Cannabinoid Hyperemesis Syndrome (CHS) is a paradoxical condition that has raised numerous questions in the medical and cannabis communities. A comprehensive understanding of this syndrome, including its causes, scientific background, and potential cannabinoid hyperemesis syndrome treatment is vital. In this blog post, we will also delve into a pertinent question often asked: Does CBD or CBD hemp flower usage lead to CHS?

What is Cannabinoid Hyperemesis Syndrome (CHS)?

CHS is a rare condition that occurs in some long-term users of THC-rich cannabis. It is characterized by cyclic episodes of debilitating nausea and vomiting. A person affected by CHS may also find unusual relief from these symptoms by taking hot showers or baths.

Contrary to the commonly known antiemetic properties of cannabinoids, CHS presents as an ironic reaction. Thus, creating a complex scenario for physicians and researchers.

Can CBD Cause CHS?

With CBD (Cannabidiol) gaining popularity for its therapeutic benefits, one might wonder, "Can CBD cause CHS?" or "Does CBD hemp flower contribute to the syndrome?"

The short answer is, it's uncertain. CBD, unlike THC, is not psychoactive and generally does not induce the same intoxicating effects. However, the existing literature does not conclusively link CBD to CHS. Most studies point towards THC, found in high amounts in Delta 9 and Delta 8 THC products, as the primary contributor.

Understanding the Science Behind CHS

The exact science behind CHS is not entirely clear. However, it is generally thought to stem from the long-term heavy use of cannabis products rich in THC, leading to a toxic buildup. Cannabinoid receptors, especially CB1 receptors located in the brain and the gut, are believed to be involved.

Overstimulation of these receptors may disrupt the normal functioning of the digestive system, leading to the symptoms experienced in CHS. Furthermore, a paradoxical reaction can occur, where the same cannabinoids that usually help with nausea and vomiting end up causing these symptoms.

The Phases

People with CHS often experience a sequence of three phases: the prodromal phase, the hyperemetic phase, and the recovery phase. The prodromal phase typically presents early symptoms of CHS like stomach discomfort and nausea, generally in the morning.

As the condition progresses, individuals enter the hyperemetic phase, characterized by intense bouts of cyclical vomiting, abdominal discomfort, and severe nausea. This phase is particularly distressing and may require the administration of IV fluids to prevent dehydration.

Treatment of Cannabinoid Hyperemesis Syndrome

The primary treatment for CHS is cessation of cannabis use. It is the most effective way to alleviate symptoms and prevent recurrence. However, the withdrawal process may be challenging for heavy users. In such cases, professional medical help should be sought.

In the acute phase, supportive treatments, such as intravenous fluid rehydration, antiemetics, and discomfort relievers may be beneficial. Interestingly, hot showers or baths also provide temporary symptom relief.

CHS and Diet: Foods to Avoid and Include

Now, let's focus on the crux of this blog - "Cannabinoid hyperemesis syndrome foods to avoid" and which foods to include if you have this syndrome.

While specific "trigger foods" for CHS aren't universally identified, certain general dietary recommendations can help manage symptoms. These are especially helpful during recovery, but it's important to remember that each person may respond differently.

Foods to Avoid (CHS Trigger Foods)

The following foods may exacerbate symptoms and are generally best avoided:

  1. Spicy Foods: These can irritate the digestive system and worsen nausea and vomiting.
  2. Fatty and Greasy Foods: High-fat foods can be difficult to digest and may increase discomfort.
  3. Alcohol and Caffeine: Both can irritate the stomach lining and increase nausea.
  4. High-Fiber Foods: While fiber is generally good for digestive health, in the acute phase of CHS, it might be harder for the body to digest, which could increase discomfort.
  5. Processed Foods: These may contain additives that can trigger gastrointestinal discomfort.

Foods to Include

On the other hand, certain foods and drinks can help soothe the digestive system and should be included in the diet:

  1. Ginger: This root has long been used as a remedy for nausea and vomiting.
  2. Peppermint: Whether as tea or infused in food, peppermint can help calm the stomach and reduce nausea.
  3. Hydrating Fluids: Dehydration is a real concern with CHS due to excessive vomiting. Drinking plenty of water, clear broths, or electrolyte-replenishing beverages can help.
  4. BRAT Diet: The BRAT diet stands for bananas, rice, applesauce, and toast. These bland foods are gentle on the stomach and can help ease symptoms during a CHS flare-up.
  5. Lean Proteins: Chicken, turkey, or tofu can be easier to digest than red meats or fatty proteins.


Cannabinoid Hyperemesis Syndrome is a perplexing condition, with many facets yet to be explored. While heavy THC consumption appears to be a main contributor, it's not entirely clear if CBD or CBD hemp flower can cause CHS.

Treatment generally involves abstaining from cannabis use and supportive measures to manage symptoms. A particular focus on diet, especially during recovery, can significantly aid in managing this syndrome. Avoiding potential trigger foods and including soothing, easy-to-digest options can help navigate this challenging condition.

Remember, it's crucial to seek professional medical advice if you or a loved one are experiencing symptoms of CHS. Navigating your way through this condition may feel daunting, but with proper guidance and lifestyle adjustments, it's manageable.

Can Cannabinoid Hyperemesis Syndrome (CHS) be caused by CBD?

The role of CBD in causing CHS is not definitively established. The condition is more commonly associated with long-term, heavy use of THC. However, due to the interaction of CBD with the endocannabinoid system, more research is needed to understand its potential link to CHS.

What foods should I avoid if I have Cannabinoid Hyperemesis Syndrome?

If you're dealing with CHS, it's advisable to avoid spicy foods, fatty and greasy foods, alcohol and caffeine, high-fiber foods, and processed foods. These can potentially trigger or exacerbate CHS symptoms.

What role does diet play in the treatment of CHS?

Dietary adjustments are an essential part of managing CHS, particularly during the recovery phase. Avoiding potential trigger foods and including soothing, easy-to-digest options can help alleviate symptoms and aid in recovery.

What is the primary treatment for CHS?

The mainstay of treatment for CHS is complete cessation of cannabis use. During severe episodes, supportive measures such as hydration with IV fluids, antiemetics, and discomfort relievers may be used. Dietary modifications can also play a significant role in managing this condition.
