Recent studies show positive results for CBD and asthma through a possible reduction in inflammatory processes associated with asthma. Asthma is a respiratory condition that makes breathing extremely difficult. Studies show that CBD can help with the respiratory aspect of asthma and its side effects. CBD is a proven bronchodilator and anti-allergic for supporting asthma. Check out the five best CBD oils for asthma & what dose to take.
CBD and Asthma: Does CBD Oil Help People with Asthma?
CBD may help with asthma, but the evidence we have is less than ideal, to say the least. But that doesn’t change the fact that asthma continues to affect millions of people in the U.S.
Conventional treatments are available, with different degrees of success. However, not everyone reacts well and might want an alternative option.
Although CBD and asthma are loosely connected, there’s a chance it may help with the difficult and potentially dangerous complications associated with the condition.
So does CBD oil work for asthma? If so, what are its benefits and limitations for using CBD for asthma? How do you even begin using CBD? We’ll discuss those questions and more.
Does CBD Oil Help with Asthma?
CBD oil may help with asthma, as it addresses some of the reactions – like inflammation – associated with many different conditions. However, research is pretty sparse on which (if any) types of asthma are controllable or treatable using CBD.
According to the American College of Asthma, Allergy & Immunology , there are six types of asthma:
- Exercise-induced bronchoconstriction
- Asthma-COPD overlap
- Adult-onset asthma
Again, we have little research to work with. From what we know so far, CBD seems to impact some kinds of asthma. Studies don’t cover all six asthma types. Allergic and non-allergic categories received the most attention, so we’ll focus on them.
Research on CBD and Allergic Asthma
As the name implies, allergic asthma symptoms start when triggered by allergens. This could range from pollen to cockroaches, according to the Cleveland Clinic .
CBD may support the treatment of allergic asthma – at least if you’re a mouse. A 2019 study in the European Journal of Pharmacology looked at allergic asthma in mice. They found that CBD helped reduce “airway hyperresponsiveness” through its indirect link with the CB1 and CB2 endocannabinoid receptors. Through these pathways, CBD helps alert the body to create an anti-inflammatory response.
There’s now evidence this experimental treatment works on humans. Naturally, we need more animal and human trials.
Research on CBD and Non-Allergic Asthma
Research into cannabinoids as bronchodilators in non-allergic asthma dates back several decades. A 1984 experiment published in Clinical Pharmacology & Therapeutics saw results with delta-9 and delta-8 THC but noticed no change with CBD.
However, the CBD dose was a massive 1200 mg – far above the necessary amount for a new consumer. Given cannabidiol’s biphasic behavior, such a serving might not have been necessary. “Biphasic” means CBD’s potency isn’t linear. Once you exceed your ideal dose, the benefits start to drop.
Below is an image showing a visual of what the Biphasic Effect is:
The researchers likely didn’t know or fully acknowledge this issue. It begs the question as to whether gradually introducing CBD might have yielded different results.
Could CBD have worked otherwise? Only full clinical human trials can answer that question.
What Does Asthma Do to Your Body?
Although asthma is well-defined, there’s no “textbook case.” In other words, every patient experiences different severities and triggers. Treatment responses may also differ.
But regardless of what you deal with, asthma’s inflammatory response constricts the airways, making it difficult to breathe. Inevitably, the reaction leads to things like coughing, wheezing, and shortness of breath.
Universally, it’s a condition that can be limiting or potentially deadly in the case of severe asthma. Oral and inhaled medications are available for treatment and prevention, but there’s no cure.
This may not be news to you as an asthma patient, but you might be surprised at how CBD oil may improve your quality of life.
We all know asthma is a potentially deadly respiratory condition, but how does it work? According to the American Lung Association , asthma puts the lining of your airways into a “hypersensitive state.” Airways become red and swollen, much like how our skin reacts to sunburns.
Some known asthma triggers include:
- Weather changes
While a trigger doesn’t necessarily lead to a life-threatening emergency, it likely will cause a “flare-up” or “asthma attack.”
While the airways inflame and constrict, surrounding muscles also tighten. In some cases, this can fully obstruct breathing. At this point, you’ll need urgent medical care.
