Despite strong evidence of the link between smoking and cancer by the early 1950s, the Surgeon General did not issue a statement linking smoking to health risks until 1964—a decade after the TIRC was formed.23 The following year, Congress passed a bill requiring a health warning on tobacco products. But it was not until 1970 that cigarette advertising was curtailed at the federal level, and not until 1992 that the sale of tobacco products to minors was prohibited.
