Cannabis allergy: symptoms, remedies and prevention of this disorder

Cannabis allergy: symptoms, remedies and preventio

Modified on: 19/04/2024


If you live, chances are you have never had an opportunity to consider a possible cannabis allergy.

The same cannot be said for all those workers employed in marijuana cultivation facilities that are now considered legal (such us selling CBD weed is legal) in many states of the world.

For some unfortunate people, prolonged exposure to pollen or contact with this plant has created quite a few problems. Specifically, a true cannabis allergy has been diagnosed in more than one case.

But what does it depend on? And what are the symptoms with which it manifests itself?

In this article, I talk about marijuana allergy, the most common symptoms and the treatments available to limit the consequences.

What can be the causes?

As with many allergies, one of the leading causes is pollen from marijuana flowers. Excessive exposure can cause classic pollen allergy symptoms such as rhinitis, reddening of the eyes and breathing difficulties.

Often, however, the allergic reaction to cannabis may result from cross-reactions with other factors not directly related to the plant.

What can be the causes?

In particular, it may happen – and has already happened – that the buds, not appropriately stored during drying, are exposed to mould and other pathogens. In this case, mould-allergy sufferers have noticeable allergic reactions mistakenly associated with cannabis consumption.

In addition, exposure to or inhalation of marijuana smoke may also lead to the appearance of allergic reaction symptoms.

But as you know, cannabis – in countries where it is permitted by law – is not only consumed in the form of a joint. It is possible to ingest it and, less rarely, experience symptoms associated with food intolerances.

How to realise that you have a cannabis allergy?

As mentioned above, the symptoms of a marijuana allergy are not dissimilar to classic generic allergic reaction symptoms.

Specifically, we are talking about rhinitis, bronchial asthma, conjunctivitis and, in less frequent cases, hives may even be triggered.

An excellent way to hypothesise a hemp allergy is to pay attention to the reactions’ timing. In other words, if you notice the appearance of skin or respiratory reactions every time you deal with cannabis, regardless of the mode, you most likely have this allergy.
As a rule, symptoms occur more or less thirty minutes after taking the substance.

Among the most common symptoms are:

  • itching of the eyes and throat
  • rhinitis;
  • itching of the skin, with possible swelling or redness;
  • frequent sneezing and nasal congestion;
  • reddened and watery eyes;
  • nausea or vomiting;
  • dry cough.

These are the main symptoms found in allergies to pollen or cannabis smoke. But it is possible, as mentioned above, to develop hypersensitivity to the plant even if it is ingested.

Specifically, the appearance of painful and frequent abdominal cramps is an alarm bell in this respect.

In most cases, the reactions are transient and minor.

However, the same cannot be said for other, far more worrying symptoms that indicate a severe and dangerous allergy. So if, after having contact with cannabis, you find yourself experiencing any of the following symptoms, please do not underestimate the situation.

In sporadic cases, the reactions experienced are more severe. These include:

  • dyspnoea;
  • palpitations;
  • urticaria;
  • dizziness;
  • reduced blood pressure;
  • loss of consciousness and fainting.

These symptoms, like the previous ones, are not to be taken lightly. Neglecting an allergic reaction symptom situation can even lead to the onset of anaphylactic shock.

Is there anything that can be done to limit the damage? In the case, for example, of people who are unable to avoid contact with cannabis for work reasons, is there any remedy to keep the allergy under control?

But what can be done to treat the allergy?

But what can be done to treat the allergy? Is there a therapy? The study

Regarding research and therapeutic strategy, Dr Williams Silvers, an allergist from Colorado, has made an essential contribution to scientific research.

Due to the complete legalisation of cannabis in Colorado, more and more cases of apparent cannabis allergies have slowly started to occur.

In his 2016 editorial, Dr Silvers examined three particular cases of patients with symptoms attributable to marijuana allergy.

Through his study, the allergist gives us a comprehensive and in-depth view of his practical experience following legalisation.

Patient number one, a regular cannabis user, began presenting with mild nasal congestion that soon became a chronic cough. His condition worsened with the start of a new job: being employed as a trimmer at a cultivation plant. Therapy with an inhaler and nasal spray significantly reduced his symptoms.

Similarly, patient number two started experiencing allergy symptoms after obtaining a job at a cultivation facility with an attached dispensary. In this case, it is essential to emphasise that the patient had never shown any signs of asthma or allergies.

The initial discomfort soon evolved into asthma and hay fever diagnoses, resulting in eye inflammation and suspected marijuana contact dermatitis.

In this case, the recommended therapy involved minimising exposure to cannabis, and the patient improved considerably with the support of antihistamine medication.

However, the third and final case consists of a different and much more severe experience. The patient presented with symptoms of suspected anaphylaxis, and as a result, he ended up in the emergency room. He stated that he had consumed a cannabis wax containing very high levels of THC (over 60%). The curious aspect, however, concerns the allergy tests performed on cannabis derivatives and its pollen: all negative.

The hypothesis is that the allergic reaction was caused by the solvent used to extract the THC concentrate. However, there are not enough scientific studies to assess the safety or non-contamination of certain products, such as BHO.

Dr Silvers’ final considerations suggest that, given the low frequency of cases since the legalisation of marijuana, cannabis is a minor allergen, and significant exposure is required to elicit respiratory or dermatological allergic reactions.

Such considerations may be reassuring for cannabis enthusiasts, especially concerning the availability of effective therapy to reduce symptoms. But unfortunately, for heavily allergic smokers, the only solution is abstention from contact with the plant.

The situation is slightly more complicated for those who cannot choose not to come into contact with marijuana, especially for work-related reasons. In these cases, various pharmacological therapies are available, but they will only serve to alleviate the extent of the symptoms.

In conclusion, what do we know about cannabis allergy?

Information on this allergy is not particularly plentiful, probably due to the ban imposed by law, which severely restricts access to the substance.

The little available research comes mainly from the United States, where, following the legalisation of marijuana in several states, it has been possible to examine the consequences of prolonged contact with pollen.

According to the study reviewed in this article, cannabis allergy exists and can be treated like any other allergy, reducing symptoms mainly with the help of corticosteroids and antihistamines.

A further factor to consider is whether the CBD buds have been stored incorrectly during the curing process and therefore show traces of mould and other pathogens.

In this case, you only need to rely on the experience of professionals, first and foremost, who will guarantee perfectly dried and stored CBD cannabis buds, CBD hash and CBD oil.
