The deleterious health effects of tobacco smoking are global.



Currently, an estimated 6.0 million deaths per year worldwide are attributed to tobacco use (about 12% of all deaths). If current smoking patterns continue, it is projected that by 2030 eight million deaths per year will occur because of tobacco use, Tobacco will be the leading cause of disease burden worldwide by the 2020s, resulting in about 1 in every 8 deaths, a proportion greater than from any other single cause.  It is also estimated that, if current smoking patterns continue, 250 million children alive in the world today will eventually die from tobacco use. Worldwide, in 2000, smoking caused 71% of all lung cancer deaths, 11% of all cardiovascular deaths, and 22% of all cancer deaths. In industrialized countries, smoking caused 19% of total adult mortality (28% of total mortality among men and 9% among women). Overall, in industrialized countries, 92% of lung cancer deaths among men and 71% of lung cancer deaths among women were attributable to smoking. In developing countries, 55% of lung cancer deaths among men and 25% of lung cancer deaths among women were attributable to smoking. In developing countries, smoking caused 9% of total adult mortality (14% of total mortality among men and 3% of total mortality among women).
