COPD Oil Treatment for COPD

What is COPD?

Chronic obstructive pulmonary disease [2] is often shortened to COPD. The name doesn’t refer to a specific disease but rather a group of disorders that make it more difficult for the patient to breathe over time. Unfortunately, COPD is frequently misdiagnosed and many people who have it aren’t diagnosed until the disease has become advanced.

Here are some of the most common symptoms of COPD:

  • Cough
  • Sputum production
  • Wheezing
  • Chest tightness
  • Shortness of breath
  • Frequent chest colds

To diagnose you with COPD [3] , your doctor will perform a thorough review of your symptoms along with a physical exam. You’ll need to answer questions about your family and medical history as well as your exposure to lung irritants (including cigarette smoke). Your doctor may also need to perform tests such as pulmonary function tests, a chest x-ray or CT scan, an arterial blood gas analysis, and additional tests for an underlying health condition.

In order to be diagnosed with COPD, patients must have the following [4] :

  1. Emphysema – A condition in which the air spaces in the lungs become permanently enlarged as the disease destroys the walls of the air sacs.
  2. Chronic Bronchitis – This is a cough that creates mucus or phlegm and doesn’t go away for at least three months in two consecutive years – diseases and infections must be ruled out as a cause for bronchitis.
  3. Blocked Airflow – A symptom that usually worsens over time, reduced airflow in and out of the lungs is similar to asthma.

Though there is no cure for COPD, there are several treatment methods available that can help control the symptoms and improve your quality of life. If you are a smoker, the best thing you can do for yourself is to stop smoking.

Treatment Options for COPD

When it comes to COPD treatment, it is important to remember that the condition cannot be cured. Once you’ve done such significant damage to your lungs, you may not be able to regain their full health and function. That being said, COPD patients can slow the progression of their condition and keep symptoms under control with various forms of COPD treatment.

Here are some of the best treatment options for COPD [5] patients:

  • Stopping smoking to prevent further lung damage
  • Oral or inhaled medication to make breathing easier
  • Pulmonary rehabilitation to strengthen the lungs
  • Surgery to repair or replace the lungs (transplant)

In most cases, treatment for COPD patients is multifaceted. Lifestyle changes [6] may be required on top of medication, rehabilitation, and therapy. In severe cases, some COPD patients require surgery or lung transplant. Unfortunately, if your COPD is caused by smoking, you may not be eligible for a lung transplant until you’ve stopped smoking for at least 6 months. Smoking, drinking, and using drugs can increase the risk of health problems for a transplant patient.

Your doctor is the best person to talk to about COPD treatment, but it’s always a good idea to do your own research. If you’re concerned about the potential side effects of traditional treatments, you may want to look into alternative therapies – options like CBD can help.

What is CBD?

Cannabidiol or CBD [7] is one of several active compounds found in the cannabis plant. Different parts of the plant contain different concentrations of compounds called cannabinoids, of which CBD is one. Also known as the hemp plant, cannabis typically refers to the following species:

  • Cannabis sativa
  • Cannabis indica
  • Cannabis ruderalis

When it comes to understanding CBD, it is important to differentiate between CBD and THC [8] . Tetrahydrocannabinol or THC is a cannabinoid found in cannabis, much like CBD, but it affects the body very differently. This particular compound is psychoactive which means it can produce a high. Your individual response to THC (including medical marijuana) depends on how much you use and how often you use it. CBD, on the other hand, doesn’t have psychoactive properties and has become a popular alternative treatment for conditions like epilepsy, chronic pain, and anxiety.

When shopping for CBD products, it is important to do your research to know exactly what you’re purchasing. Many CBD products contain traces of THC [9] . In fact, it is legal in most states for CBD products to contain up to 0.3% THC by dry weight. You should also ensure the CBD products you choose are made with high-quality CBD and that the products have been tested by a third-party lab for purity and safety.

Does CBD Help COPD?

The goal of therapy for people with COPD is to stop the progression of the disease and to improve lung function. A combination of oxygen therapy and pulmonary rehabilitation can go a long way in improving the symptoms of various lung diseases like COPD, but other symptoms can be a little more stubborn.

One of the most common problems for people with COPD is shortness of breath [10] related to damaged lungs. Airway inflammation and inflammation in the lungs themselves can contribute to this problem – that’s where CBD could help. Though research regarding CBD products for the treatment of chronic obstructive pulmonary disease is limited, it could help mitigate some of your symptoms with its anti-inflammatory properties.

The benefits of CBD are thought to be linked to its effects on the endocannabinoid system. The endocannabinoid system or ECS is a complex cell signaling system [11] in the body that plays a role in regulating essential functions and maintaining biological homeostasis. Cannabinoids like cannabidiol and tetrahydrocannabinol bind to cannabinoid receptors (CB1 and CB2) and have the potential to trigger a variety of effects ranging from pain relief to reduced inflammation.

