Tobacco use is a major cause of preventable disease, death, and disability worldwide. About 7 million people die from tobacco use each year worldwide, including more than 890,000 from exposure to secondhand smoke. Because tobacco use is declining in most developed countries, most tobacco-related deaths are projected to be in the developing world. This is due, in part, to tobacco industry efforts to promote their products in African markets. Without comprehensive tobacco prevention and control efforts, the prevalence of tobacco smoking in sub-Saharan Africa is estimated to rise from 15.8% in 2010 to 21.9% in 2030.
