development and implementation of major public education
and policy initiatives have driven down cigarette smoking
rates among U.S. adults from 42 percent in 1965 to 15 percent
in 2015 ( 20, 34). In addition, the most recent data show
declining use of cigarettes among high school students:
In 2011, 15. 8 percent of high school students were current
users of cigarettes, compared with 9. 3 percent in 2015 ( 38).
We have made tremendous progress reducing the public
health burden of tobacco use, with researchers estimating
that more than 8 million smoking-related deaths were
prevented in the United States from 1964 to 2014 as a result
of declines in cigarette smoking rates ( 39). The reductions
in cigarette smoking rates have not been evenly distributed
among all segments of the population, as defined by race,
ethnicity, educational level, socioeconomic status, and
place of residence ( 40). For example, 29. 2 percent of non-Hispanic American Indians/Alaska Natives, 18. 2 percent
of non-Hispanic whites, 17. 5 percent of non-Hispanic
blacks, 11. 2 percent of Hispanics, and 9. 8 percent of non-Hispanic Asians are smokers ( 40).
In addition, U.S. adult use of other tobacco products
that can cause certain types of cancer—cigars, smokeless
abruptly is more likely
to lead to lasting
than cutting down
gradually ( 36).
U.S. adults who smoke are
more likely to develop lung cancer
than those who do not; but those
who quit, cut their chance of dying
from lung cancer in half within
10 years ( 35).
BEYOND THE LUNGS:
CANCERS CAUSED BY SMOKING TOBACCO
Smoking tobacco increases an individual’s risk of
developing not only lung cancer, but also 17 other types
of cancer ( 34). No level of exposure to tobacco smoke is
safe, including exposure to secondhand smoke, which is
estimated to have resulted in more than 260,000 of the 5
million lung cancer deaths in the United States attributable
to smoking from 1965 to 2014 ( 35).
