Final answer:
The FDA has jurisdiction over a variety of products including cigarettes, prescription drugs, artificial hearts, and aspartame. Tobacco products are explicitly under FDA regulation as are medical devices and prescription meds.
Step-by-step explanation:
The FDA (Food and Drug Administration) has jurisdiction to regulate many products aimed at ensuring public health and safety. These include tobacco products, like cigarettes, prescription drugs, medical devices such as artificial hearts, and substances added to food, such as the sweetener aspartame used in products like Nutra-Sweet.
The FDA is responsible for overseeing the safety, efficacy, and security of many products that affect American lives daily, but this oversight doesn't apply without limits. In recent years, questions have arisen about the FDA's role in regulating products such as e-cigarettes, which are often marketed as safer alternatives to cigarettes, although this is still a topic of ongoing discussion and legislation.
