My wife is a doctor she’s never been paid by a pharmacy company.
It’s illegal to directly pay doctors for prescribing drugs. Pharmaceutical companies do pay some doctors for speaking gigs (a very small fraction of them).
The average doctor might get lunch in exchange for listening to a presentation. But I guarantee they aren’t there listening to a boring presentation because of a few dollars worth of food.
All these payments are public record, so you can look them up for any given doctor.
