The results are based on a national health survey of 27,000 US adults conducted by the Centers for Disease Control and Prevention in 2017.
Smoking prevalence has declined significantly since the 1960s. Roughly 42 per cent of US adults were smokers in the early 1960s, New York Times reported. Smoking has declined by 2 per cent since 2016, according to the report.
K. Michael Cummings of the tobacco research program at Medical University of South Carolina commented on the findings. He said that although there has not been a steep decline in smoking prevalence over the last two years, there has been a steady decline over time in the US.
Experts said that lower smoking rates are due to anti-smoking campaigns, cigarette taxes, smoking bans and the launch and rise in popularity of e-cigarettes, New York Times reported.
