Miami: The number of cigarette smokers in the United States has dropped to about 15 per cent of the population, its lowest point in decades, US health authorities said Tuesday.

‘The prevalence of current cigarette smoking among US adults declined from 24.7 per cent in 1997 to 15.2 per cent in January–March 2015,’ said the report by the Centers for Disease Control and Prevention’s National Center for Health Statistics.

The figures will be updated once the entire year’s data is available.

Smoking continues to be more common among men (17.4 per cent) than women (13.0 per cent), the report found.

Smoking is most common among African Americans (18.1 per cent), followed by whites (17.1 per cent) and Hispanics (10.4 per cent).

According to the US surgeon general, smoking is known to cause ‘a host of cancers and other illnesses and is still the leading preventable cause of death in the United States, killing 480,000 people each year.’

Smokers made up 42 per cent of the US population in 1965, a fraction that has dropped steadily over the years, according to the CDC.
