(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.

“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. About 47.4 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.
