Despite a steep drop in the number of smokers in many parts of the world, researchers say that cigarettes remain a growth industry because of an expanding population.
Global figures reveal that there are still more smokers today than ever.
In 2012, 967 million people smoked daily compared with 721 million in 1980, data from 187 nations indicates.
With the Earth’s population having more than doubled in the last 50 years, there are more people to take up the pack-a-day habit.
Global smoking rate
Even though the global smoking rate has declined, a number of large countries have seen increasing numbers of people take up smoking in recent years.
According to the report published in the Journal of the American Medical Association, some of the highest smoking rates are now seen in the developing world.
Around three in 10 men and one in 20 women now smoke every day compared with four in 10 men and one in 10 men in 1980.
