Around 6.4 million deaths worldwide in 2015 was attributed to smoking and nearly half of those were from China, India, the United States and Russia, according to medical journal Lancet.
Although the journal lauded India for adopting a large number of tobacco control policies over the last ten years, a little over 11 per cent of the world's smokers are from India.
While the percentage of Indian men smoking has reduced slightly since 1990, data for Indian women remains largely unchanged during the same time span.
Globally, one in four men and one in 20 women smoked daily in 2015, according to the Global Burden of Diseases report, compiled by hundreds of scientists.
That was a significant drop compared to 25 years earlier, when one in three men, and one in 12 women, lit up every day.
But the number of deaths attributed to tobacco -- which topped 6.4 million in 2015 -- went up by 4.7 percent over the same period due to the expanding world population, the report found.
More than 930 million people smoked daily in 2015, compared to 870 million in 1990 -- a seven percent jump.
Mortality could rise even further as major tobacco companies aggressively target new markets, especially in the developing world, they warned in a report, published in the medical journal The Lancet.
"Smoking remains the second largest risk factor for early death and disability" after high blood pressure, said senior author Emmanuela Gakidou from the Institute for Health Metrics and Evaluation at the University of Washington, in the US northwest.
