I think that both Wadio and his/her critics are correct. Wadio is correct in that if you push to get a prescription drug that you heard about on a radio advertisement and it turns out that you as an individual are allergic to chemicals in that prescription medicine--an allergy that you didn't know about until you took that prescription drug--the consequences for you as an individual could range from mild allergic reactions to death. So, having a ban on prescription drug advertisements over radio and TV might save some lives.
But it also might not. Pharmaceutical companies actually advertise their prescription medicines on both ends; that is, they advertise to consumers through radio and television and they advertise to doctors through various medical journals and by personal visits by salespeople from the major drug companies to those doctors. The proposed ban would only take consumer advertising off the table for those drugs *but not* the advertising to medical practitioners. As a consumer, you still might end up receiving a prescription for a medication that you are allergic to because not even your doctor knows that you have the allergy in the first place.
So, if I were in Senator Sanders' or RFK's shoes and I wanted to promote safer habits among pharmaceutical companies, doctors, and consumers, I think that I would raise the stakes by holdin the stockholders of pharmaceutical companies accountable for any spikes in severe allergic reactions, including death, that a specific prescribed medication caused.
Of course, that has two sides. Allergies can come from the individual's DNA structure; similar reactions can occur if you are taking prescribed medications that actually counteract each other due to different illnesses which you may be suffering at the same time. And, of course, such a law might make pharmaceutical companies less likely to develop new prescription medications out of fear of being sued if the new drugs either cause severe allergic reactions or even death in some individuals.
So even my proposal to fix the system would have issues, and, unless a substantial number of people are having severe reactions to prescription drugs, regardless of how they heard about them, I would probably recommend leaving the current system alone with maybe some tinkering around the edges to ensure drug safety.
