CBD and Lung Fibrosis, Bronchitis, COPD, and Pneumonia

CBD Oil for Lung Fibrosis, CBD for Bronchitis, COPD, and Pneumonia

If you have been diagnosed with any lung-related diseases before, you might have encountered the term CBD or cannabidiol. 

CBD is a naturally-occurring compound (aka cannabinoid) found in the cannabis plant. This compound’s quickly-selling therapeutic marketability is being commercialized into different forms – creams, lotions, oils, tinctures, gummies, shampoos, lip balms, and more. 

In 2018, the CBD usage rate in the United States was about 6%. It’s estimated to increase at 35% by 2024.  

Recently, CBD trended again, this time, in the context of COVID. In COVID alone, there are 6 clinical studies dedicated to CBD. Not to mention, the other numerous pre-clinical and peer-reviewed journals of the same theme. 

With the spotlight ON again for CBD, one can’t help but wonder how CBD affects other respiratory issues.


The studies presented do not imply that CBD can treat the condition mentioned. Moreover, the information presented here is not meant as a substitute or alternative to information from healthcare professionals. 

Lung Fibrosis

Lung fibrosis is the thickening of the lung tissues making breathing difficult. Exposure to toxins, certain medical conditions, radiation therapy and particular medications increase the chance of lung fibrosis. 

Unfortunately, there is no single treatment that reverses the scarring damage a fibrosis gives but its symptoms can be managed. 

  • Steroids and immunosuppressants can suppress inflammation. 
  • Lifestyle change helps too. 
  • In severe cases, a lung transplant may be needed. 

Preventing inflammation is key in slowing or even stopping the progression of tissue scarring. With that background in mind, researchers began zeroing on CBD.

In a review published in 2021, they concluded that cannabinoids “affect the same pathways as other drugs currently used medicine in fibrosis treatment.”

The same review mused that the modulation of the endocannabinoid system, where some of the effects of CBD are majorly realized, should be considered for further investigation.

Bronchitis is a condition where the bronchial tubes that carry air into the lungs become infected.

The cannabinoids’ power to dilate bronchial passages has been observed in a 2013 study. There, they saw bronchodilation in humans that lasted for 15 minutes up to an hour.

A 2014 study by Gates et al., theorized that the dilation power of cannabinoids was due to the activation of CB1 receptors (part of a bigger system – the endocannabinoid system). 

There are several contrasting studies though. For example, a 2020 assessment on cannabis concluded that vaping among young adults causes bronchitis. 


COPD or Chronic Obstructive Pulmonary Disease refers to a group of lung diseases characterized by the chronic inflammation of the airways and the lungs. 

In a pre-clinical test of 2015 involving mice, CBD made breathing easier for the test subjects. 

Because smoking is one of the major causes of COPD, a small study in 2013 explored how CBD can help with quitting cigarette smoking. The volunteers under the CBD group smoked fewer cigarettes of less than 40 percent compared to the untreated group. 


Pneumonia is the infection of the lungs’ air sacs or alveoli. After infection, inflammation of the area ensues. 

Air sacs, located in both lungs, are tiny sacs where the exchange of oxygen and carbon dioxide happen. 

Symptoms of pneumonia may include cough, fever, shortness of breath, loss of appetite, nausea, confusion, among others. 

Through rounds of antibiotics, pneumonia can be treated without trouble if immediately attended to. 

Its symptoms gradually disappear as soon as treatment starts. Because there is readily available pneumonia treatment, the number of studies focusing on CBD’s effects on pneumonia is dire to zero.
