cbd and asthma

December 15, 2021 By admin Off

Contrary to popular belief, cannabis can be a valuable aid for people with respiratory disorders. Although the use of CBD is becoming more and more popular in the context of diseases such as anxiety, depression, diabetes, or epilepsy, it is still little known in the world of respiratory pathologies. So, how does CBD act on asthma? What are its benefits? What is its mode of action? And above all, how can people with asthma consume CBD in a totally healthy way, without any risk to their health? This is what you will discover through this article dedicated to asthma and CBD.

As previously explained, American studies revealed several decades ago, the usefulness of cannabis to dilate the airways . At the time, scientists focused on the THC molecule to support their claims. But now, studies show that CBD has the same ability. It is important to note that the bronchodilator effect of hemp is weaker than that of conventional drugs, but that they are long lasting.

According to the results of a Brazilian study conducted in 2019, CBD causes immunomodulatory effects that activate CB1 and CB2 receptors located in the central nervous system and in immune cells. This study conducted on mice does not yet allow us to say that CBD could remodel the airways and permanently cure people with this pathology. On the other hand, it reveals the impact of CBD on the reduction of inflammation, and therefore, the frequency of asthma attacks .

The effects of CBD on asthma.

In the 1970s, American researchers had already emphasized the bronchodilator effect of cannabis , and more particularly of the cannabinoid tetrahydrocannabinol (THC). Although it is illegal, THC could dilate the airways, according to these first scientific studies. Today, it is the virtues of cannabidiol (CBD) that interest us.

If consumed in a healthy way, therapeutic cannabis is said to have expectorant and decongestant effects . These effects are still controversial, as scientific studies on this subject are quite rare. However, some Asian countries such as India and China have been using hemp for several millennia for its anti-mucosal effect .

During an asthma attack, the patient can inhale so-called beta-2 sympathomimetics with a spray. These active substances allow the airways to expand rapidly in the event of a very intense attack. In the long term, people with asthma also take anti-inflammatory drugs such as corticosteroids to limit the production of mucus and the swelling of the airways.

The easiest way is to use CBD oil. You can use it sublingually , by pouring a few drops directly under your tongue . You can also ingest it orally , by putting a few drops in your food and drinks .

CBD also has the ability to soothe muscle spasms . This is particularly useful during asthma attacks, as the airways contract and narrow in an involuntary and uncontrollable way.

Crumbled, the flowers and resins can also be consumed through your culinary preparations . Generally, they are used in herbal teas . To make a CBD-based infusion , simply add a fatty substance to the boiling water to facilitate the dissolution of the cannabinoids. Alternatively, you can use a CBD vaporizer . Indeed, most asthmatics are used to inhalers, so using a vaporizer can be very effective in combating asthma attacks, without any adverse effect on the throat or lungs .

Anti-mucosal effect.

Asthma is a chronic disease that manifests itself by an inflammation of the lungs and a narrowing of the airways . In addition, asthma stimulates the production of mucus, which can also cause coughing fits and shortness of breath . All these symptoms usually only occur during asthma attacks. Outside of these attacks, people with asthma have almost no symptoms. They are simply more fragile and sometimes experience great difficulty in carrying out simple physical activities such as running, which requires good breathing.

As early as 1970, scientific studies emphasized the enormous potential of therapeutic cannabis to treat certain respiratory diseases such as asthma. Indeed, it seems that the cannabinoids naturally present in hemp plants are particularly beneficial in relieving asthma symptoms.

Asthma is a respiratory disease characterized by chronic inflammation of the lungs and hypersensitivity in the airways. At present, there is no medical treatment or cure for asthma. Very disabling in daily life, this condition can cause sudden and intense allergic reactions due to a failure of the immune system. Faced with the lack of effectiveness of medical treatments, more and more asthmatics are turning to new natural alternatives such as cannabidiol (CBD).

The problem with these medications is that they often cause severe side effects such as heart problems, agitation, tremors, stomach problems, and sleep disturbances. To counteract these harmful side effects, some people with asthma resort to the alternative of CBD.

The advantages of CBD compared to a classic treatment.

