The Food and Drug Administration (FDA or USFDA) is a federal agency of the United States Department of Health and Human Services, one of the United States federal executive departments. The FDA is responsible for protecting and promoting public health through the regulation and supervision of food safety, tobacco products, dietary supplements, prescription and over-the-counter pharmaceutical drugs (medications), vaccines, biopharmaceuticals, blood transfusions, medical devices, electromagnetic radiation emitting devices (ERED), cosmetics, animal foods & feed[5] and veterinary products.
The FDA was empowered by the United States Congress to enforce the Federal Food, Drug, and Cosmetic Act, which serves as the primary focus for the Agency; the FDA also enforces other laws, notably Section 361 of the Public Health Service Act and associated regulations, many of which are not directly related to food or drugs. These include regulating lasers, cellular phones, condoms and control of disease on products ranging from certain household pets to sperm donation for assisted reproduction.
The FDA is led by the Commissioner of Food and Drugs, appointed by the President with the advice and consent of the Senate. The Commissioner reports to the Secretary of Health and Human Services. The 21st and current Commissioner is Dr. Margaret A. Hamburg. She has served as Commissioner since May 2009.

As the safety and efficacy of e-cigs have not been fully studied, consumers of e-cigarette products currently have no way of knowing whether e-cigarettes are safe for their intended use, how much nicotine or other potentially harmful chemicals are being inhaled during use, or if there are any benefits associated with using these products.
Currently, e-cigarettes that are marketed for therapeutic purposes are regulated by the FDA Center for Drug Evaluation and Research (CDER). The FDA Center for Tobacco Products (CTP) . . . intends to regulate other nicotine-containing products, including electronic cigarette products that do not make a therapeutic claim, in the future.
FDA E-Cigarette Regulations Are Imminent
The fact that the proposed e-cigarette regulations were not handed down today should not be interpreted as the FDA backing down from regulating the industry, as it did in 2010. Given the growth of the e-cigarette consumer base and the amount of pressure the FDA is receiving from state legislatures demanding regulation, e-cigarette regulations are imminent and those engaged in the industry should prepare for dramatic changes in the way they conduct their operations.

FDA Regulation of e-Cigarettes
Only e-cigarettes that are marketed for therapeutic purposes are currently regulated by the FDA Center for Drug Evaluation and Research (CDER). Currently, the FDA Center for Tobacco Products (CTP) regulates
cigarettes,
cigarette tobacco,
roll-your-own tobacco, and
smokeless tobacco.
FDA has issued a proposed rule that would extend the agency’s tobacco authority to cover additional products that meet the legal definition of a tobacco product, such as e-cigarettes.
