Pseudoscience tobacco advertising from the bad old days

These first two advertising pieces claim at the same time that the tobacco brand (Camel and Old Gold) they sell is the best, inasmuch as alleged surveys have suggested that the social sector of health professionals -including those specialized in the care of the throat- have shown to prefere the brand of each advertisement in both cases. Basically, what this means is that the majority of doctors clearly liked and/or consume a single cigarettes brand the most, but this first place in preference is occupied by at least two brands at the same time! This is an explicit incongruence.

The third piece of advertisement has also resorted to a scientific appearence, for the lack of evidence has repeated itself in this case as well. The brand prides itself in discarding out of their product a substance which is said to cause irritation, however it was thought to be at the same time "indispensable to cigarette manufacture". The content of the ad talks about this modification as a wonderful achievement, although the reason for this is not explicit. Nevertheless, it is also written in conveniently small letters what the main content never made clear: "Philip Morris & Company do not claim that Philip Morris Cigarettes cure irritation. But they do say that an ingredient--a source of irritation in other cigarettes--is not used in the manufacture of Philip Morris."

So if the cigarettes of this brand do not cease to be irritating, why is it important to mention that an irritating substance was taken out of the formula? And, if the modification made a real important difference on health for positive, wouldn't advertisers be glad to comunicate the scientific evidence, the irrefutable facts? This does not guarantee, for example, that heretofore was not replaced by another ingredient as harmful as the last, knowing that it was thought to be indispensable.