Could CBD help with coughing, wheezing, and shortness of breath during an asthma attack? Theoretically, yes, it could. There’s a lot of supporting evidence for CBD’s potential anti-inflammatory properties. Since inflammation is the driving mechanism during a flare-up, there’s a chance CBD may work.
But – not to sound like a broken record – we need more research.
If treated, patients can live fairly normal lives. However, if you fail to address the problem, asthma could cause a condition called “airway remodeling.”
According to the American Lung Association, ignoring asthma eventually leads to long-term or permanent damage. Eventually, these scars worsen and reduce the effectiveness of asthma medications.
How is Asthma Treated?
Fortunately for patients, there are many treatment options. The American Lung Association tells us medications available for both long-term preventative solutions and short-term immediate relief.
One option is an anti-inflammatory medication. Again, this function brings us back to CBD and its reported potential to reduce swelling.
Preventing Asthma Attacks
Since there’s no cure for asthma, your only options are treatment and prevention. Remember that ignoring it is the worst thing you can do, so don’t wait.
Prevention is the best treatment. Prescription medicines can be very effective, but avoiding triggers is also an excellent way to avoid flare-ups.
What Asthma Patients Say About CBD for Asthma
Not only are there success stories, but many are quite old. This shows CBD and asthma were on a lot of people’s minds.
For instance, a Reddit post four years ago by “DoxyRuby” says:
“Within 2 days [of vaping CBD], I went down to using my rescue inhaler once or twice a day. For the last three weeks, I’ve used it a total of 4 times – once when I went out into the cold winter air, and three times when I went somewhere that was dusty and had dogs (which I’m allergic to).”
Similarly, an unnamed Reddit user was surprised by the effectiveness of CBD capsules, saying:
“I was experimenting with CBD capsules (also targeting other aches and pains) and it seemed to reduce the frequency and intensity of flare-ups. So was ok on a lower dose preventative.”
Are There any Side Effects of Taking CBD for Asthma?
Yes, CBD has some commonly-known side effects, but they’re mild and often temporary. A 2017 study in Cannabis and Cannabinoid Research noticed the following CBD side effects:
- Appetite changes
- Weight loss or weight gain
CBD also interacts with certain medications, which could trigger other side effects. It’s important to verify with a doctor first, as the interference could be dangerous.
We’ll get into that next.
Can CBD Interfere with Any Asthma Medications?
Yes, CBD could interfere with some asthma medications, but we don’t have a full list.
As for asthma, the District of Colombia Department of Health mentions just one medication so far. They advise that smoking cannabis reduces the levels of theophylline. The drug prevents asthma flare-ups by relaxing the airways.
We have no information about whether CBD oil or any ingested CBD interacts with theophylline. Along with asthma, the drug treats lung illnesses like chronic bronchitis and emphysema. The issue stems from CBD’s presence in the liver, which metabolizes CBD using the P450 liver enzyme family. Unfortunately, many medications do the same.
When forced to “share” the enzyme, CBD dilutes or increases the medication’s blood concentration. This problem could theoretically reduce or increase the effects of oral asthma medications.
Consequently, this can weaken the medicine’s benefits or trigger side effects. In a worst-case scenario, the contradiction could impact lung function.
How to Use CBD Oil for Asthma
It’s easy to use CBD oil for asthma. Dosing is a matter of slow titration, while you can easily measure your intake using a marked dropper.
Just hold the tincture under your tongue for 60-90 seconds (or as indicated on the label) and swallow.
But before you try cannabis oil for asthma, there’s some crucial information to keep in mind, including side effects, safety concerns, consumption methods, and dosing.
Do CBD Inhalers Help with Asthma?
Yes, it’s likely CBD inhalers help with asthma. Unsurprisingly, there don’t appear to be any human trials in something so specific. But the 2019 study mentioned earlier used inhalable CBD mist.
Again, the mist yielded promising results as a bronchodilator.
Is it Safe to Vape CBD with Asthma?
No, it’s not safe to vape CBD with asthma unless you fully understand your triggers. Some people immediately notice their airways relax from vaping CBD. However, if smoke exacerbates your asthma symptoms, inhaling CBD could cause a reaction.
