Moreover, the rise and fall of smoking-caused diseases and premature deaths during the twentieth century generally follow patterns of changing tobacco-use behavior, albeit several decades later. Although there had been previous statements on the harms of using tobacco, the report was significant for providing the most thorough and comprehensive review up to that time.

However, translating this knowledge into action to benefit public health was not a simple or direct process. At the time of release of the report, the tobacco industry had a powerful influence and attempted to minimize the impact of the report using a broad set of strategies Kluger ; Brandt ; Proctor That influence has now greatly declined, diminished by many factors, including trends in American culture, politics, economics, health care, and social life.

This chapter addresses how the evolving scientific evidence on tobacco has been a key driver of the changes that have led to a dramatic shift in social norms around cigarette smoking.

These changes have been driven by many factors, including patterns of tobacco use across the twentieth century to the present. Mortality from cardiovascular diseases CVD dropped sharply and progressively, and rates for a number of cancers peaked and began to decline, most notably in men.

By contrast, mortality from chronic obstructive pulmonary disease steadily climbed. Changes in the prevalence of tobacco smoking contributed to these shifts, but patterns of other risk factors also changed over the last 50 years, as programs addressed hypertension and other risk factors for CVD, and medications became available that reduced CVD, such as statins Feinlieb et al.

And unrestricted tobacco advertising, often with health-related claims, was seen as taking unfair advantage of those who were most vulnerable.

In the first two decades of the century, an organized antitobacco effort developed, composed of temperance advocates, religious leaders, and health reformers Kluger They were alarmed by the increase in cigarette smoking among youth and believed it to be associated with the abuse of alcohol and narcotic drugs.

Cumming warned about the hazards of tobacco claiming that excessive smoking caused nervousness, insomnia, and other ill effects in young women Burnham Like many physicians at the time, he believed that women were more susceptible than men to certain injuries, especially of the nervous system.

But Cumming, a smoker, distanced himself from the more extreme antitobacco and temperance reformers of the time Parascandola Although physicians generally did not see a significant health threat for most smokers, there was growing concern over cigarette advertising during the s and s that made a wide array of unfounded health claims.

In the highly competitive branded cigarette market, prominent advertising campaigns included explicit health claims: FTC brought legal action against each of the major cigarette companies during the s in an effort to curb health claims in advertising, resulting in a series of cease-and-desist orders.

By the s, however, American scholars and activists had become aware of increasing cancer death rates.
