No evidence: A scientific study shows that cannabis is more effective at preventing and treating COVID-19 than hydroxychloroquine.

Explanation: The World Health Organization recognizes some therapeutic uses of cannabinoids. A recent scientific preprint reported that some cannabis strains might modulate the expression of ACE2, the viral receptor for SARS-CoV-2, in an in vitro study. However, the study does not present data on clinical outcomes in animals or humans (in vivo) during infection, nor does it test whether the cannabis extracts affect the infectivity of SARS-CoV-2. It is thus impossible to know whether these specific cannabis strains could prevent or cure COVID-19 in people. The study also did not compare the effect of cannabis extracts with that of hydroxychloroquine on COVID-19, so it does not provide any evidence for the claim that cannabis works better than hydroxychloroquine.
