Did a study find that a cannabis compound helped prevent SARS-CoV-2 from infecting cells?

Researchers from Oregon State University observed that two cannabis compounds, CBGA (cannabigerolic acid) and CBDA (cannabidiolic acid), are able to block SARS-CoV-2 from entering cells. By attaching themselves to spike proteins on the virus, the compounds block an important step in the infection process.

This does not mean smoking weed will prevent COVID-19. The purity of the tested compounds was higher than that available in commercial products. In a separate study, THC (tetrahydrocannabinol), the psychoactive component of cannabis, did not keep the virus out of cells, and even blocked the therapeutic effect of CBD when combined with the non-psychoactive compound.

Scientists emphasize that more research must be done to corroborate the findings.

Between 2020 and 2022, under close editorial supervision, Gigafact contracted a group of freelance writers and editors to test the concepts for fact briefs and provide inputs to our software development process. We call this effort Gigafact Foundry. Over the course of these two years, Gigafact Foundry writers published over 1500 fact briefs in response to claims they found online. Their important work forms the basis of Gigafact formats and editorial guidelines, and is available to the public on Gigafact.org. Readers should be aware that while there is still a lot of relevant information to be found, not all fact briefs produced by Gigafact Foundry reflect Gigafact's current methods and standards for fact briefs. If you come across any that you feel are out of date and need to be looked at with fresh eyes, don't hesitate to contact us at support@gigafact.org.