It’s important to mention that cannabinoids vaporized in oil or e-liquid don’t generate smoke but rather a vapor aerosol. This could impact whether or not the CBD products trigger flare-ups.
Regardless, asthma patients shouldn’t vape or start using CBD until they speak with a doctor.
How much CBD to Take For Asthma
There’s no exact answer for a proper CBD dose for asthma. However, a 2017 study in Cannabis and Cannabinoid Research found that participants could consume up to 1,500 mg of CBD.
Unfortunately, we’re just as blind as they are in that area. We know that suddenly giving new users 1,500 mg of CBD isn’t the best approach. Again, CBD is biphasic, so it’s possible starting so high could hamstring cannabidiol’s effects.
Many factors influence dose, including:
- Symptom severity
Make sure to read our blog post on CBD dosing to understand how CBD dosing works and how you can maximize your results.
Type of CBD
The CBD products you choose also influence dosing. There are three categories to choose from:
- Full-spectrum : retains all cannabinoids and terpenes
- Isolate: no cannabinoids or terpenes other than pure (up to 99%) CBD
- Broad-spectrum : middle ground where only THC is filtered out
Isolate isn’t the best choice because it contains pure CBD without the other cannabinoids and terpenes to improve or focus the therapeutic effects. If you decide to use isolate, odds are you’ll need a lot more than its counterparts.
Full-spectrum and broad-spectrum are reportedly better than isolate. Full-spectrum CBD oil doesn’t deliberately filter out other compounds. Consequently, it could contain up to 0.3% THC.
Broad-spectrum manages to retain everything else while completely removing THC.
Using CBD for asthma is difficult since we know so little about its benefits or side effects. Vaping is fast-acting, but there are concerns about how it may trigger an asthma attack.
Oral CBD products are preferable, such as CBD oil or CBD gummies. They’re easier to dose than vaping, but you risk potential drug interactions.
How to Find Your Optimal CBD Dosage
You find your optimal CBD dosage through slow, steady increases. There’s some flexibility, but it’s best to use the lowest dose possible for the first few days, then gradually increasing as needed.
This “start low and go slow” method is meant to avoid taking too much CBD. Cannabidiol is biphasic, meaning it reaches a peak where additional CBD will reduce the effectiveness. Starting gradually not only prevents you from overshooting the “sweet spot,” but it also helps your body gradually adjust to CBD.

Final Thoughts on CBD and Asthma
CBD’s anti-inflammatory effects on asthma need way more research. Theoretically, there could be potential. Unfortunately, it’s unlikely CBD for asthma will be at the forefront of medical research.
Hopefully, in time, we’ll discover enough information to help improve the lives of asthma patients everywhere.
CBD and Asthma: Benefits of Cannabis Oil for Asthma Patients
According to the World Health Organization (WHO), around 339 million people suffer from asthma worldwide. Asthma is definitely one of the most prevalent chronic diseases that could use natural, safe, and effective treatment.
CBD is becoming more and more popular, so it’s no wonder some asthmatics have decided to choose it as an alternative to conventional remedies. However, many people are still concerned about using CBD for asthma, mostly when it comes to the right form of administration.
CBD is short for cannabidiol, one of the two major cannabinoids found within cannabis plants. It can be extracted from both hemp and marijuana, but the majority of CBD oils available for sale are derived from hemp due to its legal status.
Hemp-derived CBD products are legal in all 50 states. Economists from around the world refer to CBD as the modern gold rush — and for a good reason.
The “why” behind CBD’s popularity stems from its high versatility and excellent safety profile. Unlike THC, CBD won’t get you high.
But can you actually use CBD oil to relieve asthma and associated symptoms?
Let’s shed more light on it!
What You Need to Know About Asthma
Asthma is a common chronic respiratory illness that starts in the lung airways as a result of inflammation and swelling. As these airways become constricted, they get filled with mucus, making it difficult to breathe properly.
Asthma is categorized into several different types.
For example, a person may have allergic asthma, which involves an overactive immune system that causes respiratory problems upon being exposed to the allergen. Common allergens are responsible for causing asthma include dust mite, mold, cold, germ-ridden dirt, pollen, and pet dander.
