The problem is that medical journals and most mainstream media outlets rely heavily on pharmaceutical advertising. The general public does not get an accurate assessment of the risks of the drugs. Nor are adequate safety trials done, again, because the only funding available is from the drug companies themselves.
The risk assessment argument is also fallacious with regard to vaccines, which are often mandated as a condition of employment or school attendance. I should be able to insist on complete safety for a medication that is being forced on me.
Isn't it our tax dollars that fund the research that goes into developing these drugs? How many years of research (and how many millions of dollars) for each medication do we flush when we take the drugs off the market all because a small percentage of users had adverse reactions or died?
Researchers work very hard for years to develop a drug to benefit the greatest number of people who are in real pain and discomfort. They cannot guarantee a benefit to all.
