How to Know If You Are Allergic to CBD

Published on

As interest in CBD-rich products grows worldwide, many people are enjoying the medical benefits of cannabidiol (CBD) without experiencing any euphoric effects or feeling stoned.” However, should they worry about developing a marijuana allergy? Every drug has risks, so even if you had no problem with marijuana in the past, you could develop symptoms with repeated use.

You could be allergic to marijuana in all forms, which can cause various problems for health and well-being. The allergy is specifically caused by the chemistry of the cannabis plant’s enzymes, which produces reactions in select individuals. There has been an increase in the number of marijuana allergies reported. Keep in mind that allergic reactions are unique to individuals, so your symptoms or reaction time might be entirely different from that of someone else who came in contact with the allergen. However, if you experience any or all of the following symptoms after using marijuana, there is a good chance that you have a hypersensitivity response. 

Upper Respiratory Symptoms

Marijuana flowers produce pollen, which can cause upper respiratory issues for people who have a sensitivity. An allergen such as weed can cause nasal congestion, which can lead to headaches, as well as post-nasal drip, sore throat and sneezing. The most common symptoms are similar to seasonal allergies but exposure to marijuana in any form can cause difficulty breathing and even bring on asthma attacks. 

Skin Irritation

A marijuana allergy can have negative consequences for skin, from constant itching to rashes or hives. The dermatological symptoms of an allergic reaction can resemble contact dermatitis. Other key indicators include redness, blisters and dry, scaly skin.

Problems With Your Eyes

You may experience itchy, bloodshot and watery eyes if you are allergic to marijuana. In a 2007 study, scientists found that a 28-year-old man who smoked marijuana experienced, among other symptoms, watery eyes and eye redness.

Disordered Mood

When you are allergic to cannabis, it can affect your mood — and not in the way you intended! It can cause irritability and chronic fatigue, not to mention migraines. Of course, this can become a vicious cycle, with all of the symptoms making you even more uncomfortable. 


Although it isn’t common, a marijuana allergy could cause a severe reaction, anaphylaxis, which could lead to coma or death. Symptoms include difficulty breathing, dizziness, fainting, itchy and flushed or pale skin, low blood pressure, swollen tongue or throat, weak and rapid pulse, and vomiting. Obviously, you should go to the emergency room if you experience any of these symptoms.

There are many different ways to address these symptoms but as there is currently no treatment for a marijuana allergy, you should avoid using any CBD products. You should not smoke, eat or touch the plant to prevent your allergic reaction from worsening. You can manage symptoms with anything from an antihistamine to essential oils. For most with mild symptoms, minor irritations will soon go away. If your reaction is severe, you should promptly seek medical attention.