According to various estimates, Asthmatics make for roughly 8% of the U.S. general population. The Centers for Disease Control and Prevention (CDC) reports that 10 Americans are diagnosed with asthma every day.
The symptoms of asthma include:
- Shortness of breath
- Pain and/or tightness in the chest
- Difficulty falling asleep
The symptoms may vary from person to person. They can also manifest at different events, such as during cold weather, when exercising, or being exposed to allergens.
Not all patients have severe asthma; for many people, this is a mild condition. However, others may have serious problems, such as severe asthma attacks, which can be life-threatening.
An asthma attack involves an immediate deterioration of symptoms. Often described as asthma flare-ups, they contribute to around 2 million emergency room visits per year and can have a negative impact on the person’s quality of life. Without proper treatment and immediate medical care, an asthma attack can result in death.
Can CBD Oil Help with Asthma?
As mentioned, some people find it very difficult to manage the symptoms of asthma. The treatment calls for taking a multi-angle approach to your lungs’ health. While you can use certain prescription medications to relieve the symptoms and stave off asthma flare-ups, many of these drugs have dangerous side effects.
Preventive inhalers can lead to a sore throat, tatty voice, and oral fungal infections when used regularly.
Other medications — leukotriene modifiers like zileuton — may sometimes increase the risk of depression, hallucinations, and suicidal thoughts.
There’s a growing body of evidence supporting the efficacy of CBD in respiratory conditions, including asthma. Preclinical findings suggest that CBD can relieve the symptoms of asthma and reduce the frequency and severity of the flare-ups.
Studies on CBD and Asthma
Although CBD isn’t a cure for asthma, it can effectively help in the management of its symptoms. The science behind these effects is pretty simple but requires some elaboration. Let’s have a look at the most vivid benefits of CBD for asthma.
CBD Oil vs Inflammation
Inflammation in the lungs is the main trigger of asthma flare-ups. When a patient gets exposed to irritants, such as allergens, the immune system brings an inflammatory response.
Inflamed airways may cause muscle spasms and cause the lungs to secrete too much mucus. As a result, the respiratory airways get clogged, making breathing in and out extremely difficult.
This is where CBD could help.
Researchers believe that CBD can produce remarkable anti-inflammatory effects through its interaction with the CB2 cannabinoid receptors within the endocannabinoid system. The activation of this receptor helps lower the concentration of pro-inflammatory cells such as C fibers.
In a 2019 study published in the European Journal of Pharmacology, the authors found that CBD may curb inflammatory responses and speed up the recovery of lung function in patients with allergy-driven asthma (1).
Similar findings were reported by an earlier study, where the research team concluded that CBD and other cannabinoids can be used to help people deal with respiratory conditions, inflammatory pain, and ischemic stroke (2)
CBD Oil vs Spasms
An asthma attack causes individuals to experience spasms that can impact the bronchi and bronchioles as a result of the muscle contraction in the lungs, which causes breathing difficulties and wheezing.
The latest research has shown that CBD has antispasmodic properties. As CBD reduces muscle spasms, it can help open the airways in the respiratory tract, relieving asthma symptoms. This property has also been highlighted in the studies designed to determine the therapeutic potential of CBD for epileptic seizures.
A 2015 study investigated the efficacy of Sativex — an oral spray containing a 1:1 ratio of CBD to THC — on patients with multiple sclerosis. The research team reported significant improvements in muscle spasticity and patients’ mobility (3).
Although more longitudinal trials are needed to prove the preclinically established benefits of CBD for asthma, the compound offers potential benefits for people who experience muscle spasms. There’s a chance that CBD may also help relax the muscles in the lungs, making it easier for asthma sufferers to breathe.
If you believe that CBD could help you manage the symptoms of asthma, consult a doctor prior to making a purchase for professional advice.
CBD Oil vs Asthma Drug-Induced Anxiety
Earlier in the article, we’ve mentioned that conventional anti-asthma medications can trigger anxiety in patients. Chronic anxiety can seriously impact a person’s daily life and is a risk factor for a wide range of mental disorders, including depression, panic disorder, phobias, bipolar disorder, and more.
CBD has demonstrated strong anxiolytic (anti-anxiety) properties in several experimental studies, so there’s a chance you can benefit from using CBD oil in conjunction with your prescribed medication to prevent anxiety (4).
