What was the importance of the 1938 Food, Drug, and Cosmetic Act in the U.S.?

The significance of the 1938 Food, Drug, and Cosmetic Act lies in its requirement for proof of safety and effectiveness for drugs before they could be marketed. This legislation emerged in response to public health concerns following incidents of dangerous and untested products being sold, such as the tragic case of the elixir sulfanilamide, which led to numerous deaths. By mandating that pharmaceutical companies demonstrate the safety and efficacy of their drugs, the Act aimed to protect consumers from harmful substances and ensure that they received safe and effective treatments. This marked a pivotal shift in regulatory practices, establishing a framework for drug approval that persists in various forms to this day.

While aspects such as nutrition and agricultural subsidies are important, they are not directly addressed by this legislation. This Act primarily targeted drug safety and efficacy, revolutionizing the way health products were regulated in the U.S.
