It is reported that the mortality rate of smokers is 2.5 times higher than that of non-smokers.
The burden of smoking on society is far greater than its contribution to tax revenue.
In the United States, the total tobacco sales of 1984 is $28.7 billion. However, the loss of workers' illness, absenteeism and premature death caused by smoking reached $53.7 billion. This figure is 0.8 times that of 65438+ US government tobacco tax.
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.
There are about 1 1 billion smokers in the world, accounting for about 1/3 of the global population over 5 years old. Although tobacco consumption in developed countries has declined since1early 1980s, this decline has been offset by the corresponding growth in underdeveloped countries. If the current trend continues, the annual death caused by tobacco is estimated to be 1000.
It is estimated that tobacco causes 3 million deaths every year, and the number of deaths is still rising steadily. If it is not reversed, it is estimated that by 2000 or 2023 (now young smokers enter the middle-aged and elderly stage), the number of smoking deaths will reach100000. Among all smoking-related diseases, the most important ones are lung cancer and cardiovascular diseases.
1950 ~ 2000, 62 million people will die from smoking in developed countries, accounting for 12.5% of the total population, and more than half of them (equivalent to 38 million) will die at the age of 36 ~ 69. At present, smoking is the main cause of death of middle-aged men, accounting for more than 1/3 of the total number of deaths (up to 36%). For middle-aged women, smoking deaths account for 1/8 of their deaths. The life expectancy caused by smoking in the above age groups is 22 years lower than the average life expectancy.
Cigarettes contain more than 1400 components. There are more than 40 carcinogens in the smoke produced by smoking, and there are more than 10 substances that can promote the development of cancer, among which nicotine, carbon monoxide and other metal compounds are the most harmful to human body. A cigarette contains enough nicotine to kill a mouse. The binding capacity of carbon monoxide and hemoglobin in cigarette smoke is 240-300 times greater than that of oxygen, which seriously weakens the oxygen carrying capacity of red blood cells. Therefore, smoking accelerates blood coagulation and easily causes cardiovascular diseases such as myocardial infarction, stroke and myocardial hypoxia. What's more, smokers also seriously hinder the health of others. The results show that a smoker does more harm to others than to himself when smoking.
