If you're someone who's interested in the benefits of hemp-derived THC products without the legal restrictions of marijuana, then CBD (cannabidiol) might have caught your attention. But what happens if you are allergic to CBD or cannabis in general? Are there ways to continue enjoying cannabis despite being allergic? In this blog post, we'll dive into the topic of CBD allergies and explore whether such allergies exist. We'll also talk about cannabis allergies beyond just CBD and discuss remedies that can help you use these products more easily with less uncomfortable side effects. So let's get started!

Understanding CBD Allergies

Allergies are a malfunction of the immune system where it overreacts to a substance that is normally harmless.
- Dr. Clifford Bassett

In a survey of 2,409 CBD users, 5% reported experiencing an allergic reaction to CBD.

CBD allergies can occur when the immune system mistakenly identifies cannabidiol (CBD) as an allergen, triggering an allergic reaction. While rare, some individuals may experience asthma-like symptoms such as breathing difficulty or itchy eyes. It's important to note that CBD allergies are different from side effects and not everyone will have an allergic response to CBD.

The Possibility of Terpene Allergies

Terpenes are aromatic compounds found in various plants, including hemp. These compounds give different strains their distinct smells and flavors but could potentially trigger an allergic reaction in sensitive individuals.

Symptoms like breathing difficulty, nasal congestion, runny nose, itchy eyes could indicate an allergy related to terpenes present in the cannabis plant. Be careful, as this can happen with some vapes potent with terpenes too.

Terpenes can cause allergic reactions in some individuals.


Did you know that besides terpenes, pollen from male cannabis plants and inadvertent cross-contamination during handling could potentially set off cbd allergies? Intriguingly, these allergic reactions might mimic those you'd usually encounter from hay fever or seasonal allergies, typically instigated by grass pollen. 

Enjoying Cannabis Despite Allergies

If you suspect that you have an allergy towards any component present within CBD or cannabis, it's crucial to consult with a healthcare professional for an accurate diagnosis. They can conduct tests and identify the specific allergen causing your symptoms. Of course you can always reference a know it all friend or family member too ;)

Depending on the severity of your allergies, there are different remedies that may allow you to continue enjoying cannabis:

  1. Avoiding Smoking: Inhalation methods like smoking can exacerbate allergy symptoms due to irritants present in smoke. Instead, consider alternative methods such as vaping or consuming edibles.
  2. Opting for CBD Isolate: CBD isolate is a pure form of CBD without any other plant compounds like terpenes or THC. This option eliminates potential allergens while still providing some of the benefits associated with CBD.
  3. Patch Testing: If you're unsure about your allergies but want to try using a new product containing CBD, consider patch testing first by applying a small amount on your skin and monitoring for any adverse reactions before using it more extensively.
  4. Allergy Medications: Over-the-counter antihistamines can help alleviate mild allergic reactions temporarily; however, they may not be suitable for everyone and should be used under medical supervision. And stick to regular doses of antihistamines, not hat man doses.

Remember that each person's experience with allergies is unique, so what works for one individual may not work for another. It's essential to listen to your body and seek guidance from healthcare professionals when needed.

Symptoms of CBD Allergies

Physical symptoms associated with a CBD allergy may include breathing difficulty, itchy eyes, and nasal congestion. Possible allergic reactions when consuming or using products containing CBD can range from skin rashes to very rarely life-threatening anaphylaxis. The severity and duration of allergic symptoms vary from person to person.

  • Breathing difficulty
  • Itchy eyes
  • Nasal congestion
  • Skin rashes
  • Anaphylaxis (life-threatening)

Terpenes and Allergies - Which are to blame?

Terpenes are natural compounds found in cannabis plants that can trigger allergies. Certain terpenes, such as limonene and myrcene, are commonly associated with allergic reactions. To identify products low in allergenic terpenes, look for CBD products made from pure cannabidiol (CBD) isolate or those labeled as "terpene-free." These options can help reduce the risk of breathing difficulties and other allergy symptoms.

