Title 15 › CHAPTER 2 — FEDERAL TRADE COMMISSION; PROMOTION OF EXPORT TRADE AND PREVENTION OF UNFAIR METHODS OF COMPETITION › SUBCHAPTER I — FEDERAL TRADE COMMISSION › § 55
Defines key words used in sections 52 to 54. False advertisement means any ad (not labeling) that misleads in an important way. You judge that by what the ad says or shows and by what important facts it leaves out, including likely results from using the product as the ad describes or as normally used. Drug ads sent only to medical professionals are not false if they contain no false material facts and each copy includes a truthful, quantitative list of ingredients. Ads for oleomargarine or margarine are misleading if they claim the product is a dairy product, unless the ad gives a full and truthful list of ingredients. Food means things people or animals eat or drink, chewing gum, and ingredients of those items. Drug covers four groups: items in official drug books, things meant to diagnose, cure, treat, or prevent disease, nonfood items meant to change body structure or function, and components of those items; it does not include devices. Device (except in the ad rule) means tools, machines, implants, in vitro reagents, or similar articles used to diagnose or treat disease or affect the body, and that do not work mainly by chemical action in or on the body and are not dependent on being metabolized. Cosmetic means products applied to the body to clean, beautify, make attractive, or change appearance, or their components, but not soap. Oleomargarine or margarine includes all products called oleomargarine or margarine and any butter-like products made with non-milk fats to imitate butter.
