It was not the first such report but it is probably the most famous because it kick-started a global campaign to reduce the levels of smoking and the deaths it causes.
In the 50 years since then, the patterns of smoking all over the world have changed dramatically. In the U.S., the numbers of smokers peaked in 1965 and have fallen precipitously since then. Similar patterns have occurred in all industrialized countries.
