Signs of a marijuana allergy are very similar to any other kind of allergy, according to Dr. Rachna Patel. “It could include things like sore or itchy throat, stuffy nose, coughing, wheezing, shortness of breath, swelling, red and teary eyes, rash, hives, bronchitis, and asthma,” explained the cannabis expert. Contact dermatitis caused by touching weed can manifest in blisters, hives, itchiness, and inflamed skin, per Medical News Today.
If you have asthma, smoking weed or becoming exposed to it in some other way could trigger a flare-up, per Allergy Asthma Network. “Asthma may be related to occupational exposure, while anaphylactic reactions can often occur from hempseed exposure,” shared an allergist and professor of medicine at the University of Toronto, Canada, Dr. Gordon L. Sussman (via Forbes). Occupational exposure refers to being exposed to cannabis or any of its properties as a result of your work.
More serious signs of an allergic reaction include anaphylaxis, which is life-threatening. You might find it difficult to breathe and feel dizzy if you’re experiencing a severe reaction to cannabis. Other symptoms of anaphylaxis include vomiting, flushed or pale skin, swelling in the mouth and throat, a quickened pulse, and a drop in blood pressure, per Medical News Today.
