Statistics show that at present, 6.5438+0.4 million people worldwide die of cancer caused by cigarettes every year, and on average, 654.38+0 out of every 5 cancer deaths are caused by cigarettes. Coupled with cardiovascular diseases and lung diseases caused by smoking, 5 million people worldwide die from cigarettes every year. Experts estimate that this number is still rising.
On June 5438+00, officials of the World Health Organization and the American Cancer Society warned that according to the current development trend, cigarettes will probably kill 654.38 billion people in 2 1 century, and the death toll will be 10 times that of the 20th century.
The World Health Organization said in its report that cigarette consumption is the cause of 4.9 million deaths every year. If no control measures are taken, this number will rise to 8.4 million by 2020. 70% of them are in developing countries. According to the report, cigarette consumption in Africa, Asia, Eastern Europe and the Middle East will continue to increase, while that in Western Europe will decrease and that in the United States will remain stable. But on the whole, cigarettes are still a big problem threatening public health, because the number of young smokers in developing countries has been increasing.
In some countries, 60% of teenagers aged 13- 15 smoke regularly. In Russia, Bolivia, Chile and other countries, boys are more likely to smoke, while girls in Ukraine and Argentina smoke more. Children are the most vulnerable, because a person's habits often start from a very young age, so they become the target of tobacco companies. The world consumes 654.38+0.5 billion packs of cigarettes every year, and the countries with the largest proportion of cigarettes in national consumption are Spain, Switzerland, Belarus, Hungary, Bulgaria, Yugoslavia and Greece. As far as gender is concerned, most smokers are male citizens. There are 6,543.8 billion male smokers in the world, including 300 million in China.
Judith McKay, senior policy adviser of the World Health Organization, said: "If we start smoking bans now, we can save 2 million lives by 2020; By 2040, we can save 6.5 million lives. " 2. The mortality rate of smoking. Every 10 second, one person in the world dies at the hands of "cigarettes". This is not sensational, this is the figure released by the World Health Organization. The incidence of lung cancer is 10.8 times that of non-smokers. The annual mortality rate of lung cancer in non-smokers is 12.8/65438+ 10,000; 95.2/65,438+ten thousand people smoke less than 65,438+00 cigarettes a day; The number of people who smoke more than 20 cigarettes a day is 235.4/65438+ million, which is 18.4 times that of non-smokers. 3.