However, since CBD interacts with about 80% of prescription medications, we suggest once again that you visit a doctor before buying CBD oil for asthma.
How to Use CBD for Asthma
CBD for asthma is available in a plethora of forms, including oils, capsules, edibles, vapes, and topicals. The choice of your go-to format depends on the preferred route of administration as well as on your lifestyle. Below we cover the most popular types of CBD products along with their pros and cons.
CBD oil is the most popular form of CBD. It is sold in dark, glass bottles with a dropper attached for accurate dosing. CBD oil contains a hemp extract infuse into a carrier oil such as MCT oil, hemp seed oil, or olive oil.
CBD oil comes in a wide range of concentrations and flavors. You can take it under the tongue and hold it there for 60 seconds before swallowing — or mix it with food and drinks to mask the strong taste of CBD oil (when taking full-spectrum or broad-spectrum CBD).
When you take CBD oil under the tongue, it absorbs through the many tiny blood vessels, avoiding the first-pass metabolism in the liver. As a result, the first effects are noticeable within 15–30 minutes after consumption.
CBD oil is good for people who can afford the time to take measurements and want their dose to be as accurate as possible. If you have a busy lifestyle, you may want to consider pills or edibles.
Capsules are the standard form of most health supplements, including CBD oil. This form of CBD is useful for consistent supplementation with fixed amounts of CBD per serving. However, CBD capsules are subject to the first-pass metabolism in the liver, which lowers its bioavailability. Only 1/5th of the ingested content will enter the bloodstream.
Since capsules need to be processed in the liver, it will usually take up to 90 minutes before you can experience their effects. But on the other hand, they will have a longer duration than oils — even 8–10 hours.
CBD edibles have become the next trend on the market. They offer a tasty, discrete, and portable way to consume CBD throughout the day. CBD edibles range from gummies to cookies, truffles, lollipops, protein bars, and chocolates.
Gummies are the most popular edible format. They look and taste just like regular gummy bears, with 5 mg to 50 mg of CBD per piece. Similar to capsules, edibles must pass through the liver before entering the bloodstream, so you may have to wait a bit for the effects to show up.
Capsules and edibles are good if you want to use CBD for prevention. However, if you need immediate relief from your symptoms, they are not the best option out there.
How to Inhale CBD Asthma Inhaler
For asthma sufferers, CBD vapes may act as asthma inhalers. If you want to inhale CBD, you’ll need a vape pen and some CBD e-liquid, also known as CBD juice.
A vape pen is a device that heats the CBD liquid to the point where it creates CBD-rich vapor. This vapor can be inhaled through the pen’s mouthpiece right into the lungs.
Many people confuse CBD oil with CBD vape oil or juice, but these are two different products. CBD vape oil is thinned with vegetable glycerin or propylene glycol (or a mix of both) so it can pass through the vaporizer’s chamber. Regular CBD oil is too thick to be vaped. If you tried using CBD oil in a CBD vape pen, you’d probably end up with a clogged device.
Vaping CBD is pretty straightforward. All you need to do is fill the cartridge of your vape pen with CBD liquid. Once done, turn on the pen and wait until it reaches the desired temperature. Most digital pens use a haptic signal (vibrations) to indicate that they’re ready for use.
The rest is simple: inhale and exhale, just as you would with an e-cig or CBD joint.
Is It Safe to Vape CBD with Asthma?
Although CBD is generally considered safe for asthma, vaping CBD oil raises some concerns about the safety of this particular method. When you vaporize CBD, you usually inhale cannabidiol along with the aforementioned thinners, which can further irritate your lungs and cause a flare-up. If you are sensitive to these additives (or flavorings), we recommend choosing a different form of CBD. The fastest way to experience relief from your symptoms will be through CBD oil.
How Much CBD to Take for Asthma
Now that we’ve established that the best type of CBD for asthma is CBD oil, let’s discuss the dosage.
This is the most difficult part of taking CBD for any condition.
