Data from the CDC indicate that there has been no statistically significant change in the prevalence of adult smoking between 2010 (19.3%) and 2011 (19.0%). However, the proportion of those who smoked 30 or more cigarettes per day declined from 12.6% in 2005 to 9.1% in 2011. The findings are available for free online at www.cdc.gov/mmwr.
