According to the Lancet medical Journal forty percent of men in developing countries either smoke or use smokeless tobacco. Tobacco is likely to kill half of its users. There are huge disparities in the rates of smoking between countries and genders. By 2030 if current trends continue it predicts tobacco could be killing 8 million people a year. Although 1.1 billion people have been covered by the adoption of the most effective tobacco-control policies since 2008 83 percent of the world's population are not covered by two or more of these policies said Gary Giovino of the University at Buffalo