Obviously, it is not recommended to smoke CBD, let alone for people with asthma. It could develop bronchitis, and simply worsen some symptoms. But rest assured, there are many healthy ways to consume CBD.

CBD is not a medicine, and it cannot cure any disease. Nevertheless, the use of CBD oil, flowers or resins can bring many benefits to asthmatics looking for a natural alternative to their medication. As a reminder, even drug treatments cannot cure asthma permanently, but they can help reduce the frequency and intensity of attacks.

Unfortunately, there is no cure for asthma to date. That’s why drug treatments aim to reduce the frequency and intensity of asthma attacks, but cannot stop them. In addition to medication, therapy consists mainly of maintaining the patient’s lung function by means of breathing exercises.

CBD also reduces the production of inflammatory cytokines in the immune system. Generally speaking, it regulates the receptors of the endocannabinoid system responsible for the perception of pain . Well known for its anti-inflammatory properties , CBD soothes the lungs and limits the occurrence and severity of asthma attacks.

Before taking CBD alongside any other medication, it is always best to seek the advice of your doctor. In any case, CBD is a natural substance that generally does not cause any problems when mixed with other substances. On the contrary, CBD can relieve many symptoms, limit the onset of attacks, and offer a better quality of life to asthmatics.

Broad-spectrum CBD oil has a very similar composition to full-spectrum CBD oil and contains many naturally occurring compounds in the cannabis plant but has little to no THC.

CBD oil also acts as a bronchodilator [12] which may benefit those with asthma symptoms by dilating the respiratory airways.

Keep in mind, any product that contains traces of THC may result in a failed drug test. If you are concerned or plan to be drug tested, it may be a good idea to avoid CBD products altogether.

Types of CBD Oil.

While research supports the idea of CBD oil for the treatment of asthma, it is essential to discuss adding CBD oil to your current medication regimen before purchasing.

In addition to its anti-inflammatory properties, CBD may also decrease hyperresponsiveness [4] in your respiratory airway by reducing sensitivity to triggers that may cause an asthma attack.

Until additional studies are complete, it may be a good idea to avoid vaping CBD oil.

CBD use is becoming increasingly popular for its effect on the immune system and its anti-inflammatory properties.

For asthma patients, managing symptoms associated with asthma attacks can be very difficult. Providers may order several prescription medications for treatment during or before attacks. These drugs are also known as rescue drugs. Still, most if not all of them have unwanted side effects [2] .

At this time, the Food and Drug Administration has not approved a medication containing an active ingredient derived from marijuana to treat asthma attacks.

Although CBD is relatively safe and tolerated by most people, some have reported minor symptoms. According to one review [9] , the most common side effects associated with CBD use are:


CBD, also known as cannabidiol, is one of the two main active ingredients in cannabis or marijuana. It is derived straight from the hemp plant and does not cause the “high effect” associated with marijuana use. It has become increasingly popular to treat a variety of health conditions. As of now, the FDA has only approved one drug comprised of CBD to treat epilepsy.

According to a study [3] from 2019 by the European Journal of Pharmacology, CBD consumption decreased inflammation and improved lung function in mice with experimental allergic asthma.

Though there is no research-backed recommended amount, most products will have dosage guidelines on the label.

According to a review [14] by the World Health Organization in 2017, CBD oil is generally safe for most people.

Few clinical studies show proper cannabidiol treatment for asthma, so the adequate dosage for treating asthma-associated symptoms is unknown.


Some patients with severe asthma and difficulty breathing may require a combination of medication and natural remedies to treat symptoms, making it essential to seek medical expertise before adding or changing your medication regimen.

While there is a possibility that you can add CBD oil to your medication regimen to treat symptoms associated with asthma, it is always essential to ask your doctor before starting or stopping medications. Many people think they do not have to discuss natural supplements with a medical provider. Contrary to popular belief, natural compounds can cause side effects and potential adverse reactions when combined with certain drugs.

Like CBD oil for asthma treatment, there should be more research to verify the effectiveness of CBD for COPD symptoms.

While individuals use both medical marijuana and CBD to treat asthma symptoms, CBD may be classified as a better option. CBD is less likely to cause addiction and does not result in hallucinations. There is also a question of whether medical marijuana may harm the lungs.
