• Gio Batta Gori - The Bogus 'Science' of Secondhand Smoke 

In reality, it is impossible to summarize accurately from momentary and vague recalls, and with an absurd expectation of precision, the total exposure to secondhand smoke over more than a half-century of a person's lifetime. No measure of cumulative lifetime secondhand smoke exposure was ever possible, so the epidemiologic studies estimated risk based not only on an improper marker of exposure, but also on exposure data that are illusory.

Adding confusion, people with lung cancer or cardiovascular disease are prone to amplify their recall of secondhand smoke exposure. . . .

It has been fashionable to ignore the weakness of "the science" on secondhand smoke, perhaps in the belief that claiming "the science is settled" will lead to policies and public attitudes that will reduce the prevalence of smoking. But such a Faustian bargain is an ominous precedent in public health and political ethics. Consider how minimally such policies as smoking bans in bars and restaurants really reduce the prevalence of smoking, and yet how odious and socially unfair such prohibitions are. .. .

A frank discussion is needed to restore straight thinking in the legitimate uses of "the science" of epidemiology ¿ uses that go well beyond secondhand smoke issues. Today, health rights command high priority on many agendas, as they should. It is not admissible to presume that people expect those rights to be served less than truthfully.
