Allergic Reaction To CBD Gummy

Can Someone Be Allergic To CBD? CBD is a plant-based compound, and allergies to plants are a real thing. But can you actually be allergic to CBD oil? Is it CBD or other hemp compounds that can trigger an allergic reaction? Learn about the potential for hemp allergy and allergic reactions to CBD oil. Discover whether CBD can help with allergies.

Can Someone Be Allergic To CBD?

Is It Possible To Have An Allergy To CBD?

With CBD oils and products becoming more popular and relevant, there have been more cases of people showing adverse symptoms to CBD. Some of these symptoms are considered side effects or sensitivity to CBD, while other symptoms are allergic reactions to CBD.

An allergic reaction can occur from any product the body sees as an allergen. The most common allergies occur from foods, medications, insect stings, pollen, and pet dander. Since CBD is derived from the cannabis plant called hemp, CBD contains properties like pollen and histamine that can cause allergic reactions. Although allergies to CBD are rare, it is possible for people to be allergic to CBD. CBD has also been known to help with allergies due to the antihistamine and anti-allergenic properties.

An allergic reaction to CBD oil can range from an itchy nose to breathing problems. It is important to stop using CBD at the first sign of any negative side effects from CBD. To understand the difference between being allergic to CBD or exhibiting side effects from CBD, it is important to understand the different symptoms of both.

What happens if I’m allergic to CBD?

According to the American Academy of Allergy, Asthma, and Immunology, someone with allergies to CBD can exhibit symptoms after inhaling, touching, smoking, or consuming any products containing CBD. An allergic reaction happens when the body’s immune system overreacts to a substance that the body sees as a threat. To protect the body, the immune system will produce antibodies called Immunoglobulin E, which cause the symptoms of an allergic reaction. These reactions vary depending on the person’s immune system and the number of Immunoglobulin E their body releases. An allergic reaction does not always occur on the first exposure to the allergen and allergies can change over time.

Since CBD is extracted from hemp plants, most allergic reactions to CBD are similar to seasonal allergies or allergies to pollen and fungi. These symptoms should go away if you stop using CBD.

CBD Allergies: Can You Have Allergic Reaction to CBD Oil (Itching & Rash)?

Allergies are adverse reactions of the immune system that are not triggered in healthy people. Symptoms of allergies include sniffling, watery eyes, itching, or asthma.

According to official statistics, allergies are the No. 6 cause of chronic illnesses in the United States. Hay fever affects roughly 19.9 adults, as reported in 2017 by the Centers for Disease Control and Prevention.

CBD is a phytochemical. In other words, it comes from plants — specifically, from cannabis plants.

Given this, it’s natural to wonder whether CBD oil, a product that contains over 400 phytochemicals aside from CBD, can trigger allergies.

Though there’s not much research regarding allergic reactions to CBD oil, the cannabis plant itself has been linked to allergies.

Today, we’ll elaborate on potential allergies to CBD oil, why they happen, what researchers are saying, and whether you can still use CBD if the full-spectrum oil causes you to experience the aforementioned pesky symptoms.

Allergies in the United States in Numbers

Over 50% of the U.S. population has allergies to at least one thing. Hay fever — allergic rhinitis — is the most common allergy, affecting between 10 and 30% of all American adults, and may affect up to 40% of children.

While there’s no cure for allergies, they can be effectively managed with proper nutrition, supplementation, and a healthy lifestyle. Of course, avoiding triggers is also a good strategy.

Some allergies are more severe than others and may require a complex treatment

Below we break down the mechanism of allergies.

A Brief Overview of Allergies and How They Work

Allergies are a common health problem. They manifest in itching, sneezing, a runny nose, droopy eyes, and sometimes difficulty breathing.

But what is the root of allergies? Where do they start?

The answer is: A compromised immune system.

The immune system controls allergic reactions. A properly functioning immune system can tell the difference between harmful and safe compounds to eliminate potential dangers. However, when it goes out of whack, it starts to identify benign substances as potential dangers — creating antibodies to attack these “irritants.”

