According to the Centers for Disease Control and Prevention (CDC), in 2021, nearly 12 out of every 100 U.S. adults aged 18 years or older (11.5%) currently smoked cigarettes, which means an estimated 28.3 million adults in the United States currently smoke cigarettes. This is a significant drop from the mid-1960s when 42% of U.S. adults were smokers. The percentage of adult smokers dropped to about 11% in 2021, down from about 12.5% in 2020 and 2021. The CDC also reports that current cigarette smoking was highest among people aged 25–44 years and 45–64 years, and lowest among people aged 18-24 years. By race/ethnicity, current cigarette smoking was highest among non-Hispanic adults from other racial groups and lowest among non-Hispanic Asian adults.
