I really wish that paper had an animal model for the effects stated. I woulld be interested in seeing if the pharmacokinetics of the cannabinoid acids allow for clinically significant effects in respiratory tissues.I may be proven wrong by science because there is some overlap in the ace2 receptors but in my opinion Canabis use is not a silver bullet vs covid or being anymore helpful than an asprin is. Maybe some relief but not an antiviral contender, I want to be wrong on this but I can't see it.o
Experiments cell lines are good for illustrating effects, but do not capture a lot of the nuances of whole organisms.
