Cannabis Inhibits SARS-CoV-2 Replication in Human Lungs, Study Suggests


With the SARS-CoV-2 virus causing almost 3 million deaths worldwide, researchers have been scrambling to learn more about the deadly COVID-19 disease that has threatened global public health and world economies.

A new study, published on preprint server bioRxiv last week, suggests that a cannabis plant compound inhibited infection with SARS-CoV-2 in human lung cells.

According to the researchers at the University of Chicago in Illinois, cannabidiol (CBD), a chemical in the Cannabis sativa plant, also known as marijuana, and its metabolite 7-OH-CBD, blocked SARS-CoV-22 replication in lung epithelial cells. Epithelial cells are cells that come from body surfaces, such as the skin, blood vessels, urinary tract or organs.

The researchers also found that CBD appeared to inhibit viral gene expression and reverse many of the effects SARS-CoV-2 has on host gene transcription. CBD also appeared to bring about the expression of interferons, proteins released by cells, in response to the entry of viruses, that are supposed to inhibit virus replication. In addition, for those patients who had been taking CBD, the incidence of SARS-CoV-2 infection was up to an order of a magnitude lower than in patients who had not been taking CBD.

“This study highlights CBD, and its active metabolite, 7-OH-CBD, as potential preventative agents and therapeutic treatments for SARS-CoV-2 at early stages of infection,” lead author Marsha Rosner and her colleagues told News Medical.

This is not the first time that scientists have suggested that CBD may help prevent COVID-19.

According to Dr. Frank Lucido, a family practice physician who works with medical cannabis patients, CBD can potentially reduce cytokines, which are substances secreted by cells of the immune system as part of the body’s natural immune response.

“CBD looks promising in reducing the cytokine storm, which seems to be the most damaging aspect of COVID-19 infection,” Lucido told the San Francisco Chronicle in September 2020.

In a peer-reviewed article published in the journal Brain, Behavior and Immunity, researchers from the University of Nebraska and the Texas Biomedical Research Institute also said CBD decreased SARS-CoV-2 induced lung inflammation, and also prohibited cytokine production by immune cell.

  1. Everyone around me is strung out on some sort of pharmaceutical much of that is due to this so called “medical” marijuana. this drug driven agenda is nonsense as they begin now legalizing everything under the sun!! The ONLY purpose for the recreational drug proliferation is to develop an acceptance and allowance in order to cause these individual’s independent thought to become incapacitated and their intellectual integrity compromised.

    side note: This is just a conveniently timed legalization for items that never should have been “illegal” to begin with but hey they profited big time off the illegality of it!

    1. Now by God, if this isn’t talking out of both sides of your mouth I don’t know what is.
      Cannabis has saved more lives from cancer than may ever be known, and as far as a recreational drug, the elitists who conducted the Revolutionary War, Mexican American War, the Civil War, the Spanish American War, WWI, WWII, the Korean War, and Vietnam, and every war since have all been a bunch of f-king drunks.
      It has been my experience that LSD takes a back seat to alcohol and is right up there with PCP when taken in sufficient quantity.
      But you are right. There has never been any authority for our servants to tell us what we can and cannot put in our bodies.
      A clear mind is always a good thing to have when planning tactics, but in hand to hand combat to the death or just plain street fighting, the proper amount of alcohol can give you an edge.
      I guess buzzed is in the body of the beholder.

  2. This is how a plandemic should go, a 99.8% survival rate and all you have to do to stay healthy is smoke dope and drink gin & tonics.
