RFK Jr has been talking about this; I listened to an in-depth interview with him that included a long discussion about the prescribing of Ozempic. He said terrible things about it all — like the advertising and the incentives for doctors to prescribe it and the potential side-effects.
The interview was the one RFK Jr had with Tucker Carlson. It did not come up when I searched for RFK Jr interview! But if you search with both names it will come up.
