The tobacco epidemic is one of the biggest public health threats the world has ever faced, killing more than 8 million people a year around the world. More than 7 million of those deaths are the result of direct tobacco use while around 1.2 million are the result of non-smokers being exposed to second-hand smoke.Around 80% of the 1.1 billion smokers worldwide live in low- and middle-income countries, where the burden of tobacco-related illness and death is heaviest. Tobacco use contribtes to poverty by diverting household spending from basic needs such as food and shelter to tobacco. This spending behaviour is difficult to curb because tobacco is so addictive.The economic costs of tobacco use are substantial and include significant health care costs for treating the disease caused by tobacco use as well as the lost human capital that results from tobacco-attributable morbidity and mortality.In some countries, children from poor households are employed in tobacco farming to boost family income. These children are especially vulnerable to green tobacco sickness , which is caused by the nicotine that is absorbed through the skin from the handling of wet tobacco leaves.
