One of the biggest health threats the world has faced
Tobacco will kill nearly six million people this year because governments are not doing enough to persuade people to quit.
This figure include 600,000 non-smokers according to the World Health Organisation (WHO).
With many years between when people first start to smoke, and when it actually begins to affect their health - the huge increase of tobacco related diseases and deaths has just begun.
The WHO also said that this death toll could rise to 8 million by the year 2030.
The United Nations health body has urged more governments to sign up to and implement its tobacco control treaty.
The European Union and 172 other countries have signed up to the WHO's Framework Convention on Tobacco Control (FCTC), which came into force in 2005 and ensures that they promise to take steps to cut the number of smokers, limit the exposure to second hand smoke and help to curb tobacco advertising and promotion.
Tobacco is described by the WHO as one of the biggest health threats the world has ever faced.
