What Kinds of Allergic Reactions to Marijuana Are There?

Marijuana allergies are characterized by a rash, itchy eyes, runny nose and sneezing. Unlike seasonal pollen allergies, marijuana allergic reactions have a more sudden onset. However, many allergic responses to cannabis have been incorrectly labeled over time owing to the stigma surrounding cannabis. Since the early 1900s, when cannabis and hemp were made illegal due to misunderstanding, fear, and corporate interests, there has always been a lack of research and open-mindedness towards cannabis.

Since the demonization period throughout the 1900s and into the present day, cannabis and hemp have both made tremendous progress in society acceptance. There is still a long way to go before we truly comprehend this plant in all its forms, and we’ve only just begun breaking down the stigma barriers. Since devoting more attention to researching cannabis in greater depth, we’ve noticed that some of the so-called marijuana allergy symptoms were confused with cannabinoid effects.

However, there are still individuals who experience symptoms of marijuana skin rashes, negative reactions to indicas and sativas, or a variety of allergic responses to cannabis.


An allergy to marijuana, also known as a marijuana sensitivity, is caused by cross-reactivity with other allergens. The primary dangers associated with a marijuana allergy include the possibility of it being linked to cross-reactivity with other allergens.

Cross-reactivity occurs when the proteins in the marijuana plant, such as pollen, resemble those found in another plant. When a person comes into contact with similar proteins elsewhere, an allergic reaction may develop.

Foods with proteins that resemble marijuana proteins, and which may, therefore, cause an allergic reaction in people with marijuana allergies, include:

  • almonds
  • apples
  • bananas
  • chestnuts
  • eggplant
  • grapefruit
  • peaches
  • tomatoes


Marijuana allergies are diagnosed in the same way as other types of allergies using skin tests or blood testing.

Skin Tests

A medical history will be taken, as well as a physical examination. They may also utilize a skin prick test. This test isn’t particularly invasive and provides results in a matter of minutes.

The doctor will apply a diluted allergen, such as marijuana, to the skin’s surface with a needle in a skin prick test. Within 15 minutes, if a red bump or wheal, itching, and redness appear in that region, the individual may be allergic to it.

An intradermal test may also be used. This procedure involves using a small needle to insert a diluted allergen just beneath the skin’s surface.

Blood Tests

Another method of detecting marijuana allergies is through blood tests. Antibodies to marijuana are detected in a sample of blood. If there are more antibodies in the blood than normal, they’re more likely to be allergic to cannabis.

In certain circumstances, blood tests are superior to skin prick tests since they only require a single needle pricks. They’re also less likely to be influenced by other medicines. The results, on the other hand, take longer to return, and the tests are more expensive than skin testing.


If you believe you have an allergy to marijuana, the best course of action is to avoid it entirely. This includes any form of contact, including smoking, touching, eating, and exposure to the environment.

If you’ve been using marijuana to treat a medical condition, you should first speak with your doctor and get professional medical advice. They may be able to provide other treatment choices for your problem.

On occasion, you may be unable to avoid airborne cannabis exposure. This is frequently true for persons who live with or work in the cannabis sector. If that’s the situation, talk to your doctor about allergy treatment options.

Nasal decongestants and antihistamines are common treatments. They may advise you to use a nasal spray or other medicines to relieve symptoms such as a stuffy nose and red eyes. To avoid exposure, they may advocate using a respirator or face mask.

If you have a severe allergic reaction to marijuana, you’ll need to carry an Epi-pen around at all times. This medicine works fast to cure serious symptoms like breathing difficulties and a drop in heart rate. To be safe, some people may require multiple Epi-pens.
