I understand you have some concerns, but it’s not like people doing cutting edge drug research don’t know how to do research.

Large drug companies are not bringing magic recipes to the mix here. Often it’s the same researchers who found the drug who end up starting drug a company to profit from their research.

As to advertising to doctors their is plenty of evidence this is harmful. It’s easy to for doctors to keep up with relevant drugs as so few are added each year and many are extremely specialized. Advertising results in over prescription which is known to be extremely harmful with opioids being an obvious example.
