With marijuana use becoming more and more normal — and also authorized for either medical or even recreational use in an increasing number of states — doctors are warning about a little-known health risk: It is possible to end up being hypersensitive to weed.

The writers of a fresh research declare it is a problem we’re able to begin to see more regularly. Their investigation, publicized this week within the journal Annals of Allergy, Asthma and Immunology, put together the healthcare evidence documenting cases of allergic reactions to the marijuana plant, commonly known by its Latin name Marijuana sativa. “Even though nonetheless comparatively unheard of,” they produce, “allergic disease connected with C sativa exposure and use has been reported with increased frequency.”

Similar to most plant allergens, they note, pot pollen might cause symptoms just like allergic rhinitis — irritation of the sinus passages accompanied by sneezing, congestion, itching and also a runny nose — together with eye inflammation and asthma.

The authors, allergy and immunology professionals Dr. Thad Ocampo and Dr. Tonya Rans, state that in people with allergies, simply touching the plant might cause skin reactions including hives, itching and puffiness or swelling around the eyes.

Exposure to pot smoke can also trigger symptoms such as nasal congestion, sneezing, coughing, wheezing, bloodshot eyes plus an itchy throat.

An additional potential allergy risk derives from ingesting edible weed goods. One patient mentioned within the investigation suffered a serious reaction after consuming hemp seed-encrusted seafood and also needed antihistamines and a shot of epinephrine, an urgent situation treatment for potentially life-threatening allergy symptoms which includes anaphylaxis. Later tests demonstrated the individual was not allergic to seafood — hemp seeds in the pot plant were to blame.

Even in people that don’t use medical marijuana themselves, more predominant and also open growth of the plant may lead to allergy problems. Marijuana pollen, that generally sheds in late summer and also early autumn, is “very buoyant, making it possible for distribution across many miles,” the analysis claims.

The study urged doctors to be familiar with marijuana as a possible source of allergy symptoms when making an analysis. The creators note that as pot becomes 100 % legal in more places, “cannabis might become an ever more relevant ‘weed’ for the allergist.”

What advice do they have for patients which might be sensitive to medical marijuana? In a nutshell, just decline. “As with other allergens, avoidance is usually recommended,” they write.

A person who does develop allergy symptoms from marijuana might be assisted by treatment with antihistamines, intranasal steroids or nasal decongestants, they said. People that have a history of anaphylaxis, a severe whole-body allergic reaction that may include breathlessness or maybe swallowing, were urged to keep a prescription epinephrine injector, like an EpiPen, on hand.