In fact, the body releases antibodies every time a person is exposed to the allergen.

Histamine is the antibody with plant allergies like hay fever. The antihistamine medications work to prevent antibodies from causing damage to the immune system. Common antihistamine drugs include Claritin, which is available over the counter. CBD allergies fall into the category of plant allergies.

Food allergies are more difficult to treat. The immune system becomes aggressive against proteins in the food, triggering serious symptoms like anaphylaxis.

Anaphylaxis can be fatal if left without immediate help. Sufferers usually carry special pens with epinephrine to treat an allergic reaction once it begins.

In a 2009 study published in Immunobiology, the authors suggested that cannabinoids such as CBD and THC could take part in immunosuppressive processes (1). This means that they may block the reactions of the immune system against the triggers.

Does it mean you could use CBD oil for allergies directly as well as for preventative measures?

Not exactly, but we’ll get to that later on.

Some people are worried that CBD might cause allergies. Is this claim backed by any scientific evidence, or is it just a rumor?

Can You Be Allergic to CBD?

An allergy to cannabis is a real thing. By the same token, a person might be allergic to CBD. Inhaling, eating, or touching cannabis plants can cause allergic reactions due to contact with pollen. When you inhale that pollen, you may suffer from hay fever.

In a 2018 study, the research team found that people with allergies to mold, dust mites, cat dander, and plants, have a higher risk of developing an allergy to cannabis (2). However, this is the only study regarding this subject as of today. More research is needed to establish a clear link between cannabis and allergic reactions.

Since it’s possible to be allergic to cannabis if you’re allergic to pollen or mold, contaminants in CBD products should be the main concern for you.

When it comes to cannabinoids, things look quite similar. A 1971 study found that THC could produce an allergic reaction (3). CBD and THC have similar chemical structures, meaning that CBD also has the potential to trigger an allergy. However, it’s important to note that the side effects of CBD are different from allergic reactions. The study also didn’t focus specifically on CBD.

Common Allergic Reactions to CBD Oil

A CBD allergy can show up in a variety of ways. Two people may have completely different symptoms, so it can be tricky to distinguish between a CBD allergy from the mild side effects of CBD.

Potential adverse reactions to CBD include dizziness, dry mouth, lethargy, nausea, and diarrhea. These are not the symptoms of an allergy to CBD. Moreover, they are nearly nonexistent in normal doses.

CBD oil allergies have the following effects:

  • Dry, Itchy, or Red Eyes: Although this side effect is associated with taking THC due to its ability to dilate blood vessels in the eyes, some users might experience this after taking CBD oil. If you have this kind of reaction, or your eyes are watering, it might be the symptom of a CBD allergy.
  • Breathing Difficulty: If you have difficulty breathing, seek immediate medical attention. With CBD products, this side effect may stem from poor-quality products that contain dangerous additives or mold.
  • Skin Irritations: when you use CBD topically, you may notice a rash or hives as the manifestation of your allergy to CBD. However, this could also be triggered by one of the many other ingredients in creams and gels, so make sure to read the list of ingredients carefully.
  • Migraines: While some CBD users may experience a slight headache at higher doses, migraines are a severe symptom that can indicate an allergy to some of the compounds in CBD oil.

People who are allergic to CBD oil are advised to try CBD isolate instead of full-spectrum products. Full-spectrum CBD oils are made using the whole plant, so they contain cannabinoids, terpenes, flavonoids, essential oils, proteins, vitamins, trace minerals, and plant wax. As a result, there’s a higher risk of experiencing an allergic reaction.

It’s a good idea to try a few different CBD products with various spectra to determine which form of CBD works without triggering allergies. You should also check with a doctor to seek medical advice about what to do when the symptoms kick in.

