Adult smoking rates have dropped from 42% in 1965 to 21.3% today, but the rate of decrease is slowing, according to the Centers for Disease Control and Prevention’s (CDC’s) Morbidity and Mortality Weekly Report (MMWR). The report also found use of cigars and smokeless tobacco products remains unchanged.

Meanwhile, use of electronic cigarettes, or e-cigarettes, is rising rapidly. The number of adults who smoked traditional cigarettes and said they had tried e-cigarettes doubled from 10% in 2010 to 21% in 2011, the CDC reports. The number of high school students who reported ever using an e-cigarette also rose from 4.7% in 2011 to 10% in 2012.

This MMWR report provides the most recent national estimates of tobacco use among adults 18 years old or older, using data from the 2012–2013 National Adult Tobacco Survey. The survey assessed use of the following tobacco products: cigarettes, cigars/cigarillos/filtered little cigars, regular pipes, water pipes/hookah, e-cigarettes, chewing tobacco/snuff/dip, snus (oral snuff), and dissolvable tobacco products.

The findings indicate that 21.3% of US adults used a tobacco product every day or some days, and that number rises to 25.2% when those who used a tobacco product every day, some days, or rarely are included. Of those 21.3%, 73.4% in this group used 1 or more tobacco products daily.

Prevalence of use of specific tobacco products every day or on some days was as follows: cigarettes, 18.0%; cigars/cigarillos/filtered little cigars, 2%; regular pipes, 0.3%; water pipes/hookah, 0.5%; e-cigarettes, 1.9%; and smokeless tobacco, 2.6%.
