If I smoke 10 cigarettes a day, what will it be like in ten years?

According to a new study, smoking can shorten people's life span 1 1 minute. If you smoke a pack of 20 cigarettes a day, it may reduce people's life expectancy by about 3 hours and 40 minutes. This estimate is based on people who started smoking at the age of 17 and died at an average age of 7 1 7. Suppose he smokes 15 cigarettes a day like the average British addict, he will consume 3 1 1688 cigarettes in his life. On average, smokers die six and a half years earlier than non-smokers.

A similar study decades ago concluded that every cigarette smoked would shorten life expectancy by five minutes. But since then, non-smokers have obviously enjoyed a longer life span, so the harm of cigarettes to life span has increased relatively.

At present, about one-third of people in Britain smoke, and about120,000 people die of smoking-related diseases every year, two-thirds of which are cancer and heart disease. Researchers hope that this new study will encourage more people to make up their minds to quit smoking at the dawn of the new century.

The host of a smoking cessation action group said that this figure shows that if a person smokes 20 cigarettes a day, it means that he will lose one day every week he smokes; If this is not bad enough, he warned, smoking may cause people to die painfully or stay in bed more frequently.

Tobacco smoke contains at least three dangerous chemicals: tar, nicotine and carbon monoxide. Tar is a mixture of several substances, which will be concentrated into a viscous substance in the lungs. Nicotine is an addictive drug, which is absorbed by the lungs and mainly acts on the nervous system. Carbon monoxide reduce that ability of red blood cells to deliver oxygen to the whole body.

A person who smokes/kloc-0.5 to 20 cigarettes a day is four times more likely to develop lung cancer, oral cancer or laryngeal cancer and die than a non-smoker. The mortality rate of esophageal cancer is four times higher than that of non-smokers. The risk of dying from bladder cancer is twice as high; The risk of dying of heart disease is twice as high. Smoking is the main cause of chronic bronchitis and emphysema, and chronic lung disease itself will increase the risk of pneumonia and heart disease, and smoking will also increase the risk of hypertension.

Smoking is harmful to your health.

According to Jeffrey Smith, an American dermatologist, a survey of 58,726 smokers in this country found that smoking not only damages the heart and lungs and consumes vitamin C in the body, but also harms the skin.

1, wrinkles

Like exposure to sunlight, smoking can cause elastin and elastic fibers to thicken or break. In addition, smoking will also reduce the oxygen supply to the skin, affect the formation of collagen, the main component of the skin, and lead to dry skin. All these aggravate the appearance of wrinkles. For female smokers, it will also affect the estrogen cycle.

2. Skin cancer

Smoking can induce carcinosarcoma. After the appearance of melanoma, smokers are twice as likely to have melanoma necrosis as non-smokers.

3. Other cancers

Smokers have a much higher risk of developing cancer of lip, mouth, penis, anal cancer and vulva than non-smokers.

4. The wound heals slowly

After abdominal surgery or facial plastic surgery, the wound healing of female smokers is obviously slower than that of non-smokers. The failure rate of skin transplantation in smokers is also high.

5, psoriasis and skin diseases

Smokers are 2-3 times more likely to suffer from psoriasis than non-smokers. Some abscesses on the palms and feet are almost unique to smokers. This skin disease is difficult to cure, even if you quit smoking in the future, it will not disappear.

6, oral lesions

Tar in cigarettes and the heat of cigarettes will inflame salivary glands, thus forming abscesses or mucosal leukoplakia on the tongue and palate. Smokers are six times more likely to suffer from mucosal leukoplakia than nonsmokers. Although leukoplakia is benign, it may also induce cancer. Nicotine in tobacco is a highly toxic alkaloid.

A cigarette shortens life 1 1 min.

According to a new study, smoking can shorten people's life span 1 1 minute. If you smoke a pack of 20 cigarettes a day, it may reduce people's life expectancy by about 3 hours and 40 minutes. This estimate is based on people who started smoking at the age of 17 and died at an average age of 7 1 7.

Smoking after meals is harmful.

"A cigarette after a meal is better than a living fairy" is a famous saying of smokers. However, according to the research results, gastrointestinal peristalsis increases after meals, blood circulation is accelerated, and smoking ability is the strongest. At this time, when smoking a cigarette, the harmful substances in the cigarette are easier to enter the blood than usual, and the toxic amount is greater than the sum of 10 cigarettes smoked at ordinary times.

Three Harms of Smoking

Tobacco contains more than 20 kinds of toxins after burning, and nicotine is the most harmful to life. In this respect alone, smoking has three major hazards:

1, which can kill directly.

The surprising results are as follows: (1) No matter how big the horse is, it can't stand injecting 8 doses of nicotine and will soon die; A lively dog can be killed without injecting a drop of nicotine into the vein; In addition, after smoking for a long time, some animals can find that there is an obvious trend of vasoconstriction and even hardening.

