Is smoking really harmful? Why do many smokers live longer?
It is undeniable that everyone's physique is different, and their tolerance to harmful pollutants, nicotine and nicotine is different, which leads to some small probability events, that is, some people have smoked all their lives, and their lungs are fine. Some people have lung cancer instead of smoking all their lives.
Not only lung diseases, but also more infectious diseases have a lot to do with smoking! According to statistics, about 40% of the infectious diseases that smokers suffer in their lifetime are related to smoking. China consumes more than 9.2 billion cigarettes annually, and the number of smokers in China is as high as 320 million. With such a large population and high cigarette consumption, a small number of smokers live longer, which doesn't explain any problem.
As we all know, smoking is harmful! In addition to a slight dependence on cigarettes, some people like the smoky feeling when cigarettes burn. I don't know, these smog contain hundreds of chemicals harmful to human body, especially more than 40 carcinogens such as tar, nitrosamine and nicotine. Smoking for a long time is equivalent to chronic suicide.
If you smoke more than five cigarettes a day, 1 of four people will die of lung cancer! Maybe you will be surprised and think that this is not 100%. Don't forget, for an individual, it must be 100% probability! When misfortune happens to others, it may be a story, but it happens to yourself, right? A big accident?
How many smokers can there be 100? Unfortunately? Suffering from lung cancer has always been a concern. Who do you want to be? Lucky? ! The famous British Journal of Cancer once published a classic paper to answer this question: if you don't smoke, the probability of getting lung cancer before the age of 75 is only 0.3%; If you smoke regularly, the probability will reach16% (more than 50 times); If you smoke more than 5 cigarettes a day, the probability will be higher, reaching 25%! That is to say, 5 cigarettes a day, 1 person in 4 people will get lung cancer!
Try smoking with a filter! Cigarettes used to have no filters, but now some rural people are still used to smoking sweat cigarettes, not because they have no money, but because they think? Strong? ! Filter smokers have no energy!
Try not to smoke if you can! Smoking cessation addiction will not happen overnight. So do as little harm as possible to the body! Filter-tip cigarettes can partially reduce tar and nicotine when smoking, mainly blocking suspended particles produced during combustion.
Look at the picture below. The harmful substances originally inhaled into the lungs are partially blocked by the filter screen!
