(CNN) Cigarette smoking among US adults fell to its lowest recorded level in 2018: 13.7%, according to a report published Thursday by the US Centers for Disease Control and Prevention.

That represents a drop of roughly two-thirds since the CDC started collecting this data in 1965.

"This marked decline in cigarette smoking is the achievement of a consistent and coordinated effort by the public health community and our many partners," the agency's director, Dr. Robert R. Redfield, said in a statement Thursday. "Yet, our work is far from over."

The report estimated that 49.1 million US adults, or nearly 1 in 5, used any tobacco product in 2018. Cigarettes were the most common at 13.7%, followed by cigars, cigarillos and little filtered cigars, which were used by 3.9% of adults.

E-cigarettes were the third most common tobacco product used by adults, at 3.2%. Their use rose from 2.8% in 2017, despite having been on the decline for several years prior. This was attributed partly to increases in vaping among young adults 18 to 24, which jumped from 5.2% in 2017 to 7.6% in 2018.
