★Smoking by pregnant women is harmful to both themselves and their children
According to the latest research, women smoking during pregnancy is not only detrimental to their own health, but will also directly affect their children’s future health. Behavior has a negative impact.
Dr. Judith Brooke of Mount Sinai School of Medicine in New York, who led the study, said the findings confirmed some previous views that women who smoke during pregnancy are more likely to have children who are pregnant. The queen is prone to irritability and even has the tendency to commit crimes.
Researchers investigated some children around 2 years old and found that whether they had negative behaviors was directly related to how much their mothers smoked during pregnancy. The more mothers smoked during pregnancy, the more their children were impulsive, had tantrums, and were often unwilling to listen to others.
The researchers finally advise mothers not to smoke during pregnancy, for the sake of their children and themselves.
★One cigarette can shorten a person’s life by 11 minutes
According to a new study, smoking one cigarette can shorten a person’s life by 11 minutes. If you smoke a pack of 20 cigarettes a day Cigarettes may shorten a person's life by approximately three hours and forty minutes.
This estimate is based on a man who started smoking at the age of seventeen and died at an average age of seventy-one. It is assumed that he smoked fifteen cigarettes a day like the average British drug addict. A lifetime will consume 311,688 cigarettes. Smokers will die on average six and a half years earlier than non-smokers.
A similar study conducted decades ago concluded that each cigarette smoked reduces a person's life by five minutes. However, since then, since non-smokers obviously live longer, the harm of cigarettes to lifespan has relatively increased.
About one-third of the UK population currently smokes, and approximately 120,000 people die each year from smoking-related diseases, two-thirds of which are cancer and heart disease. Researchers hope this new study will encourage more people to decide to quit smoking in the new century.
The host of a smoking cessation action group said that this figure shows that if a person smokes twenty cigarettes a day, it means that he will lose one day of life for every week he smokes; if that is not bad enough If so, he cautioned, smoking could also make death more painful or bedridden more often.
★Smoking affects ulcer healing
Many patients with ulcers who have a smoking habit still have ulcers that do not heal despite long-term medication. The reasons may be many, but smoking is one of the important factors.
Smoking has three main effects on ulcers:
1. Increased incidence. Japanese scholars have found that the incidence of ulcer disease in smokers is 2 to 4 times that of non-smokers.
2. Reduce the cure rate. Someone has done a comparison and gave the same medicine to two groups of ulcer patients. The cure rate of the non-smoking group was 90%, while the smoking group was only 63%.
3. It is easy to cause recurrence. Comparing the above groups of patients one year after stopping the drug, the recurrence rate was 84% ??in the smoking group and 53% in the non-smoking group.
★"Second-hand smoke" is more harmful than tigers
American medical researchers recently published a research report pointing out that passive smoking, commonly known as "second-hand smoke", is more harmful than previously known. It is dangerous. Some women who live with smokers are 6 times more likely to develop lung cancer than ordinary people.
As for the prevention of lung cancer, staying away from cigarettes and smoke is the wisest move. At the same time, not only try not to smoke, but also don't let yourself be exposed to "second-hand smoke". Even in public places, you should try to avoid those who smoke to avoid being harmed by "second-hand smoke".
★Smoking causes many cardiovascular and cerebrovascular "disasters"
Cerebrovascular diseases are also among the many harms caused by smoking to the human body. According to long-term surveys, smokers aged 30 to 40 years old have a 5 times higher incidence of cerebrovascular disease than non-smokers, and those aged 50 to 60 years old have a 3 times higher incidence rate. Moreover, the number of deaths due to cerebrovascular diseases is 2 to 6 times higher than that of non-smokers, and is closely related to the amount of smoking.
Cigarettes contain more than 400 chemical substances, many of which are closely related to cerebrovascular diseases. These include carbon monoxide. The carboxyhemoglobin in the blood of people who smoke for a long time can be as high as 10% to 15%, thus reducing the ability of red blood cells to transport oxygen, forcing the bone marrow to overproduce red blood cells to make up for the deficiency. Increased red blood cells increase blood viscosity. In addition, smoking can also increase adrenal secretion, and its secretions can promote platelet aggregation, which is also the reason for increased blood viscosity. Increased blood viscosity slows blood flow, and red blood cells and platelets tend to aggregate into clumps, blocking blood flow and causing ischemic cerebrovascular disease.