There is no one-size-fits-all dosage because everybody reacts differently to CBD. Choosing the right dosage involves several factors, including:
- Unique body chemistry
- Previous experience with CBD
- The type of your asthma symptoms
- Medications for asthma you might be taking
An effective dosage may range from 5 to 300 mg of CBD. Experts in the field recommend starting low and gradually increasing your dose until you experience relief from your symptoms. It’s important that you consult your plans to incorporate CBD into your routine with your doctor. A doctor experienced in cannabis may help you establish the right dosage and avoid potential interactions with other medications.
Another thing to consider when trying to figure out how much CBD you should take for asthma is the cannabinoid spectrum of your product.
There are three types of cannabinoid spectra:
- Full-Spectrum CBD: full-spectrum products are extracted using the whole hemp plant. They contain CBD on top of other cannabinoids (including traces of THC), terpenes, flavonoids, essential fatty acids, vitamins, and minerals. These compounds work together synergistically to enhance the effects of CBD. This phenomenon is known as the entourage effect and explains why full-spectrum CBD oil is the desired option among consumers.
- Broad-Spectrum CBD: this type of CBD oil is much like its full-spectrum counterpart but without any THC inside. The THC has been removed during the later stages of extraction. Broad-spectrum CBD oil evokes some of the entourage effects and is recommended for people who are regularly tested for THC at work.
- CBD Isolate: true to its name, CBD isolate is just pure CBD that has been separated from other hemp compounds. The end product takes the form of white crystals or powder and has no odor or flavor. The advantage of isolate-based CBD products is their versatility and a high dose of CBD per servings. However, such products lack the entourage effect because there are no other cannabinoids and terpenes to support the effects of CBD.
Final Thoughts on CBD and Asthma
Asthma is a chronic respiratory disease that — when left neglected — can pose a real threat to one’s life. Common symptoms of asthma include shortness of breath, coughing, wheezing, and tightness in the chest.
Asthma doesn’t have a cure, meaning you’ll need to aim your treatment at the effective management of your symptoms and prevention of flare-ups. With inhalers, pills, and non-steroidal anti-inflammatory drugs (NSAIDs), it’s possible to live a normal life.
However, regular use of conventional medications has side effects, such as anxiety, depression, and suicidal thoughts on top of physical reactions including a sore throat and tatty voice from using asthma inhalers.
A growing number of people with asthma take CBD as a safe and effective alternative for dealing with symptoms without the aforementioned side effects. Some patients have experienced decent results of combining asthma medication with CBD oil.
A recent report from the WHO states that CBD is a safe and well-tolerated compound in humans.
Although no studies have been performed specifically on the use of CBD for asthma, there is evidence that CBD has a bronchodilatory effect, which can help relax the lungs and ease muscle spasms. Taking full-spectrum CBD oil may result in improved lung function and easier breathing.
If you’re planning to include CBD oil into your routine, we encourage you to make an appointment with your doctor in order to figure out the best dosage for your situation and avoid potential interactions with your anti-asthma medications.
Remember that smoking or vaping CBD isn’t recommended for asthma patients, as both methods entail a risk of deteriorating their symptoms.

CBD and Asthma: Benefits, How to Use, Dosage, & Side Effects
Asthma is an inflammatory immune condition — something CBD is particularly well-suited for. Learn how to use CBD products for asthma, and what to avoid.
CBD has risen to the forefront of treating numerous inflammatory conditions — leading researchers to begin exploring the benefits this versatile phytocannabinoid may offer asthma patients.
In 2015 it was estimated that 358 million people suffer from asthma around the world .
Only 183 million people reported to have diagnosed asthma three decades ago — these figures suggest that asthma is on the rise.
With this debilitating condition becoming more common as the years go on, medical researchers are frantically searching for new effective treatments for the condition.
Here we’ll go over the current research on CBD and its role in asthma. We discuss how to use CBD effectively, and what you can do to maximize the benefits.

Summary: Using CBD for Asthma
Asthma is an inflammatory disease of the airways — leading to difficulty breathing. Depending on the severity, asthma can interfere with the quality of life of those affected. It can even become fatal in severe cases.
Asthma caused by allergies is particularly dangerous because it leads to excessive mucus production in the lungs which further block air from entering the lungs.