Research on CBD Oil & Allergies

  • Researchers from the Duke University School of Medicine found that about 20% of the 100 people they tested experienced allergic reactions to linalool, while 8% were allergic to limonene (4). These two molecules are commonly found in cannabis extracts such as CBD oil.
  • In a letter entitled “Marijuana and stoned fruit,” written by doctors from the University of California, San Diego, and published in the Annals of Allergy, Asthma, and Immunology, a 24-year-old male marijuana daily user had an anaphylactic reaction after eating yogurt with hemp seeds (5).
  • A 2013 study from the Internal Archives of Allergy and Immunology examined 21 patients with food allergies for reactivity to cannabis lipid transfer proteins (LTP), which are alleged allergens (6). Twelve subjects were allergic to cannabis, and all 12 had more severe symptoms of food allergy than those who weren’t allergic to cannabis.

Can CBD Oil Help with Allergies?

1While research supporting the idea that CBD could alleviate allergies and their symptoms are limited, there are some studies regarding its general effects on inflammation, which is one of the body’s triggers of an allergic reaction.

In a 2011 research report published in the journal Free Radical Biology and Medicine, the authors investigated the potential impact of CBD on various inflammatory conditions (7). George W. Booz, a professor in the department of pharmacology and toxicology at the University of Mississippi Medical Center, suggested in the report:

“Inflammation and oxidative stress are intimately involved in the genesis of many human diseases. Unraveling that relationship therapeutically has proven challenging, in part because inflammation and oxidative stress feed off each other. However, CBD would seem to be a promising starting point for further drug development given its antioxidant (although relatively modest) and anti-inflammatory actions on immune cells.”

According to the research team, there is no clinical evidence CBD oil could alleviate allergies, so while we have some laboratory studies suggesting anti-inflammatory effects exist, we need more longitudinal research to draw definitive conclusions.

Final Thoughts on CBD Allergies

If you want to minimize the risk of experiencing an allergic reaction to CBD, it’s best to purchase from a reputable brand that sells high-quality products. A lot of allergies caused by CBD oils appear to stem from unwanted substances such as contaminants, solvents, or plant residue. Always make sure to check for third-party lab reports when browsing different CBD products. It might be worth spending some extra time to ensure you get a decent product.

Right now, research on CBD allergies is in the early stage. As the number of CBD users grows, so will the data about potential allergic reactions. An allergy to CBD is extremely rare, but people with pre-existing allergies or other health conditions should take particular caution.

Can you have an allergic reaction to CBD?

Whether it’s sniffling, watery eyes, itching, or asthma, many of us are all too familiar with symptoms of allergies.

According to the Asthma and Allergy Foundation of America, allergies are the sixth leading cause of chronic illness in the US. There were 19.2 million adults diagnosed with hay fever in 2021, according to the Centers for Disease Control and Prevention (CDC). It is estimated that 32 million Americans live with food allergies; more than 170 foods may lead to an allergic reaction.

Considering the increasing awareness and use of cannabidiol (CBD) and the existing potential for pollen and food allergies, allergy sufferers may wonder whether they are at risk for an allergic reaction to CBD or whether it can provide treatment or relief for other types of allergic reactions.

Though there’s not much in the way of allergy research specifically for CBD at this point, the cannabis plant itself has been linked to allergic reactions.

“Marijuana is a plant and produces pollen and one can become allergic to the pollen and the plant, especially if one has pre-existing allergic tendencies,” said Dr. William S. Silvers, clinical professor of medicine in allergy and immunology at the University of Colorado School of Medicine.

That being said, only male marijuana plants produce pollen, and they are exceedingly rare in cannabis and hemp production because they produce less oil and CBD than female plants. Therefore, a consumer’s exposure to pollen would be extremely rare.

CBD overview

CBD is the second-most-prominent cannabinoid derived from the cannabis plant, after the intoxicating cannabinoid tetrahydrocannabinol (THC). CBD, extracted from marijuana or industrial hemp, has gained popularity for its potential benefits for a number of conditions, including inflammation, arthritic pain, depression, seizures, and anxiety.

