27 July 1965: President Johnson signed a bill requiring cigarette
makers to print health warnings on all cigarette packages about the
effects of smoking.
The landmark Surgeon General's report from 1965 on smoking and health stimulated a
greatly increased concern about tobacco on the part of the American
public and government policymakers and led to a broad-based anti-smoking
campaign. It also motivated the tobacco industry
to intensify its efforts to question the scientific evidence linking
smoking and disease. The report was also responsible for the passage of
the Cigarette Labeling and Advertising Act of 1965, which, among other things, mandated Surgeon General's health warnings on cigarette packages.