It is well known that nicotine is contained in cigarettes, and it is also a stubborn culprit in promoting ischemic cerebrovascular disease. Nicotine can cause nerve endings and adrenal glands to release epinephrine and norepinephrine. These two substances can constrict blood vessels, thus increasing blood flow resistance, slowing blood flow and making it easier to accumulate. During vasoconstriction, the gap between vascular endothelial cells expands, allowing low-density lipoprotein to enter the sublayer of the arterial endothelium through the expanded gap to form atherosclerotic plaques. Atherosclerosis is one of the risk factors for cerebrovascular disease.
Each cigarette contains 0.1 microgram to 0.2 microgram of metallic cadmium, which can increase blood pressure.
In addition, carboxyhemoglobin causes myocardial hypoxia, causing myocardial damage and impairing cardiac function. These are also risk factors for cerebrovascular disease.
It is not alarmist to say that smoking has hundreds of harms but no benefits. 60% of adult males in my country have a history of smoking, and the trend is gradually increasing and is developing towards teenagers. Quitting smoking is not difficult. According to a survey of nearly 160,000 people by the American Cancer Research Association, about half of smokers successfully quit smoking at one time, and 95% of them did not take any smoking cessation drugs.
★Men who smoke are six times more likely to be infertile
A medical research team from the National University of Singapore came to a conclusion after analyzing semen samples from men with normal fertility and infertile men. ——Smoking reduces sperm count and makes individual sperm weaker.
In the past, when the team studied male infertility, they only analyzed sperm samples from infertile men and did not analyze them together with sperm from normal men.
After comparing sperm samples from 240 men with normal reproductive potential and 218 infertile men, researchers found that smoking men with lower than average sperm counts were more likely to have sperm than non-fertile men. Men who smoke are six times more likely to be infertile.
The team also found that smoking men with normal sperm counts were 16 percent more likely to be infertile than non-smoking men with similar sperm counts. In other words, if smokers want to have children, normal sperm count alone is not enough.
Noel, a member of the research team, said that fifty years ago, men had an average of 130 million sperm per milligram of semen, but today, there are only 65 million sperm per milligram.
Experts say that low sperm count is only one of the important signs of male infertility. Other factors include whether the sperm's motility and shape are normal.
★Men’s smoking harms their quality of life
Some bad habits can also cause male infertility, and smoking is one of them. Scientific research and clinical data show that most people who smoke for a long time and smoke more than 20 cigarettes a day have a sperm motility rate (power) of less than 50%, and their motility is also significantly reduced. For those who smoke and drink alcohol, the decline in sperm quality is more obvious.
According to Canadian researchers, not only do men who smoke have lower sperm quality than non-smoking men, but their sexual desire is significantly reduced. In a questionnaire survey involving 290 couples, they asked the surveyed couples to answer their smoking habits, marital history and sexual life conditions, including the number and satisfaction of sexual life. None of the women in the survey were smokers. However, in 158 of the couples, the man smoked at least 30 cigarettes a day for more than seven years.
The results showed that smokers had sex an average of 7 times per month; non-smokers had sex 11.6 times a month on average. And non-smoking couples were significantly more satisfied with their sex life than smoking couples. If the maximum score for a completely satisfactory sex life is set at 10 points, then non-smokers score 8.7 points and smokers score 5.2 points.
In addition, the results of semen analysis show that: compared with non-smokers, the number, motility and lifespan of sperm in smokers are reduced, and the degree of impact is proportional to the number of years of smoking. .
There are many harmful substances in tobacco, among which nicotine is particularly toxic, with the content in a cigarette being about 1 mg. Nicotine inhibits the secretion of sex hormones and kills sperm. Smoke extracts or urine extracts from heavy smokers contain substances that induce cell aberrations and inhibit DNA synthesis in lymphocytes, poisoning the seminiferous epithelium of the testicles and lowering the quality of semen. The harmful substances in tobacco can also cause erectile dysfunction by inhibiting the secretion of testosterone and damaging the walls of penile arteries, resulting in reduced sexual intercourse and even the inability to erect the penis. At the same time, tobacco toxins can hinder the combination of sperm and eggs, greatly reducing a woman's chance of pregnancy.
