Medical Cannabis

Are you wondering what is actually meant by medical cannabis?

What is the relation between the cannabis plant and cough?

To your ease, medical cannabis is another name for medical marijuana. It helps to treat different body conditions along with cough. It originates in the marijuana plant, which possesses several chemicals that work differently.

However, two of these chemicals are used in medicine. Namely:

  • Cannabidiol (CBD)
  • Tetrahydrocannabinol (THC)

How is Medical Marijuana different from the Cannabis Sativa plant?

CBD stands for Cannabidiol which is a chemical substance present in the Cannabis Sativa plant. This chemical extract shows many therapeutic effects. So this is why it is called Medical marijuana.

You might be thinking of how cannabis can help treat a health condition; Cannabidiol is different from marijuana. Also, CBD does not cause hallucinations. Moreover, people have commonly used this substance as a medicinal agent for millennia (originated from Asia).

More recently, scientists are experimenting and researching more on this still-mysterious substance that might be an FDA-approved medication one day. Cannabidiol in managing in-patient cannabis withdrawal: clinical case series | can help you explore CBD comprehensively.

There is not much evidence supporting the treatment of a cold by CBD while treating other symptoms that occur during a cold.

Dr. David Allen, a leading CBD researcher member of the International Cannabinoid Research Society (ICRS), says,

Does Marijuana Help with Cough?

Yes, research shows that it helps recover from cough. However, keep in mind, do not vape or smoke it. Instead, marijuana is most effective as an edible item. It works by opening the airways and relaxing the muscles of the lungs (bronchodilator).

Does Cannabis Help with COVID-19?

Cannabis can fight against COVID-19, as per a recently published study. According to this research, two of the components, CBD and 7-OH-CBD (metabolite), can stop COVID-19 infection. Moreover, it can block the infection at both stages, either early or later.  

Furthermore, symptoms during COVID-19 such as inflammation and pain can also be relieved through medical marijuana. 

Is there a Treatment with Cannabis for Cough?

What Studies Tell Us about Medical Marijuana

1. Medical Cannabis for Cough

A few research studies show some pieces of evidence for the efficacy and effectiveness of CBD oromucosal spray in symptom management of cough patients. Moreover, it provides comfort by relaxing muscles, reducing inflammation or irritation, lowering the inflated response in the air tubes, and widening the bronchi of the lungs. 

Additionally, using other natural substances that aid cough with CBD can decrease the recovery time. However, you must consult a doctor before taking it because it might interact with some medications.

2. Medical Cannabis for COPD

Interestingly, this CBD Oil for COPD: How to Use This Cannabinoid Oil & Dosage Study can answer all the questions you are thinking about as a COPD patient.

During COPD, narrowing in the airways can be observed, so CBD has greater chances to broaden or dilate these airways. Specifically, CBD is associated with helping create better airflow in the lungs. Hence, proving it to be a bronchodilator.

Additionally, an animal trial in 2014 indicates improvement in the functioning of lungs and reduction in inflammation.

3. Medical Cannabis for COVID-19

Consider this mind-blowing study (In Search of Preventative Strategies: Novel Anti-Inflammatory High-CBD Cannabis Sativa Extracts Modulate ACE2 Expression in COVID-19 Gateway Tissues). Specifically, this study hints at an increased potential of Cannabidiols to recover from COVID-19. 

Additionally, it would be a substantial achievement if it were replicated and verified by more rigorous trials.

4. Medical Cannabis for Asthma

Good news for asthma patients: Cannabidiol reduces airway inflammation and fibrosis in experimental allergic asthma.

Firstly, it reduces airway hyperresponsiveness (higher airway sensitivity). Additionally, it provides you strength against frequent asthma triggers or flare-ups.

Antioxidant and anti-inflammatory properties possessed by medicinal cannabis might also aid in improving the immune system. Therefore, coughing and other asthma-related symptoms will improve as well.

Still, experts suggest more research on CBD in humans. 

5. Medical Cannabis for Other lung diseases

Respiratory patients could benefit from the properties mentioned above and benefit from this plant-based substance to treat other lung disorders.

Researchers also expect it to be a part of future anti-viral medications. Namely, specific experiments still need to be done to yield sufficient knowledge for treating several other respiratory system-related diseases.

  1. Hi there! My father-in-law has been dealing with occasional asthma attack since last month and he has been searching for suitable alternative treatments. It’s really interesting to know that medical cannabis can help prevent our airway from becoming overly sensitive. I’ll definitely ask him to consider this option when he makes an appointment with an expert soon.

    • Hi Amy, thanks for reaching out.
      It is helpful to consider all of the available options, especially those supported by rigorous scientific research.
      We wish good health for your father-in-law.
