Recently, CCTV ** A set of shocking **, revealing the devastating effects of smoking on the lungs. These** show the terrible changes in the lungs after 15 or 30 years of smoking, which is shocking. These once-healthy lungs are now covered with black spots, as if they have been smoked into black charcoal.
In China, lung transplant expert Chen Jingyu also showed a 30-year-old smoking. This lung has almost completely blackened, and it is accompanied by emphysema, tuberculosis calcification and other problems. It was supposed to be transplanted to save lives, but it was abandoned because the condition of the lung was so poor due to smoking.
The lungs of a normal person are pink and elastic, like a sponge. As people age, they inhale a lot of dust and their lungs gradually darken. However, smokers' lungs get worse. Smoking makes the lungs become like black charcoal, completely deprived of vitality and elasticity.
1.Respiratory problems: Smoking can lead to respiratory diseases such as chronic obstructive pulmonary disease (COPD), lung cancer, etc. The harmful substances in cigarettes can irritate the respiratory tract, leading to inflammation and infection, increasing the risk of developing these diseases.
2.Cardiovascular disease: Smoking can damage cardiovascular health and increase the risk of heart disease, stroke, and other diseases. The nicotine and other harmful substances in cigarettes can cause blood vessels to constrict, increasing blood pressure and heart rate, which can trigger cardiovascular problems.
3.Digestive problems: Smoking can affect the normal function of the digestive system, leading to digestive diseases such as stomach ulcers and gastritis. The harmful substances in cigarettes can damage the protective layer of the gastric mucosa and increase the secretion of gastric acid, which can cause digestive problems.
4.Immune system problems: Smoking weakens the function of the immune system, making people more susceptible to viruses and bacteria. The harmful substances in cigarettes can disrupt the normal function of immune cells and reduce the body's resistance to disease.
5.Neurological problems: Smoking can cause damage to the nervous system, leading to problems such as memory loss, difficulty concentrating, anxiety, and depression. The nicotine and other harmful substances in cigarettes can damage nerve cells and affect the normal function of the brain.
6.Increased health risk: Long-term smoking also increases the risk of other diseases, such as diabetes, liver disease, etc. Smoking affects multiple systems in the body, leading to various health problems.
In the experiment, the common thin-rod cigarettes on the market were selected for comparison with traditional cigarettes. First, we tested the smoke composition of two cigarettes. It was found that the content of harmful substances in the smoke of the cigarette was comparable to, and in some cases even higher, than that of conventional cigarettes. This suggests that thin-rod cigarettes do not reduce the harmful components in tobacco smoke.
Second, we conducted biological experiments to compare the toxicity of two cigarettes to human cells. The results of the experiment showed that the harm to the human body was similar to that of traditional cigarettes, and both would cause damage to human cells. This shows that the smoke does not reduce the harm to the human body.
In addition, we also investigated the inhalation of slender-stick cigarettes. The survey found that smokers often need to inhale more smoke to achieve the effect of traditional cigarettes due to the lower inhalation resistance of thin cigarettes. This means that smokers are likely to inhale more harmful substances when they smoke a thin cigarette.
First, let's be clear: smoking is bad for your health. Regardless of the method taken, smoking can be potentially harmful to your health. Therefore, the so-called "smoking to reduce harm" is actually a lie.
Some people may think that choosing low-tar, low-nicotine cigarettes, or using tools such as filters and e-cigarettes, can reduce the harm caused by smoking. However, the reality is that these methods do not really reduce the harmfulness of smoking.
Low-tar, low-nicotine cigarettes do not completely eliminate the health hazards of smoking. Tar and nicotine are the main carcinogens in cigarettes, and although low-tar, low-nicotine cigarettes reduce the intake of these components, there are still certain risks. In addition, smoking not only causes harm to the respiratory system, but also negatively affects several systems such as the cardiovascular system, digestive system, etc. Therefore, even if you choose a low-tar, low-nicotine cigarette, there is no guarantee that there will be no harm to your health.
Tools such as filters and e-cigarettes also don't completely eliminate the dangers of smoking. While these tools can reduce the amount of tar and nicotine ingested while smoking, they do not eliminate the harm of smoking to the body. In addition, there may be other health risks associated with the use of these tools, such as the fact that the liquids in e-cigarettes may contain chemicals that are harmful to humans.
To sum up, the ways in which smoking reduces harm are all deceptive. We should adopt scientific and effective methods to quit smoking, such as seeking professional help, using smoking cessation medications, etc. Only by completely quitting smoking can we truly reduce the harm of smoking to our health.
