This represents a decrease of approximately two-thirds since the CDC began collecting this data in 1965.
"This significant decline in smoking is the achievement of consistent and coordinated efforts by the public health community and our numerous partners," said agency director Dr. Robert R. Redfield in a statement Thursday. "Yet our work is far from over."
The report estimates that 49.1 million adults in the U.S., or nearly 1 in 5, used any tobacco product in 2018. Cigarettes were the most common 13.7%, followed by cigars, cigarettes, and a few filtered cigars that were used by 3.9% of adults.
E-cigarettes are the third most prevalent tobacco product used by adults, with 3.2%. Their use grew by 2.8% in 2017, although it declined several years earlier. This is due in part to the increase in vaping among young people between the ages of 18 and 24, which has jumped from 5.2% in 2017 to 7.6% in 2018.
Those most likely to use tobacco are between 25 and 44; members of certain minority groups, including adult lesbians, gay and bisexual; those living with disabilities or severe mental distress; people from the Midwest or South; and adults who earn less than $ 35,000 a year.
The report also found that cigarette smokers became more likely to try to quit in the previous 12 months and were more successful in doing so.
