Causes of Weed Allergy

The most common cause of cannabis allergy is pollen. Most people are allergic to marijuana pollen and have severe reactions if they get in contact with it. It is because the weed plant releases a large number of anemophilous pollen, which can interact with human airways.

Since this pollen is transferred by wind, it can easily enter our nose or mouth. Doctors advise marijuana workers to wear a mask and gloves during work hours. You can also wear a full protective suit to avoid your skin getting in contact with the allergen.

Another reason could be that you are allergic to THC. It is the only psychoactive component in Marijuana and you can have a certain allergy to cannabinoids separately. Some people can also have a high sensitivity to this cannabinoid.

If a product has a high amount of THC or a user consumes more than the recommended amount of THC, it can cause hypersensitivity. Moreover, cannabis plants also contain the Cas s 3 protein, which can cause allergic reactions in some people.


Weed Allergy Diagnosis

Cannabis allergy is still a debated topic that is under research. However, a prick test is the most common way to test for allergies. During a prick test, a doctor will inject a small amount of allergen into your skin using a needle.

They will keep you under supervision to check for any reactions. If they notice physical or internal changes, they will put you on medication immediately. However, there is no standard test in the medical industry to identify surely if you have a weed allergy.

Doctors check your consumption history and how your body reacts after consuming minor doses. Skin testing is also a great way to find out contact allergies caused by weed exposure. This test provides better results than any other test.

Even though these tests are not standardized, they can inform you about the sensitivity in your body. You need to be careful while consuming any drug. So, make sure to start it in a small dose to see how your body reacts to it.


Weed Interactions

If you are on medication or have any other food allergies, you must consult your doctor before consuming weed. Marijuana can have a negative reaction when in contacts with drugs like sympathomimetics, anticholinergics, alcohol, and opioids.

Weed allergy can become more prominent if it interacts with other food allergens. Some common food allergens include nuts, tomatoes, grapefruit, peaches, bananas, apples, and eggplants. These foods have similar allergen properties as weed allergens, which can worsen the side effects.

Consuming these foods together with marihuana can also make you more sensitive to weed products, even if you don’t have an allergy. If you are physically exposed to these fruits due to your work, then the chances of nasal allergy are also high.

Go through the ingredient list at the back of your weed products to see if anything does not suit your diet restrictions. Moreover, if you have dust and pet dander allergies, the use of Marijuana can worsen the sensitivity.


What to Do if You are Allergic to Weed

The first thing to do if you get a reaction from marijuana consumption is to consult with a doctor. It can turn into a life-threatening problem if not taken care of properly. It is important to get an allergy test done to understand what is causing sensitivity.

Start with a minor dose and track your reaction to Marijuana. Once your doctor confirms the allergy, take allergy medication to wear down the reaction. You should avoid using marijuana-based products completely if you are allergic to their components.

However, you are medically advised to take Marijuana for a certain illness, consult with your doctor and take medication to minimize the reaction. Since there is no treatment for this allergy, the only way you can control it is by not exposing your system to marijuana allergens.

If you are an avid user of cannabis products and wondering how you can be allergic to marijuana all of a sudden, it means you are consuming low-quality products.

People also develop weed allergies after using it for several years. Therefore, make sure to use the highest quality product to ensure safety.
