Advertising does not attempt to tell the truth, but to give a biased view of a product. Companies spend millions of dollars a year on advertising, and would not do so if there were no return on this investment. While purchasing a particular brand of cola on the basis of an advert might not be disastrous for the consumer, using an inappropriate drug could be.  Drugs companies have also shown their willingness to abuse their advertising rights. For instance the FDA has recently had to insist that the possible side effects of drugs must be listed as an integral part of TV advertisements, because advertisements were being produced in which the list of side effects was read at too fast a pace to be understood.  It is thus understandable that in a survey soon after the 1997 regulations on direct to consumer advertising, 80% of American Medical Association (AMA) General Practitioners (GPs) thought it was not a good idea and undermined their role.