Allergies in the body

A properly functioning immune system works to protect the body from pathogens such as bacteria, viruses, and fungi, and attack these unwanted microorganisms in order to help prevent disease. In the case of allergies, the immune system triggers a reaction to plant pollen and other harmless substances in the environment. The result, depending on the type of allergy, can be a variety of symptoms, including itchy eyes, runny nose, asthma, hives, skin itching, or more severe reactions such as anaphylaxis, which can be life-threatening.

Allergic reactions to CBD

Humans commonly experience allergic reactions to many kinds of plant pollen. However, only male cannabis plants produce pollen, whereas female plants are more widely used for oil and cannabinoid production. Large-scale industrial hemp fields may include a variety of mature males (pollen) as well as fertilized females (oil and seeds). The impact of hemp pollen on everyday consumers, as well as the communities that work and live near these production facilities, has not been studied.

People can also develop allergies to some of the terpenes found in cannabis. For instance, researchers from the Duke University School of Medicine found that about 20% of the 100 people they tested had an allergic skin reaction to linalool, whereas 8% had reactions to limonene. These kinds of contact allergies may not be common in the general population, but anyone with these allergies working in the cannabis production industry could have health consequences.

Dr. Gordon Sussman, an allergist in Canada and professor at the University of Toronto, said there is very little published research on CBD allergies. “It’s an unknown area at this point,” he said. “But we know that cannabis sativa is an allergen and we know that it’s a common allergen.”

Humans commonly experience allergic reactions to many kinds of plant pollen. Only male cannabis plants produce pollen. Most cannabis products, including CBD oil, are made using female plants.

He said that cannabis allergies, like other forms of allergies, can worsen as exposure to the allergen continues. Most people with cannabis allergies suffer from a runny and stuffy nose (rhinitis), eye irritation (conjunctivitis), and sometimes wheezing, Sussman explained. But there have been cases of more severe reactions such as anaphylaxis, which have primarily resulted from ingestion of hemp seeds.

According to a letter entitled “Marijuana and stoned fruit,” written by doctors from the University of California, San Diego, and published in the Annals of Allergy, Asthma, and Immunology in 2018, a 24-year-old man who smoked marijuana daily visited their allergy clinic two weeks following an anaphylactic reaction after eating yogurt with hemp seeds.

“This was his first known ingestion of hemp seeds. Immediately after consumption, he developed oral pruritus [itching] that progressed to shortness of breath, facial swelling, and pre-syncope [sensation prior to fainting],” the letter stated.

Those with food allergies may also be susceptible to cross-reactivity.

“You can have a cross-reaction with certain foods that share certain antigens, certain components, with the cannabis plant itself,” Silvers said.

Such foods may include tomatoes and fruits containing pits, such as peaches, he said. It’s a similar cross-reactivity to what is seen in people with ragweed allergies who might experience symptoms such as itchy mouth if they eat fruit in the melon family, he added.

“The same thing goes with cannabis and tomatoes and peaches and almonds and a number of other foods … eggplant, grapefruit, apples,” Silvers said.

He also noted that the type of allergic reaction depends on the type of exposure. In addition to cannabis pollen allergies and food-based allergies, skin allergies are also a possibility. “Touching the plant can very easily lead to dermatitis, itching, and skin reactions,” he said.

Can CBD help with allergies?

While there isn’t much research supporting the idea that CBD can help the discomfort associated with common allergy symptoms, there is some research related to its general effects on inflammation, which is part of the body’s allergic reaction process. A study published in the Journal of Pharmacology and Experimental Therapeutics in 2018 showed that CBD was effective in reducing inflammation associated with allergic contact dermatitis in a lab model using human cells.

According to Silvers, there is no clinical evidence that CBD products can treat allergies. While there is experimental laboratory research suggesting anti-inflammatory effects exist, there’s no clinical patient substantiation.
