This analysis complemented earlier work that has documented decreasing intensity of cigarette use among young people, for example the finding by Jones et al. (2011) that among current cigarette smokers, the frequency of light smoking (< 1–5 cigarettes per day) had increased significantly from 1991–2009, while for heavy smoking (> 11 cigarettes per day) the frequency had more than halved.
1997: 25%; 2012: 18%
Eighteen percent of American adults were cigarette smokers in 2012, according to a report released last week by the National Center for Health Statistics, down from 18.9 percent the previous year. From 2009 to 2012, the rate dropped to 18 percent from 20.6 percent, the first statistically significant change over multiple years since the period spanning 1997 to 2005, when the rate fell to 20.9 percent from 24.7 percent.