2, it can destroy the nutrients of the human body.

Nicotine has a direct destructive effect on vitamin C. If the human body lacks vitamin C for a long time, there is the possibility of scurvy.

3. Lure various diseases

It has a malignant stimulating effect on respiratory tract, digestive tract and other organs, so some people think that it is an inducing factor for gastric and duodenal ulcers, respiratory tract infections and even cancers such as mouth, lips, tongue, esophagus and respiratory tract.

From this point of view, smoking is harmful to human health. So try to quit smoking or smoke less. Non-smokers had better not get into this hobby.

Teenagers' Bad Behavior-Smoking

Smoking is very common among teenagers in China. Although the Law on the Protection of Minors in People's Republic of China (PRC) and the Code for Middle School Students stipulate that minors and middle school students are not allowed to smoke, the number of teenagers who smoke is still quite large, and there is an upward trend. It is estimated that the smoking rates of male students in senior high schools and junior high schools in China are 68% and 54% respectively.

Teenagers smoking is an extremely harmful bad behavior.

First of all, it is harmful to life. Teenagers smoking is more harmful than adults. Because teenagers are in the stage of rapid growth and development of their bodies, their organs and systems are not yet mature, immature and sensitive, and their resistance is not strong, so they absorb all kinds of toxic substances more easily than adults, so they are deeply poisoned. Adolescent smoking may also lead to premature aging and premature death, which will affect the development of the next generation. Smoking can lead to menstrual disorder and dysmenorrhea in girls.

Second, smoking is harmful to psychological function. Long-term smoking will lead to a certain degree of attention and stability decline, but also reduce people's intelligence level, learning efficiency and work efficiency. Teenagers' smoking addiction may lead to serious degradation of thinking process and damage of intellectual function, and may seriously lead to thinking interruption and memory disorder. Smoking is harmful to teenagers' intelligence, personality, psychological quality and study.

Third, teenagers' smoking will encourage their hedonistic attitude towards life, increase their parents' financial burden, encourage bad communication, induce bad behavior and even lead to crime. In order to get the money for cigarettes, I will steal, blackmail and rob.

Teenagers smoking will also bring serious harm to society. Smoking has now become an important cause of fire accidents and endangering public safety. Cigarette smoke will pollute the surrounding environment and harm the health of others.

Cigarettes contain 43 carcinogens, and smoking can cause cancer 14.

According to a survey conducted by the British Heart Foundation by Xinhua News Agency, 19% people have realized that the biggest threat to smokers is heart disease and blood circulation diseases. The researchers also warned that smoking is associated with at least 14 different cancers.

The close relationship between lung cancer and smoking has been widely known. Scientists of the Cancer Research Association have proved that women infected with sexually transmitted papillomavirus are more likely to suffer from uterine cancer if they smoke.

Studies have also shown that smoking is related to at least eight other serious diseases, including heart disease, stroke, emphysema and cataract; Not only that, smoking will also affect fertility and reduce the birth weight of babies.

Philip, a scientist at the Cancer Research Association, said: "Our findings are comprehensive and simple. Smoking can cause all kinds of cancers. We need to continue to tell smokers how harmful cigarettes are to their health. "

The researchers analyzed 3,500 different chemicals in cigarettes, of which at least 43 are carcinogens. The British Heart Foundation also warned that one fifth of patients with coronary heart disease in Britain are caused by smoking, and 4,000 people die of heart disease and blood circulation diseases every year.

At present, more than 600 million people in China are poisoned by secondhand smoke.

Medical experts say that the number of passive smokers in China is as high as 600 million. It is urgent to establish a smoke-free social environment and raise the awareness of non-smokers to protect their rights and interests.

He Yao, executive director of China Smoking and Health Association and associate professor of the Institute of Geriatrics of PLA General Hospital, recently pointed out at the 8th National Symposium on Smoking and Health that passive smoking is quite common in China, especially harmful to women and children.

According to the definition of the World Health Organization, passive smoking means that non-smokers inhale the smoke exhaled by smokers for more than 15 minutes every day for more than one day in a week.

He Yao said that the passive smoking rate in China is 52.5%, of which the passive smoking rate of women is 57%, which is as high as 70% among professional women aged 20 to 49. According to this calculation, as many as 600 million people are harmed by passive smoking in China. In China, 7 1% families, 32.5% public places and 25% workplaces become passive smoking places because people smoke.

He Yao said that the scientific basis of passive smoking's harm to health has been confirmed, and its carcinogenic mechanism is: the generation of reactive oxygen species (free radicals) damages genes and cell membrane proteins, and promotes the occurrence of diseases and tumors. Passive smoking can also reduce the oxygen carrying capacity of hemoglobin and the oxygen utilization capacity of myocardium.