CBD is thought to help in four main ways:
- Reduces inflammation in the throat
- Makes it harder for immune cells to attack the cells
- Relaxes tight muscles in the chest
- Alleviates common side effects of asthma (such as insomnia or anxiety)

Tips for Getting the Most Out of CBD and Cannabis Extract Use for Asthma:
- Always consult your doctor before using CBD with asthma
- If symptoms of asthma become severe, it’s important not to rely on CBD to alleviate symptoms. Always visit a doctor in the event of an emergency
- Start with a very low dose of CBD and build up the dose gradually to make sure you are not allergic to anything in the CBD product
- Always use CBD alongside other forms of treatment such as dietary and lifestyle changes
- If using CBD with children, always consult with a pediatrician before starting CBD supplementation and use CBD extracts made from isolate only
- Use oral CBD only — avoid smoking or vaporizing to get your dose of CBD
What is Asthma?
Asthma is a condition involving inflammation of the airway leading to the lungs — leading to difficulty breathing.
Symptoms of asthma can be anywhere from mild to life-threatening. Asthma can be present all the time or appear in the form of asthma “attacks” sporadically when being exposed to triggers like exercise or allergies.
Allergic asthma is considered an atopic condition — which involves other allergy-related conditions such as dermatitis and food allergies.
Atopic individuals tend to be hyper-reactive to a list of environmental compounds and foods. It’s most common in developed countries — affecting as many as 1 out of every 5 people .
There is no cure for asthma. Treatment is aimed at lowering the intensity and frequency of attacks, and identifying and removing triggers.
Asthma attacks are temporary periods of increased symptoms. In most cases, something triggered the attack — such as dust, cigarette smoke, exercise, or food allergies.
During an asthma attack, as the airway becomes inflamed, the amount of air that can fit through the bronchioles is reduced, requiring more effort to give the body the oxygen it needs.
Attacks can last anywhere from a few seconds to a few days.
Symptoms of Asthma
Signs of Emergency During an Asthma Attack
Although all asthma involves inflammation in the airway, there are a few distinct types of asthma depending on the cause:
What Are the Different Types of Asthma?
1. Allergic Asthma
Allergies are caused by an activation of the immune system to particular compounds. We can develop asthma symptoms from the same allergens that give us a runny nose, watery eyes, and itchy skin.
When we’re exposed to these compounds, the immune system identifies the compounds and sounds the alarm. Specialized cells known as mast cells release neurotransmitters like histamine that go on to cause most of the negative side-effects.
Our airway leading down to the lungs is high in these immune cells — their job is to make sure no infectious organisms find their way into the lungs where they can proliferate and make us sick. During an allergic asthma attack, it’s these immune cells that were there to keep us safe that make the condition worse.
Histamine released from mast cells causes the airway to fill up with fluid and close shut.
2. Non-Allergic (Intrinsic) Asthma
Other forms of asthma can happen without the activation of mast cells during an allergic reaction.
Our airway is controlled via the central nervous system. When we’re exercising, for example, the central nervous system makes the airway wider to allow more air into the lungs and then shrinks it up when we don’t need it to preserve heat loss and keep infectious organisms out of the lungs as much as possible.
In some cases of non-allergic asthma, the cause of the condition is mediated through the central nervous system dysfunction that leads to a narrowing of the airway. Medications or exercise can cause this form of asthma.
Causes of Non-Allergic (Intrinsic) Asthma Include:
- Aspirin-induced asthma
- Asthma with fixed airflow obstruction
- Exercise-induced asthma
- Cough-variant asthma
- Occupational asthma
- Nighttime (Nocturnal) asthma
- Asthma with obesity
Common Asthma Triggers
Measuring Asthma Severity
Doctors will often measure the severity of asthma symptoms using a 4-step scale.
Step 1: Intermittent Asthma
Asthma symptoms appear less than two days per week and don’t interrupt daily activities. This level usually involves short-lived flare-ups and rarely involves nighttime symptoms.
Step 2: Mild Persistent Asthma
The symptoms occur more than two days per week, but only slightly interfere with normal activities. This level of asthma may or may not involve occasional nighttime flare-ups.
Step 3: Moderate Persistent Asthma
The symptoms occur daily and interfere with daily activities. This level of asthma involves frequent nighttime and daytime flare-ups, and usually require medications to keep symptoms at bay.
