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.
CBD And Asthma
It has been known for many years that smoked Cannabis is a bronchodilator and can be useful in treating asthma. Usually, asthma is a problem with bronchospasm (wheezes) and increased mucous production in the smaller airways of our lungs. There is a large component of anxiety associated with asthma, as who would not be scared when it is difficult to breathe. More anxiety causes worsening bronchospasm, which causes more anxiety.
Typical inhalers contain adrenergic (adrenaline-like) stimulants, which work well but tend to heighten anxiety. It would be nice to have more alternatives to treat bronchospasm.
Since richer levels of THC can cause increased anxiety, using CBD seems like a reasonable thing to try. Last week a patient came into our office who had obtained some CBD-rich tincture at a local collective and said he felt it was helping his asthma. He was off of his Advair inhaler for a week and wanted to be “checked.”
We administered a baseline spirometry test and then repeated the test 15 minutes after the patient had taken three drops of his CBD-rich tincture. The graphic shows the result:
FEV1 is forced expiratory volume at one second (when the patient breathes out as hard as s/he can).
FVC is forced vital capacity (the amount of air you can blow out after taking a deep breath).
PEF is the peak expiratory flow rate at any point during the exhalation.
You can see that after a three-drop dose of the tincture taken sublingually, the patient’s FEV1 and PEF nearly doubled. This would generally be considered a great response to a typical bronchodilator!
It is well documented that CBD is a very potent bronchodilator and useful in the treatment of Asthma.
Taking CBD by any method does result in decreased airway resistance. So, how about taking it by inhalation without smoke?
Yes, how about that. So, now there are vape pens available that have CBD oil inside them. In general, a couple of puffs will give the patient 6-8 mg of whole plant CBD + some THC directly into their lungs.
We are looking into this for lung cancer as well.
Allan Frankel, MD Dr Allan Frankel is one of the few physicians in the US who truly understands Cannabis as a medicine. All treatments suggested have been well studied. Every patient seen by Dr Frankel is given a personally created Treatment Plan created with the patient’s specific issues defined. Plant medicine requires “tuning” of the dosing. Dr Frankel works with his patients thru a messaging portal. The use of this portal, allows quick and simple follow up contact with Dr Frankel. Patients are not charged for these messages, as this is how Dr Frankel has learned what he has learned. Follow up appointments in person or by phone/video are also available when needed
