     "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 add to beauty or desirability.

     Often such products are nothing more than moneymaking things for their promoters.The results 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 and Drug

Administration)can require proof under the Food,Drug,and Cosmetic Act that is safe and effective before

it is put on the market.But if the product is a device,FDA has no authority to require premarketing proof

of safety or effectiveness.If a product already on the market is a 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,which had been

sold for reducing the waistline.The Relaxacisor produced electrical shocks to the body through contact

pads.FDA took legal action against the distributor to stop the sale of the device on the grounds that it

was dangerous to health and life.

     Obviously,most of the devices on the market 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 judge the safety or

effectiveness of such items.