While few studies have been conducted using CBD specifically for COPD, a new oral anti-inflammatory drug called roflumilast [12] has shown great potential. If the anti-inflammatory effects of CBD are anywhere as strong as this medication, the benefits could be noticeable.

If you’re curious to try using CBD for your COPD symptoms, you’ll be glad to know there are many different forms to try. CBD oils are some of the most popular products, but you can also find edibles or topicals. Vaping has not been proven safe [13] , even with CBD, and any form of smoking is generally not recommended for people with lung disease.

CBD Oil and Your Lungs

The health benefits of CBD [14] have been well studied for conditions like epilepsy, anxiety, insomnia, and chronic pain. When it comes to COPD, however, there are few studies and many of them have only been done on animals. As scientific developments continue, however, testing in humans may lead to a better understanding of how CBD works on the central nervous system and other parts of the body.

In a 2015 study conducted in mice [15] , cannabidiol was administered to mice subjected to LPS-induced acute lung injury. Just 24 hours after CBD administration, the results showed decreased total lung resistance and elastance along with reduced production of pro-inflammatory cytokines. The researchers concluded that CBD has a potent anti-inflammatory effect and could be a potential therapeutic treatment to improve lung function.

Another study conducted on guinea pigs in 2014 [16] supports this hypothesis, showing reduced inflammation, cough, and improved lung function in the guinea pigs with damaged lungs treated with THC.

CBD Oil and Emphysema

Emphysema is a respiratory disease [17] that makes it difficult to breathe. This condition destroys the walls of the alveoli, the tiny air sacs in the lungs that enable the body to absorb oxygen through the blood. The most common symptoms of emphysema include shortness of breath, wheezing, weight loss, and loss of muscle.

Treating emphysema typically involves a combination of medications and respiratory system therapy. Bronchodilators may help open the airway while corticosteroids can curb inflammation and antibiotics may be used to treat lung infections caused by bacteria. Though there is no scientific evidence to support the use of CBD for emphysema, when used for the treatment of COPD cannabidiol may reduce inflammation and help COPD patients breathe easier.

How to Use CBD Oil for COPD

Since CBD was removed from the list of controlled substances in 2018, a wide variety of CBD products have hit the market. CBD liquids are the most common, but you can also find edibles as well as topical products. Talk to your doctor about the best option for you then do your research to find a reputable, trustworthy company. Though CBD products are generally recognized as safe [18] when used properly; quality and purity do vary. Be sure to purchase from a company that uses high-quality CBD and has its products tested by a third-party lab.

CBD Oil for COPD Dosage

There are no standards for CBD dosage because medical studies are still somewhat limited. Add to that the fact that CBD can help with a wide range of problems in different people, and you can see how it might be difficult to pinpoint a specific dosage recommendation.

Another challenge with CBD dosage for COPD is that different products have different concentrations of CBD. A CBD oil tincture could range from 100mg to 1,500 mg of CBD and the concentration per milliliter depends on how many milliliters of liquid is in the bottle. For example, a 30ml (1 ounce) of 100mg CBD oil tincture contains about 3mg of CBD per ml. A 1000 mg concentration, however, contains over 30mg of cannabidiol per ml.

In many cases, it comes down to trial and error. Even if CBD doesn’t resolve all of your COPD symptoms, the chances are good that your body will experience some kind of health benefits.

Safety and Side Effects

Before taking CBD, it’s important to consult your doctor. Even though CBD is a natural substance, there is always the potential for drug interactions. If your body is already weak from lung damage, you may be more susceptible to interactions and the side effects of CBD.

The most commonly noted side effects of CBD [19] are:

  • Drowsiness
  • Diarrhea
  • Changes in appetite
  • Weight changes
  • Temporary drop in blood pressure

In addition to being aware of the potential for negative interactions, it’s important to choose CBD oils wisely. Shop for CBD brands based in the United States to ensure their offerings adhere to the safety regulations enforced by the FDA. Do your research to find out where the company gets its hemp and be sure it is tested by an independent lab for safety and purity.

Frequently Asked Questions

Because there is no cure for COPD, CBD oil will not cure it. It is possible that CBD could help reduce inflammation or relieve pain associated with COPD.

Pure CBD alone will not show up on a drug test, but if you’re worried you should double-check to make sure you’re using a THC-free product. Even CBD oils containing less than 0.3% THC may trigger a positive result.

There is no scientific evidence supporting the use of CBD for COPD (chronic obstructive pulmonary disease) and no standard dosage. Talk to your doctor and refer to the dosing instructions on your CBD product for recommendations.

