(CNN) Cigarette use among American adults is at the lowest it's been since the Centers for Disease Control and Prevention started collecting data on the issue in 1965, according to a report released Thursday.

47.4 million Americans, or 19.3%, used any tobacco product in 2017, the report says. "The good news is that cigarette smoking has reached unprecedented lows, which is a tremendous public health win, down to 14 percent from over 40 percent in the mid-1960s," said Brian King , senior author of the report and deputy director for research translation at the CDC's Office on Smoking and Health. About47.4 million Americans, or 19.3%, used any tobacco product in 2017, the report says.

He believes that the decline is due to proven interventions, such as smoke-free policies and rises in the price of tobacco products.

As stated in the report, the data is from the National Health Interview Survey, "an annual, nationally representative, in-person survey of the noninstitutionalized U.S. civilian population." The 2017 sample included 26,742 adults and had a response rate of 53%.

Researchers assessed the use of five types of tobacco products: cigarettes, cigars, pipes (including water pipes and hookahs), e-cigarettes and smokeless tobacco (such as snuff or dip).
