That's clearly a strawman: nothing is a panacea. But here are some links from the first page of Google when I searched for "CBD research":
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4189631/
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4604171/
Each have dozens or more citations and are from reputable scientists at large universities. If your agenda is "the scientific method," hopefully that Google search helped.
We should regulate CBD so that salespeople don't make absurd claims about what it can or can't do. But claiming that it's on par with megadosing iodine or salt lamps is pretty uneducated.
