deep into the phenomenon of CHS—what it is, how it develops, and why it happens. If you’re a long-term cannabis user, or if you’re just starting to explore the world of marijuana, understanding CHS is essential for making informed decisions about your consumption habits and health.

What is Cannabinoid Hyperemesis Syndrome (CHS)?

Cannabinoid Hyperemesis Syndrome (CHS) is a condition that causes frequent, severe episodes of nausea, vomiting, and abdominal pain in people who have been using cannabis heavily over an extended period. The condition is somewhat paradoxical because, for many people, cannabis is used to alleviate nausea and improve appetite. However, in individuals suffering from CHS, the body seems to respond in the opposite way, triggering symptoms of nausea and vomiting instead of relief.

CHS is rare but can be very distressing for those affected. It's typically seen in individuals who have been consuming cannabis regularly for years—often daily or nearly daily use. The severity of the symptoms can vary, but in many cases, the vomiting episodes can last for hours or even days, leading to dehydration, weight loss, and general discomfort.

Understanding the Symptoms of CHS

The hallmark symptoms of CHS are severe, recurrent vomiting and abdominal pain. These symptoms often worsen after cannabis use, which is why identifying the syndrome can sometimes be difficult. It can be easy to mistake the nausea and vomiting for a stomach bug or other gastrointestinal issue. However, CHS presents in a unique way and has a few tell-tale signs that set it apart:

Recurrent Vomiting: Episodes of vomiting can last for hours or even days and occur several times a month. These episodes are often not triggered by food or any other usual cause of nausea. Instead, they seem to be linked directly to cannabis consumption.
Abdominal Pain: Many individuals with CHS report experiencing severe abdominal discomfort, often in the upper abdomen. This pain can be cramp-like or constant and can add to the distress caused by the vomiting.
Compulsive Hot Showers or Baths: One of the more unusual features of CHS is that sufferers often find temporary relief from symptoms by taking long, hot showers or baths. While this may provide some comfort, the relief is typically short-lived, and the cycle of vomiting returns once the person stops using cannabis.
Dehydration: Due to prolonged vomiting, dehydration is a significant concern for people with CHS. Dehydration can lead to further complications, including weakness, dizziness, and even kidney problems if not addressed.
Periods of Relief: After an episode of vomiting subsides, people with CHS may feel completely fine for a time, only to have the cycle repeat itself later, often after consuming cannabis again. This on-and-off pattern is a key feature of the syndrome.

What Causes CHS?

The exact cause of CHS is not fully understood, but there are a few theories that explain why cannabis use could trigger such severe reactions in some individuals. One of the primary hypotheses is that long-term, heavy cannabis use disrupts the endocannabinoid system, which regulates many physiological processes, including nausea and appetite. THC, the psychoactive compound in cannabis, interacts with this system, and in some people, excessive or prolonged use may lead to an imbalance that triggers nausea and vomiting rather than alleviating it.

Additionally, it’s possible that cannabis use may lead to changes in the gastrointestinal tract, including delayed gastric emptying or other issues that disrupt the digestive process. Some studies suggest that the regular use of cannabis could alter the function of the stomach and intestines, causing symptoms like nausea and pain.

There is also some evidence suggesting that certain genetic factors may predispose some individuals to develop CHS. These genetic factors may influence how the body processes cannabis and could make certain people more susceptible to experiencing CHS after prolonged use.

How Cannabis Causes Vomiting: The Role of THC and the Endocannabinoid System

Cannabis has a complex relationship with the body’s endocannabinoid system, which regulates a variety of processes, including mood, appetite, pain, and nausea. The active compound in cannabis, THC, binds to cannabinoid receptors (CB1 and CB2) in the brain and throughout the body. These receptors are involved in regulating nausea, vomiting, and the digestive system, which is why cannabis has been used medicinally to combat nausea in cancer patients undergoing chemotherapy.

However, in some individuals who consume cannabis regularly and in large amounts, prolonged exposure to THC can cause dysregulation of the endocannabinoid system. This dysregulation can lead to paradoxical symptoms, such as vomiting and nausea. Essentially, instead of controlling nausea, cannabis starts to trigger it.

The exact mechanism is still unclear, but it is believed that chronic THC exposure desensitizes the cannabinoid receptors in the gut, altering normal digestive function. This could lead to nausea, delayed gastric emptying, and a variety of other symptoms commonly associated with CHS.

Risk Factors for Developing CHS

While anyone who uses cannabis regularly is potentially at risk for developing CHS, there are several factors that can increase the likelihood of this condition:

Chronic Cannabis Use: The primary risk factor for CHS is prolonged, heavy cannabis use, especially for those who use it daily or nearly every day for many years.
High-THC Cannabis: Those who consume high-potency cannabis, particularly concentrates or edibles with high THC content, may be more likely to develop CHS. High-THC cannabis may exacerbate the effects on the endocannabinoid system and increase the risk of vomiting and nausea.
Age and Gender: CHS is more commonly reported in younger adults, particularly men, although anyone can develop it. There may also be a genetic predisposition, which is still being explored by researchers.
Other Health Conditions: People with pre-existing gastrointestinal conditions, such as irritable bowel syndrome (IBS) or gastroesophageal reflux disease (GERD), may be more susceptible to developing CHS due to their already compromised digestive systems.

How Is CHS Diagnosed?

Diagnosing CHS can be challenging because its symptoms overlap with other gastrointestinal conditions, such as gastroenteritis or ulcers. However, a diagnosis is typically based on the following criteria:

Cannabis Use History: A history of long-term, heavy cannabis use is one of the primary clues.
Pattern of Symptoms: Recurrent vomiting and abdominal pain that seems to be linked to cannabis consumption, along with the relief found in hot showers, are key diagnostic signs.
Exclusion of Other Causes: Doctors will generally rule out other gastrointestinal conditions through tests and imaging studies before confirming CHS.

In some cases, patients may undergo blood tests, imaging, and even endoscopic procedures to eliminate other potential causes of nausea and vomiting.

How to Manage and Treat CHS

Currently, the only effective treatment for CHS is to stop using cannabis altogether. Once cannabis consumption is discontinued, the symptoms typically subside within a few days to a week. In the meantime, treatment focuses on managing the symptoms:

Hydration: Rehydrating the body is essential, especially after prolonged vomiting. This can be done through oral rehydration solutions or intravenous fluids in more severe cases.
Medications: Anti-nausea medications, such as ondansetron or metoclopramide, may be used to help control vomiting. Pain relief may also be prescribed if abdominal discomfort is significant.
Supportive Care: If dehydration or electrolyte imbalances are severe, a hospital stay for IV fluids and monitoring may be necessary.
Hot Showers: Although it’s not a permanent solution, many people find temporary relief by taking long, hot showers, a symptom unique to CHS.

Prevention of CHS

The most effective way to prevent CHS is to limit cannabis use or stop using it entirely. Those who experience symptoms of CHS should seek medical help and avoid using cannabis while they recover. If you are someone who enjoys cannabis but is concerned about CHS, it might be wise to moderate your consumption and opt for lower-THC products.

For those who choose to store cannabis for long periods, it’s important to consider how you store your products. Cannabis humidor boxes or a good weed storage box can help maintain the quality of your cannabis, ensuring it doesn’t degrade into something that might worsen your symptoms. Storing your cannabis in a stash box designed to keep the products fresh and sealed can make all the difference, particularly for those who want to limit exposure to high-THC strains.