Smoking can also cause local high-concentration air pollution, causing wives and family members to inhale "second-hand smoke", which not only affects their own fertility, but surveys have shown that the incidence of serious congenital malformations in babies will also increase with time. increased as the father's smoking increased. In view of the many dangers mentioned above, please quit smoking as soon as possible! This is especially true for infertile patients.
★Women lose their health and beauty when they smoke
It is an indisputable fact that smoking is harmful to health. It certainly does not take special care of women, but only hurts them more deeply because women are more delicate than men.
Zhu Yuanjue, a member of the National Committee of the Chinese People's Political Consultative Conference and a professor of respiratory medicine at Union Hospital, told the author: In the 1960s and 1970s, the proportion of women suffering from lung cancer was very small, but now the number of women suffering from lung cancer has increased significantly. The main reason is that women who smoke The number of people surged. There are two major categories of respiratory harm. Chronic bronchitis and emphysema are two diseases in which 30% are caused by smoking.
According to experts, because women have reproductive systems and the characteristics of giving birth to offspring, they suffer more serious harm than men.
In other words, all the aspects of smoking that harm men are applicable to women. In addition, smoking also brings many additional harms to women:
Smoking will have an adverse impact on the respiratory tract of the next generation;< /p>
Smoking women have a 40% higher risk of ectopic pregnancy than non-smokers;
Smoking women are 2.7 times more likely to suffer from infertility and have a higher chance of cervical cancer than non-smoking women 50%;
Women who have smoked for more than 20 years have a 30% increased risk of breast cancer;
Smoking can also make women age prematurely: premature wrinkles appear on lips and corners of eyes, teeth Yellowing, rough skin, loss of elasticity and plump appearance, and even beard growth.
Smoking can also greatly increase the likelihood of dysmenorrhea, bone fragility, urinary incontinence, and reduced breast milk secretion.
In addition, according to a survey published in the "Chinese Medical Forum", pregnant women who smoke more than 10 cigarettes a day have a 44.8% incidence of premature babies, which is twice that of non-smokers. The U.S. Federal Centers for Disease Control has proven after 10 years of research that 66.7% of babies born to mothers who smoked during pregnancy were born with a low birth weight, less than 2,500 grams. Even if such a baby barely survives, he or she may become mentally retarded or have dementia. British scholars surveyed more than 60,000 female smokers and found that pregnant women's smoking is much more likely to cause birth defects in babies than the average person.
Whether you choose health and beauty, or choose smoky, smart people, it’s up to you.
★Smoking and Cancer
Smoking can cause about 85% of deaths from lung cancer; 80% of deaths from larynx, pharynx, oral cavity and lip cancer; 75% of deaths from esophageal cancer; 45% of deaths from esophageal cancer of bladder cancer deaths; 30% of cervical and pancreatic cancer deaths and 20% of stomach cancer deaths. The cancer mortality rate for smokers is 2 times higher than for non-smokers; for heavy smokers, it is more than 4 times higher.
Smoking not only causes cancer in direct contact parts (mouth, pharynx, larynx and lungs), but also causes cancer in distant parts. For example, almost 50% of male deaths from bladder cancer and kidney cancer are caused by smoking, and smokers are 2 to 3 times more likely to develop bladder and kidney cancer than non-smokers. 30% of the 4,600 cervical cancer deaths in the United States each year are caused by smoking. Passive smoking (including polluted air) has also been confirmed to be a cause of cancer in non-smokers, especially harmful to children!
★Smoking spouses will eat more fat
Researchers at Arizona State University in the United States pointed out at the 2000 Annual Meeting of Experimental Biology held in San Diego this week that smokers The spouse's daily dietary fat intake, as well as the amount of saturated fat, was far greater than that of the non-smoker's spouse.
The researchers analyzed various nutritional data from 500 married couples between 1994 and 1996 and found that non-smoking women married to male drug addicts were less likely to smoke than women married to non-smoking men. The total intake of fat from the diet is high, while the intake of fiber and vitamin A is low. Meanwhile, men who were non-smokers but were married to a female addict fared even worse in terms of their diet. The survey results show that not only do they consume more fat per day than men married to non-smoking women, but their daily intake of alcohol and cholesterol is also significantly higher than the latter, but the intake of vitamin A, fiber and calcium is lower than that of men married to non-smoking women. The input is less.
