However, further study on CBD delivery mechanisms, CBD concentrations, and ideally administration of CBD in a prospective, randomized trial are needed to further explore this finding and its clinical applicability.&#8221;<\/p>\n<p>Rosner called her group&#8217;s discovery regarding CBD&#8217;s potential as a COVID fighter &#8220;complete serendipity.&#8221; She&#8217;s a cancer biologist, and knew about CBD because of its anti-inflammatory effects.<\/p>\n<p>Since most of the damage done by a COVID-19 infection stems from the human immune system&#8217;s overreaction to the virus, Rosner and her colleagues thought CBD might help prevent <a href=\"https:\/\/my.clevelandclinic.org\/health\/symptoms\/21660-inflammation\" target=\"_blank\" rel=\"noopener\">inflammation <\/a>from harming the lungs and other organs in the body.<\/p>\n<p>Instead, lab tests showed that CBD directly inhibited the virus&#8217; ability to replicate, stopping its spread in human cells. Mice treated with CBD for one week were able to suppress COVID-19 infection in their lungs and nasal passages.<\/p>\n<p>&#8220;We just wanted to know if CBD would affect the immune system,&#8221; Rosner said in a University of Chicago news release. &#8220;No one in their right mind would have ever thought that it blocked viral replication, but that&#8217;s what it did.&#8221;<\/p>\n<p>To see whether CBD has any real-world potential, the research team analyzed data from 1,212 epilepsy patients prescribed Epidiolex.<\/p>\n<p>People taking Epidiolex were 35% to 52% less likely to suffer a COVID-19 infection than an equal number of folks from a control group not prescribed the drug, according to data drawn from the federally funded National COVID Cohort Collaborative.<\/p>\n<p>The findings were published Jan. 20 in the journal <a href=\"https:\/\/www.science.org\/doi\/10.1126\/sciadv.abi6110\" target=\"_blank\" rel=\"noopener\"><em>Science Advances<\/em>.<em><\/em><\/a><\/p>\n<p>The researchers believe that CBD fights COVID-19 by prompting cells to release <a href=\"https:\/\/www.webmd.com\/drug-medication\/interferons-guide#1\" target=\"_blank\" rel=\"noopener\">interferon<\/a>, a biochemical that sabotages the ability of viruses to replicate in cells, Rosner said.<\/p>\n<p>&#8220;We showed that CBD increases the amount of this [interferon] factor, and if you block that factor from acting, you actually counteract the effect of CBD and now the virus can replicate again,&#8221; Rosner said.<\/p>\n<p>CBD doesn&#8217;t affect the ability of the coronavirus to enter cells. Rather, it blocks replication of the virus after it&#8217;s already entered cells, the researchers reported.<\/p>\n<p>However, it&#8217;s likely that people will need high blood levels of CBD for this to work, Rosner said. That&#8217;s where the purity, dosage and type of CBD treatment comes into play.<\/p>\n<p>&#8220;The way CBD is formulated really determines how much can get into the blood,&#8221; Rosner said. &#8220;If it&#8217;s introduced as an oil, it&#8217;s not very water-soluble and often will go to the liver and get metabolized and broken down. You have to make sure there&#8217;s enough in the blood for it to be active.&#8221;<\/p>\n<p>Don&#8217;t think you can smoke weed and get enough CBD to protect yourself that way, either. You won&#8217;t absorb enough CBD from the smoke, and you&#8217;ll also get too much <a href=\"https:\/\/www.webmd.com\/pain-management\/cbd-thc-difference\" target=\"_blank\" rel=\"noopener\">THC<\/a>, the compound in pot that gets you high, Rosner said.<\/p>\n<p>&#8220;We tested THC. It does not work. Furthermore, when we added THC to CBD, it prevented CBD from blocking the replication of the virus,&#8221; Rosner said.<\/p>\n<p><strong>More information<\/strong><\/p>\n<p>The U.S. National Institutes of Health has more on <a href=\"https:\/\/www.covid19treatmentguidelines.nih.gov\" target=\"_blank\" rel=\"noopener\">COVID-19 treatments<\/a>.<\/p>\n<p>SOURCES: Marsha Rich Rosner, PhD, professor, cancer research, University of Chicago; Amesh Adalja, MD, senior scholar, Johns Hopkins Center for Health Security, Baltimore; <em>Science Advances<\/em>, Jan. 20, 2022<\/p>\n<div class=\"around-the-web\">\n<p>Related Articles Around the Web<\/p>\n<\/p><\/div>\n","protected":false},"excerpt":{"rendered":"<p>MONDAY, Jan. 24, 2022 (HealthDay News) &#8212; Cannabidiol, a compound derived from marijuana, appears to show promise in blocking replication of the COVID-19 virus and preventing its spread, lab and animal studies show.
