Food and Drug Administration (FDA)

Many ads have been appearing on t.v. lately, showing the adverse side affects of drugs many Americans have used. Then we see the follow on ads by lawyers offering their services to "loved ones" and other family members who have suffered the dire affects. There is something wrong here. What is the purpose of the Food and Drug Administration (FDA)? Isn't it to test, monitor, and approve a drug safe for the American public to use? Then why are we witnessing so many recalls? I would assume there are a litany of tests that a new drug would be subjected to before it is deemed safe to use. But with all the recalls, one has to wonder what is going on. There is something terribly wrong with this picture. Could it be there is some type of collusion going on between Big Pharma, the FDA and lawyers, at the expense of the American people? Someone needs to look into this.