Several mouse studies have shown that CBD can improve respiratory function, likely due to its anti-inflammatory properties.

    Chronic obstructive pulmonary disease is a serious and chronic illness. Here’s what you need to know about the best CBD oil for COPD 2020.

    Chronic Obstructive Pulmonary Disease (COPD): Cannabinoids and CBD Research Overview

    The third leading cause of death in the United States, COPD is a group of lung diseases that block airflow and make it difficult to breath. Research indicates that cannabis can help patients manage the pulmonary diseases by reducing airway inflammation and causing bronchodilation.

    Overview of COPD

    Chronic obstructive pulmonary disease (COPD) is a progressive inflammatory lung disease that obstructs airflow to the lungs and makes it difficult to breathe. In the United States, COPD is most commonly associated with the development of emphysema and chronic bronchitis.

    When a person has COPD, less air flows in and out of the airways because either they lose their elastic quality or make more mucus than usual, causing clogging. In chronic bronchitis, the walls of the bronchial tubes become thick and inflamed. In emphysema, the walls between the air sacs can be destroyed, reducing airflow.

    COPD is caused by long-term exposure to irritating particulate matter or gases. The number one cause of COPD is cigarette smoking, but other irritants like secondhand smoke, air pollution and workplace exposure to dust and smoke can also pose problems. The disease develops slowly and symptoms get worse over time until even the most basic physical activities, like walking or cooking, became too difficult.

    The symptoms associated with COPD typically include the coughing up of large amounts of mucus, shortness of breath, wheezing, and chest tightness. Symptoms often don’t appear until significant damage to the lungs has already occurred. A major cause of disability, COPD is most commonly diagnosed in middle-aged or older adults.

    COPD has been shown to increase the risk of respiratory infections, heart problems, lung cancer, high blood pressure and depression.

    There is no cure for COPD and as of now, damage to the airways and lungs are irreversible. However, treatments can help control symptoms and reduce the risk of complications and exacerbations. Bronchodilators are medications that can be used to relax the muscles around the airways. Inhaled steroids help reduce airway inflammation.

    Findings: Effects of Cannabinoids and CBD on COPD

    Studies indicate that cannabis could potentially be therapeutically beneficial for managing acute attacks of airway constriction due to inflammation, thereby acting as a preventative measure for patients with COPD. Cannabis has been shown through numerous studies to have efficacy for reducing inflammation, suggesting it could be effective for helping manage inflamed airways in those with chronic bronchitis 4,8,11,17 .

    Two of the major cannabinoids found in cannabis, tetrahydrocannabinol (THC) and cannabidiol (CBD) have shown in several studies to have anti-inflammatory benefits through a variety of mechanisms 14 . THC and CBD interact with the endocannabinoid system’s cannabinoid receptors (CB1 and CB2) to help the body maintain homeostasis . The activation of CB1 and CB2 receptors has shown to reduce airway inflammation 3,6 . An animal study concluded that CBD has a potent anti-inflammatory effect and also improves lung function, suggesting it could be a useful therapeutic tool for the treatment of inflammatory lung diseases 10 . In another study, CBD was shown to have anti-inflammatory effects following acute lung injury 9 . Studies have also found that terpenes, the aromatic compounds found in cannabis, show anti-inflammatory benefits 7 .

    Some research has also shown that the cannabinoids found in cannabis can have bronchodilatory effects, thereby decreasing resistance in the respiratory airway and increasing airflow to the lungs 12 . One study found that cannabinoids’ activation of the CB1 receptor inhibits contraction of the smooth muscle surrounding the lungs to dilate the bronchial tubes and further open up the airways 7 .

    It’s important to note that findings in several studies suggest that the smoking of Cannabis may increase the prevalence of acute and chronic bronchitis due to irritants entering the lungs 13 . Heavy smoking of Cannabis on its own can cause airway obstruction 1,16 . These findings suggest that patients with COPD should stick with cannabis products that are delivered through methods other than smoking, such as cannabis oils and edibles.

    States That Have Approved Medical Cannabis for COPD

    While no states have approved medical cannabis specifically for the treatment of COPD, several states will consider approving medical Cannabis for the treatment of other conditions, but require an approval or a recommendation by a physician. These states include: California (any debilitating illness where the medical use of cannabis has been recommended by a physician), Connecticut (other medical conditions may be approved by the Department of Consumer Protection), Massachusetts (other conditions as determined in writing by a qualifying patient’s physician), Nevada (other conditions subject to approval), Oregon (other conditions subject to approval), Rhode Island (other conditions subject to approval), and Washington (any “terminal or debilitating condition”).
