     "In only six days I lost seven pounds of weight."

     "Two full inches in the first three days!"

     These are the kinds of statements used in magazine, newspaper, radio and television ads, promising new

shapes and new looks to those who buy the medicine or the device. The promoters of products say they can

shape the legs, slim the face, smooth wrinkles, or in some other way to beauty or desirability.

     Often such products are nothing more than money-making things for their promoter. Where they produce

are questionable, and some are dangerous to health.

     To understand how these products can be legally promoted to the public, it is necessary to understand

something of the laws covering their regulation. If the product is a drug, FDA (Food Drug Administration)

can require proof (证明) under the Food, Drug, and Cosmetic Act that safe and effective before it is put on

the market. But if the product is a device, FDA has no author to require premarketing proof of safety or

effectiveness. If a product already on the marker danger to health, FDA can request the producer or distributor

to remove it from the market voluntarily, or it can take legal action, including seizure (查封) of the product. 

     One notable case a few years ago involved an electrical device called the Relaxacisor, had been sold for

reducing the waistline. The Relaxacisor produced electrical shocks to the customers through contact pads.

FDA took legal action against the distributor to stop the sale of the products to the grounds that it was

dangerous to health and life.

     Obviously, most of the devices on the maker have never been the subject of court proceedings (法律诉讼),

and new devices appear continually. Before buying, it is up to the consumer to the safety or effectiveness of

such items.