If you suspect an allergy to CBD or cannabis in general but want to continue using these products discreetly, it's important to take necessary precautions. Keep a record of your symptoms and consult with a healthcare professional for guidance on managing your allergies without attracting unwanted attention from law enforcement, workplaces, or family members who may disapprove.

Managing CBD Allergies

Tips for managing CBD allergies include avoiding exposure to potential allergens by carefully reading product labels and choosing CBD products that are free from common allergens such as soy, gluten, and dairy. If experiencing an allergic reaction, it is important to seek immediate medical attention and inform healthcare professionals about CBD usage. Feel free to ask us here at The Green Nursery for our recommendations if you feel you may be allergic to certain cannabinoids or terpenes.  Also, any well informed dispensary should be able to do the same. If they don't, or act irritated, you probably should move to a more compassionate company.

Does CBD actually help some people with allergies? 

  • Some individuals have reported that CBD can provide relief from allergy symptoms such as nasal congestion and itchy eyes. However, it's crucial to note that the relief brought by CBD to allergy symptoms isn't fully understood. Medical professionals believe it may be linked to its potential anti-inflammatory properties. While CBD could help reduce inflammation and relieve some symptoms, it's not a definitive cure for allergies. Research is ongoing in this field to determine the full extent of CBD's effects on allergies.
  • As mentioned, CBD has anti-inflammatory properties, which may help reduce the immune responses associated with allergies. However, the presence of terpenes in some CBD products can trigger allergic reactions in some individuals, including symptoms such as nasal congestion, itchy eyes, and even breathing difficulty.  The anti-inflammatory properties are not likely strong enough to counter a full on allergy attack in this case.
  • It is important to note that while CBD may provide relief for some people, it is not a guaranteed solution and individual experiences may vary. Consulting with a medical professional before starting a CBD regimen is highly recommended, particularly for individuals with known allergies or sensitivities.

Common Symptoms of Cannabis Allergies. The tell-tale signs.

Common Symptoms of Cannabis Allergies. The tell-tale signs:

  • Skin rashes and hives can be a clear indication of a cannabis allergy. These allergic reactions can range from mild to severe, causing itchiness, redness, and swelling on the skin.
  • Nasal congestion and sneezing are common symptoms of cannabis allergies. If you find yourself constantly reaching for tissues or experiencing difficulty in breathing due to nasal blockage after consuming CBD or other cannabis products, it could be an allergic reaction.
  • tchy eyes and throat are another sign that you may have an allergy to cannabis. If your eyes become red, watery, or irritated after exposure to CBD or marijuana products, it's important to consider the possibility of an allergic response affecting your eyes and throat as well.

Differentiating panic from allergy symptoms.

When experiencing anxiety or a panic attack, the physical sensations can mimic those of an allergic reaction. Increased heart rate, shortness of breath, and chest tightness are common symptoms that can occur in both situations. However, it is important to note that anxiety and panic attacks do not typically cause hives, swelling, or itching like an allergic reaction does. So take note of those extra symptoms.

While both panic attacks and allergies can cause difficulty breathing and a rapid heartbeat, there are some key differences to look out for. Panic attacks often involve feelings of impending doom or fear of losing control, while allergies do not typically have these psychological components. Additionally, allergy symptoms usually include itchiness in the eyes or skin and swelling around the face or throat – which are not commonly associated with panic attacks.

'Fight or flight' response versus immune system response: It is essential to understand the difference between how your body reacts during a fight-or-flight response (such as during a panic attack) versus when it activates its immune system response (like during an allergic reaction). During a fight-or-flight response triggered by anxiety or stress hormones like adrenaline surge through your body causing various physical reactions such as increased heart rate and sweating - all aimed at preparing you for intense action; this is different from what happens during an immune system response where your body detects foreign substances (allergens) triggering mast cell activation leading to histamine release resulting in specific allergy symptoms.

Is there anyway to continue enjoying Cannabis if allergic?

