Apr 6, 2017- Smoking causes one in 10 deaths worldwide, a new study shows, half of them in just four countries - China, India, the US and Russia.
Despite decades of tobacco control policies, population growth has seen an increased number of smokers, it warned.
Researchers said mortality could rise further as tobacco companies aggressively targeted new markets, especially in the developing world.
The report was published in the medical journal The Lancet.
"Despite more than half a century of unequivocal evidence of the harmful effects of tobacco on health, today, one in every four men in the world is a daily smoker," said senior author Dr Emmanuela Gakidou.
"Smoking remains the second largest risk factor for early death and disability, and so to further reduce its impact we must intensify tobacco control to further reduce smoking prevalence and attributable burden."
