"how physicians prescribe medicines" is in my opinion a bit shitty way to describe it to be honest, because there's also the whole scale from outright fraud and pushing addiction, all the way to offering a specific type of what would be prescribed anyway. (With pharmacies offering substitutes and generics)

There are also regions which try to counteract this with, for example, forcing prescriptions to list the active ingredient rather than a brand of medication. (with fun sideeffects like meningitis vaccine taking ~6 lines to describe)

"We have serious problems with pharma influence" - yes. "how physicians prescribe medicines" - unless you qualify that with more information - it's FUD.
