Canadian Study Examining if Cannabis Combats the Coronavirus

It can be extremely difficult following all of the news regarding cannabis or the coronavirus. Both impact many aspects of our lives and news breaks literally every day on a number of fronts. It only took a matter of time before the two subjects converged.

On the heels of a couple of Israeli studies looking into whether cannabis can help combat the coronavirus, a Canadian study has issued some early promising findings about the ability of high-CBD extracts to help prevent and treat COVID-19. The study hasn’t been peer-reviewed and more studies certainly need to be done, so no one should consider it as gospel, but early results appear to be encouraging as CTV reported:

Researchers at the University of Lethbridge say while clinical trials still need to be done, data they’ve been collecting over the past four years shows promise that some cannabis extracts may help in the prevention and treatment of COVID-19.

Olga and Igor Kovalchuk have been working with cannabis since 2015, using varieties from around the world to create new hybrids and develop extracts that demonstrate certain therapeutic properties.


The Kovalchuks say, based on the preliminary data and pending further investigations, anti-inflammatory high-CBD cannabis extracts can modulate the levels of the receptors in highly relevant tissues, such as the mouth, lungs and intestinal cells.

The preliminary study states that:

 While our most effective extracts require further large-scale validation, our study is crucial for the future analysis of the effects of medical cannabis on COVID-19. The extracts of our most successful and novel high CBD C. sativa lines, pending further investigation, may become a useful and safe addition to the treatment of COVID-19 as an adjunct therapy. They can be used to develop easy-to-use preventative treatments in the form of mouthwash and throat gargle products for both clinical and at-home use. Such products ought to be tested for their potential to decrease viral entry via the oral mucosa. Given the current dire and rapidly evolving epidemiological situation, every possible therapeutic opportunity and avenue must be considered.

Of course, one should follow medical advice that doesn’t come from a health professional, so no one should think that they can just smoke cannabis, high-CBD or otherwise, and believe that they will be 100% safe from the coronavirus. However, it is nice to have some positive news about preventing or treating COVID-19, even if more research needs to be done. Fingers crossed that we find good medicines, whether from cannabis or anywhere else.
