A Guide to Cannabis Allergies and Symptoms

Allergies are irritating. However, it is hard to find someone who doesn’t carry at least one allergy. Cannabis allergies can occur in more than one way.

Allergies are irritating. However, it is hard to find someone who doesn’t carry at least one allergy. As per one of the findings on allergies, more than 50 million US citizens fall to some allergy every year.

Whether it’s food, scent, mold, or pollen, allergies remain a significant player in the globe’s health sectors.

Allergic to Something You Love

One of the saddest things for anyone is to fall allergic to something that they love. It’s even more critical if you need something that you’re allergic to.

Cannabis is one of the things that come under this category. In the recent past, there have been several cases of Cannabis allergies in the US. Moreover, the rate of allergies continues to grow after the legalization, following growth in sales and production.

Generally, the budtenders, medical patients, and recreational users have all faced some allergenic symptoms that open doors to a new debate regarding weed allergies.

Leafly shares its insights on the story as we discuss the key takeaways about cannabis allergies and symptoms.

General User Complaints

Generally, a cannabis allergy complaint features a pattern. The users mention symptoms like runny nose, watery eyes, bad allergies, stuffy head, etc. People complain of burning eyes and minor arthritic pains.

More importantly, the affected ones find it hard to learn about these symptoms because of lack of content. However, this post will help you through the process of understanding weed allergies.

The Allergies are Rising

Marijuana research went silently about its job for decades. However, it’s time for marijuana research to peak following legalization orders and promote research-based growth of these plants.

While cannabis research gains strength, the allergies are slowly catching up too. Interestingly, it’s no rocket science to correlate the allergies and legalization measures in the US.

The Spread of Pollen

To understand the reasons for rising allergies, we must focus on the essence of marijuana plants. Cannabis pollen can spread miles, so it’s easily distributed on fields. Therefore, they become more potent irritants.

Although cannabis pollen is produced by male plants only, hermaphrodites add to the problem. These are Cannabis plants that carry both male and female organs and can produce pollen.

Cannabis Consumption Methods

Cannabis consumption methods also become a significant contributor to the rising allergies. You can either smoke, chew, and use CBD tinctures to consume for recreational or medical use. 

Moreover, when the female Cannabis is isolated, it increases the THC content, which is one of the primary reasons for increasing allergies. 

It’s a critical reason why the potency of Cannabis plants has risen dramatically over the last few years. Since THC is a potential allergen, it can be considered one of the contributors.

Cannabis Allergies

Since allergies are an immune overreaction in the body, it protects the respiratory system from external invaders. Hence, one of the normal allergic reactions is sneezing. Therefore, pollen is one of the most common reasons for allergies.

However, pollen and molds are two different things, and they can cause different reactions in a body, even both are related to Cannabis.

Difference Between Allergic Reactions and Allergenics

So, how do we differentiate between allergic reactions and an allergenic substance? It may seem similar, but here is an example: If Cannabis catches mold over time, a person may get an allergic reaction from the mold. It doesn’t mean that the plant itself had any allergenic.

On the other hand, if a person’s body reacts to the plant itself, it may be due to the allergenic. Anyhow, some people can experience both reactions at the same time.

It may sound confusing, but fungal contamination is a thing with marijuana. It often puts patients at risk of invasive disease. For instance, a case of Bronchopulmonary Aspergillosis was observed and found related to marijuana contamination. The treatment required the use of steroids.

Simply put, a true Cannabis allergy is a reaction to any specific substance inside the Cannabis plant. IN this regard, Cannabis Sativa is well-known for being a weed allergen.

Different Modes of Catching Cannabis Allergies

Cannabis allergies can occur in more than one way. It generally depends on the exposure of a person to the plant. Generally, people living in areas with larger marijuana fields tend to experience more of these symptoms as the pollen density is much greater.

According to a study in Nebraska, Cannabis sensitization caused allergic rhinoconjunctivitis in 61% of the patients. There were signs of asthma, and they reacted positively to skin irritation tests too. For those who don’t know Rhino conjunctivitis symptoms, here is a quick list:

  • Post-nasal drip
  • Sneezing
  • Nasal Congestion
  • Runny nose
  • Itchy eyes or nose
  • Red eyes

The study showed that 73% of the patients showed respiratory symptoms. Another study found that marijuana can cause skin irritation as nearly 15% of the patients reacted positively to the skin test.

Identifying Marijuana Allergens

It’s slightly tricky to figure out marijuana allergens. At times, people who are allergic to weed pollen may be allergic to pollen from other plants. Therefore, there have been considerable efforts to identify Cannabis allergens.

According to a study published in 1971, some Cannabinoids react positively to the skin prick test. In this regard, THC is well-known for causing allergies, as suggested by a forensic laboratory worker who handled sinsemilla Cannabis variants.

Allergy Test

If you want to know how you react to allergens in Cannabis, you will need to go through a test. Generally, physicians take a skin test where they drop Cannabis extract to different parts of your skin. It’s called the Skin Prick Test.

As the body reacts to an allergen, it produces Immunoglobulin that helps specify the allergen through a blood test. The prick test is non-invasive.

However, if your test turns out positive for any allergen, it doesn’t mean that your body will react to it every time. Hence, physicians also consider the time and venue for testing.


Cannabis allergies are growing every day because of the general acceptance and legalization measures in the country. However, it serves to understand the weed allergens better that can potentially lead to more breakthroughs in weed research.
