Smoking is the root cause of one in 10 deaths worldwide – and half occur within just four countries, according to a new study.
Tobacco-related deaths accounted for 11.5 percent of all deaths in 2015, despite on-going campaign efforts to convey the negative effects of smoking on public health.
The U.S., China, India and Russia emerged as the worst offenders in the new report published by medical journal The Lancet and sponsored by the Bill & Melinda Gates Foundation. These four nations accounted for 52.2 percent of all smoking-related deaths.
“Despite more than 50 years of anti-tobacco efforts, smoking remains a leading global risk factor,” the report noted.
