The study collected smokeless tobacco consumption figures for 115 countries and estimated burden of disease for 113 of these countries.It found that in 2010, smokeless tobacco use led to 62,283 deaths due to cancers of mouth, pharynx and oesophagus and 204,309 deaths from heart diseases. Kamran Siddiqi, senior lecturer in epidemiology and public health at the Department of Health Sciences/Hull York Medical School, said, “It is possible that these figures are underestimated and future studies may reveal that the impact is even bigger. We need a global effort to try and address and control smokeless tobacco.”
