A marijuana allergy, medically known as cannabis allergy, is an adverse immune response triggered by exposure to marijuana. For some individuals, inhaling or coming into contact with marijuana can lead to the onset of nasal or eye allergy symptoms. In rare instances, severe allergic reactions, like anaphylaxis, have been reported as a result of marijuana exposure. Notably, there has been a recent increase in the number of reported cases of marijuana allergy, highlighting the importance of understanding this condition. Furthermore, cannabis users may encounter a distinct condition called Cannabinoid Hyperemesis Syndrome (CHS). CHS is characterized by recurrent and severe episodes of vomiting and nausea, and it typically affects individuals who are long-term, daily users of marijuana. While CHS is a rare condition, it’s essential to exercise caution when using marijuana over extended periods.
According to the American Academy of Allergy, Asthma, and Immunology (AAAAI), it’s possible for an individual to develop an allergy or allergic sensitization to marijuana after their initial exposure to the plant. This exposure can occur through inhalation, smoking, physical contact, or even ingestion of marijuana. Notably, one of the primary concerns associated with a marijuana allergy is cross-reactivity with other allergens. Cross-reactivity happens when certain proteins within the marijuana plant share similarities with proteins found in other plants. When a person with a marijuana allergy comes into contact with these similar proteins elsewhere, it can trigger an allergic reaction. Some foods that contain proteins resembling those in marijuana include almonds, apples, bananas, chestnuts, eggplant, grapefruit, peaches, and tomatoes. If you have known allergies to any of these foods, it’s crucial to exercise caution when you are near marijuana plants or products. This awareness can help prevent potential allergic reactions and ensure your safety in environments where marijuana may be present.

Potential Risks of Marijuana Allergy
For those concerned about a potential marijuana allergy, it is advisable to consult a board-certified allergist to discuss their symptoms and receive professional guidance. The primary approach to managing a marijuana allergy is avoidance. If you suspect an allergy to marijuana, consider the following steps:
1. Avoid Exposure: It is essential to minimize exposure to marijuana in all its forms, whether it’s the plant’s pollen, mold from storage, or other triggers. This is particularly crucial for individuals with asthma, as inhaling marijuana smoke can exacerbate their symptoms.
2. Medication: Allergy and asthma medications, both prescription and over-the-counter, can play a significant role in preventing and alleviating symptoms resulting from exposure to marijuana. These medications may include albuterol inhalers and inhaled corticosteroids for asthma, as well as antihistamines, intranasal corticosteroids, and nasal decongestants for allergies.

3. Anaphylaxis: In cases where anaphylaxis, a severe and potentially life-threatening allergic reaction, is a concern, epinephrine auto-injectors should be readily available and used as the first-line treatment.
It’s worth noting that allergic reactions to marijuana can develop and intensify over time. In some instances, an allergy may not manifest during the initial exposure but can emerge upon subsequent encounters. While there are asthma and allergy medications available to manage symptoms, there is currently no standardized extract for marijuana skin tests or allergen immunotherapy. Individuals who cannot avoid marijuana due to their occupation, such as cannabis growers or law enforcement officers, should seek guidance from an allergist to explore strategies for minimizing their exposure and managing potential allergic reactions.
Marijuana Allergy Symptoms
Marijuana allergy symptoms encompass a spectrum of reactions, varying from mild to severe. These symptoms can manifest in different forms, impacting various parts of the body. The most common marijuana allergy symptoms include:
1. Asthma Symptoms: Individuals with a marijuana allergy may experience asthma-like symptoms, such as wheezing, which can affect their ability to breathe comfortably.
2. Ocular Symptoms: Itchy and swollen eyes are frequently reported by those with a marijuana allergy, leading to eye discomfort.

3. Skin Reactions: Skin-related symptoms may involve the development of hives, resulting in raised, itchy, and often red welts on the skin.
4. Nasal Symptoms: Allergic reactions to marijuana can lead to nasal symptoms, including sneezing, a runny or stuffy nose, and overall nasal discomfort.
5. Cardiovascular Effects: In some cases, marijuana allergy can cause a drop in blood pressure, which may result in lightheadedness or fainting.
6. Anaphylaxis: While rare, severe allergic reactions can culminate in anaphylaxis, a life-threatening condition characterized by a sudden drop in blood pressure, difficulty breathing, and other severe symptoms. Anaphylaxis requires immediate medical attention.
It’s important to note that most marijuana allergy symptoms in adults tend to manifest rapidly. However, there are instances where symptoms may have a delayed onset, emerging hours or even days after initial exposure to cannabis. Anaphylaxis, though exceptionally rare, can also occur following marijuana exposure. Recognizing the symptoms and understanding the severity of your allergic reaction is crucial. If you suspect a severe allergic response, such as anaphylaxis, it is imperative to seek immediate medical attention to ensure your safety and well-being.