Step 4: Severe Persistent Asthma
The symptoms occur throughout the day and may strongly interfere with daily activities. Asthmatics experiencing symptoms at this level often have difficulty with physical activity and frequently suffer from nighttime flare-ups.
Treatment Options for Asthma
- Adrenergic receptor agonists (Salbutamol)
- Anticholinergic medications (ipratropium bromide)
- Leukotriene receptor antagonists
- Mast cell stabilizers
Guide to Using CBD for Asthma
There are many different causes for asthma, but the underlying cause of symptoms remains much the same — inflammation and excess mucus production in the airway leading down to the lungs.
Therefore, the treatment is similar for different types of asthma — with one of the primary treatment options being anti-inflammatory compounds. CBD is a particularly strong anti-inflammatory — exerting beneficial effects over multiple different types of inflammation.
There are no clinical studies to date on the effects of CBD on asthmatic patients to confirm how effective CBD is on real-life patients, but there are a lot of studies highlighting the specific inflammatory messengers inhibited by CBD that play a role in regulating asthma attacks (more on this in the next section).
CBD is a promising supplement for reducing the underlying causes of asthma.
It’s important to speak with your doctor before using CBD and avoid smoking or vaporizing cannabis as your source of CBD. Opt for using other forms of CBD instead — such as capsules, oils, tinctures, and edibles. It’s important to let your doctor know if you want to try CBD since it interacts with some medications.
What Does the Research Say?
In 2015, an animal study was published involving rats who were treated with 5 mg/kg CBD for two days. After the treatment was finished, researchers measured the inflammatory activity in the animals. All inflammatory markers except for IL-10 were substantially reduced — indicating that CBD was able to lower the inflammatory factors driving the symptoms of asthma .
Asthma caused by allergic reaction involves an increase in specific immune reactive cells (Th2 cytokines) . Research shows that CBD specifically targets many of the Th2 cytokines including IL-6, IL-2, TNF-a, IFN-c, IL-6, IL-12, and IL-17 [6, 7].
|Inflammatory Messenger||Role In Asthma Reaction||Effects of CBD|
|TNF-a||Heavily involved with severe asthma reactions||Reduces Asthma Reaction|
|IL-6||Stimulates T-cell activity||Helps Prevent Asthma Triggers|
|IL-4||Stimulates IgE activity||Reduces the Severity of Asthma|
|IL-13||Increased mucus production||Prevents Excess Mucus Production|
This means that the anti-inflammatory effects of CBD work at several different levels of the inflammatory response. Multi-level treatment approaches such as this are far more effective than treatments focusing on only one aspect of inflammation.
Even conventional treatments use multiple treatment options such as steroidal inhalants (puffers) and oral medications.
How CBD Affects Asthma
- Inhibits inflammatory response associated with both allergic and non-allergic asthma
- Resists immune cell migration into the inflamed airway tissue
- Alleviates symptoms of correlated medical conditions like insomnia, anxiety, and mood disorders
- Relaxes the muscles in the airway and chest to reduce symptoms of asthma
Other cannabinoids such as THC provide powerful benefits towards asthma. Some of the effects of THC toward asthma include:
- Relaxes the airway to allow better flow of oxygen (bronchodilator)
- Reduces several different inflammatory markers linked with asthma
- Relaxes muscles in the chest and airway to reduce symptoms
What’s the Recommended Dose of CBD?
Figuring out the right dose of CBD to use with asthma symptoms requires a bit of trial and error. This is because everyone responds to CBD differently.
Most people take a medium or high strength dose of CBD to find relief for their symptoms.
However, it’s wise to start with a smaller dose first and build up gradually over time to make sure there are no allergies to the product you’re using — which could ultimately make asthma symptoms worse.
If you’re especially prone to allergies, it’s recommended that you take this one step further and start by placing some of the oil or tincture on the back of one hand. After about an hour, if you don’t show any signs of allergy, you can start with a very small amount of the CBD product in the mouth. If no side-effects or allergies occur after an hour, you can start with the low-strength dose.
Over the next few days try building the dose up gradually until you find relief from your symptoms.