If you're allergic to cannabis, there are still ways to enjoy its benefits. CBD isolate, which contains no THC or other allergenic compounds, can be a suitable alternative for those with allergies. Additionally, exploring different delivery methods like edibles or topicals may help reduce the risk of respiratory symptoms associated with cannabis allergies. The same is true both marijuana and smokable cbd hemp flower.

When dealing with an allergic reaction to cannabis and wanting to avoid trouble, it's important to prioritize your health. If you suspect an allergy but cannot seek medical assistance immediately, take antihistamines and try home remedies like rinsing your eyes or using nasal sprays for relief. Remember that discussing your symptoms openly with healthcare professionals is crucial for proper diagnosis and guidance on managing potential allergies.

Preload with these herbs or medicines to combat allergies.

Preload with these herbs or medicines to combat allergies:

  • Quercetin: a natural antihistamine found in foods like onions, apples, and berries
  • Stinging nettle: helps reduce inflammation and relieve symptoms like nasal congestion
  • Vitamin C: boosts the immune system and can minimize allergic reactions

In the Throws?

If you suspect an allergy but don't want to get in trouble, try these steps:

  1. Stop using the product immediately.
  2. Take an over-the-counter antihistamine to alleviate symptoms. Benadryl (diphenhydramine) is a good choice, as it is also a sedative, and may also help to calm any associated panic.
  3. If you are already a seasoned allergy sufferer and carry an epi-pen, use it if you feel you need to. 
  4. Lastly, if things seem dire, seek medical attention. It's better to get in a little bit of trouble than to die unnecessarily.

While cannabis may help with certain conditions, it's important to be aware of potential allergies. Common terpenes that people are allergic to include limonene and myrcene. If you experience breathing difficulties or itchy eyes when consuming cannabis products, consider alternative remedies discussed earlier or consult a healthcare professional for guidance.


In conclusion, it is important to consult a healthcare professional if you experience any allergic reactions while using CBD or cannabis products. They can provide guidance and help determine the cause of your symptoms. Additionally, conducting personal research and experimenting with different products may also be beneficial in finding what works best for you. Remember, everyone's body reacts differently, so it's important to listen to your own experiences and seek professional advice when needed.


Weed is the only thing that helps me, but I think I'm allergic. Help!

Weed can be a game-changer for many people, but what if you suspect you're allergic? Allergies to CBD and cannabis in general are possible, although relatively rare. If you experience symptoms like breathing difficulties or itchy eyes after using weed, it's worth exploring the possibility of an allergy. Consider trying alternative remedies such as CBD isolates or other hemp-derived THC products that may reduce inflammation without triggering immune responses. It's essential to prioritize your health and find solutions that work for you while ensuring discretion in situations where legal restrictions may apply.

What are the most common terpenes people are allergic to?

Terpenes, the aromatic compounds found in cannabis and many other plants, can sometimes be the culprits behind allergic reactions. Despite their potential benefits, including anti-inflammatory and analgesic properties, certain individuals may have sensitivity to specific terpenes. But which are the most common terpenes that people are allergic to? 

1. Alpha-Pinene: Alpha-Pinene is a terpene most commonly associated with the scent of pine trees. It's believed to have anti-inflammatory properties, but it can also cause allergic reactions such as skin irritation, runny nose, and itchy eyes. 

2. Limonene: Limonene is a citrusy terpene found in high concentrations in the peels of citrus fruits and in several cannabis strains. It's praised for its mood-lifting properties, but it can cause allergic reactions in some people, leading to respiratory issues or skin irritation. 

3. Linalool: Linalool, which carries a floral scent, is often used in aromatherapy for its calming effects. However, it's also known to cause allergic reactions in some people, such as difficulty breathing and skin rashes. 

4. Beta-Caryophyllene: Beta-Caryophyllene is a spicy-scented terpene found in black pepper, oregano, and some cannabis strains. While it's recognized for its anti-inflammatory properties, it can trigger allergic reactions like skin rashes and respiratory problems in sensitive individuals.
