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 oil or whether CBD can provide treatment or relief for other types of allergic reactions.
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.
CBD oil overview
A 2011 research report published in the journal Free Radical Biology and Medicine examined the potential role of CBD in various inflammatory-type conditions. George W. Booz, a professor in the department of pharmacology and toxicology at the University of Mississippi Medical Center, concluded 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 … .”
“You can have a cross-reaction with certain foods that share certain antigens, certain components, with the cannabis plant itself,” Silvers said.

Because CBD supplements come in so many different forms—such as oils, gummies, tinctures, and vapors—the amount that’s actually absorbed can vary drastically. This, combined with each person, will ultimately affect which (if any) CBD side effects you might experience.
Some common side effects when using CBD include drowsiness and sedation. This is also considered a benefit, but Dr. Jas Matharu-Daley, a physician and chief medical officer for a CBD brand, notes that the effects might be too strong if you’re also taking CBD with other sedating medications.
Can Interact With Other Medications
The most comment side effects of CBD include drowsiness, gastrointestinal issues, dry mouth, reduced appetite, nausea, and interaction with other medications. Those are outlined in detail below.

“CBD is not an intoxicating substance, whereas THC is a psychoactive that can get you high,” explains Dr. Jas Matharu-Daley, a physician and consultant for a brand that specializes in CBD production.
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. Some common allergic reaction symptoms to CBD oils are:
Difficulty breathing, shortness of breath, or wheezing
Is It Possible To Have An Allergy To CBD?
Although rare, anaphylactic shock is a life-threatening allergic reaction that can be caused by an allergic reaction to CBD oil. When someone is experiencing anaphylactic shock, their body is flooded with chemicals that cause their airways to narrow and restrict breathing. If the following symptoms are being exhibited, it is strongly advised to seek medical attention immediately:
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.
There are a handful of side effects that some people might experience from using CBD oil. These side effects are not considered allergic reactions to CBD, but might be caused by using too much CBD at once or due to a sensitivity to CBD. Some common side effects of utilizing CBD oils are:
