According to a peer-reviewed paper published this week in the Journal of Natural Products, titled "Cannabinoids Block Cellular Entry of SARS-CoV-2 and the Emerging Variants," at least three compounds naturally occurring in the cannabis plant were shown in lab tests to be effective at stopping coronavirus molecules from entering human cells.

With widespread use of cannabinoids, resistant variants could still arise, but the combination of vaccination and CBDA/CBGA treatment should create a more challenging environment with which SARS-CoV-2 must contend, reducing the likelihood of escape.