As for the reasons for the above results, the researchers pointed out that part of the reason is because women are usually responsible for the family's dietary arrangements. Therefore, if a woman herself smokes, the probability of her spouse showing signs of poor dietary structure is higher than that of a smoker. Male spouse.
The only solution is for the non-smoker of the couple to openly ask the other to quit smoking, and on this basis improve the family's dietary structure, including reducing the frequency and quantity of alcohol and intake of alcohol, the researchers said. Include more vegetables and fruits. Researchers believe that improvements in diet can help couples avoid cancer, heart disease and a host of other diseases.
★Smoking after a meal is very harmful
“A cigarette after a meal is better than a living god” is a famous saying of smokers. However, research results show that gastrointestinal motility increases after meals, blood circulation accelerates, and the ability to absorb smoke is the strongest. If you smoke a cigarette at this time, the harmful substances in the cigarette will enter the blood more easily than usual, and the poisoning amount will be greater than the sum of 10 cigarettes you usually smoke.
★Smoking damages male spermatogenesis
Xinhua News Agency, Harbin, a medical study recently found that smoking can cause serious damage to the spermatogenesis of male rats, and the ability of sperm to induce pregnancy is greatly reduced. This result provides important clues for further research on the corresponding harm of smoking to men.
Zhang Cheng, a master's student in the Department of Urology at the First Clinical School of Medicine at Harbin Medical University, has been committed to researching the impact of smoking on the male reproductive system. He put 20 male rats in a special poison-contaminated tank every day. Let them passively "enjoy" top-quality cigarettes (10 to 12 cigarettes each time) for 60 minutes. After 8 weeks, the testicles and epididymis of 10 rats were removed; the testicles of the other 10 rats were also removed 48 days after "quitting smoking". and epididymis.
He decomposed the testicles and epididymis into individual cells, and then used advanced flow cytometry technology to study the changes in the DNA content of rat sperm at the molecular level. After dissecting and comparing the two groups of smoking rats with normal rats, he found that: the first 10 The spermatogenic cells and sperm DNA maturity of the rats were much lower than those of normal rats, while the spermatogenic functions of the other 10 "quit smoking" rats had recovered somewhat compared with the first 10 rats.
Zhang Cheng believes that sperm development is a delicate and perfect regulatory process, and it is also a fragile process of change. Any link in it may be damaged by toxins and cause spermatogenesis disorders. Cigarette smoke contains more than 3,600 toxic chemicals and carcinogens and teratogens, which can easily interfere with the normal spermatogenesis process of the testicles, resulting in a decrease in semen quality and sperm's ability to induce pregnancy. He warned men of childbearing age to avoid smoking.
★Smoking makes you susceptible to pathogenic bacteria
A medical report said that smokers are 4 times more likely to be infected with meningitis, toxemia, pneumonia and ear diseases than others. many.
500,000 people in the United States become sick each year due to infection with this bacterium, and more than 40,000 people die every year. This bacterium is also the main cause of death in children.
Not only smokers are affected by these germs, but non-smokers who smoke passively for only one hour a day are also infected with these germs. They are two and a half times more likely to be infected than ordinary people.
Experts say the more you smoke, the more likely you are to contract these germs, especially those who drink alcohol and smoke. Children living in families with smokers are at greater risk of contracting these diseases.
★Smoking can seriously damage your health
Tobacco smoke contains at least three dangerous chemicals: tar, nicotine and carbon monoxide. Tar is a mixture of several substances. The substance will condense into a viscous substance in the lungs. Nicotine is an addictive drug that is absorbed by the lungs and primarily affects the nervous system. Carbon monoxide reduces the ability of red blood cells to carry oxygen throughout the body.
A person who smokes 15 to 20 cigarettes a day is 14 times more likely to die from lung cancer, oral cancer or laryngeal cancer than a non-smoker; he is more likely to die from esophageal cancer. They are four times more likely than non-smokers; twice as likely to die from bladder cancer; and twice as likely to die from heart disease. Smoking cigarettes is the main cause of chronic bronchitis and emphysema. Chronic lung diseases themselves also increase the risk of pneumonia and heart disease. Smoking also increases the risk of high blood pressure.
Oral cavity and throat
Cigarette smoke (especially the tar contained in it) is a carcinogen - that is, it can be present in the tissues it comes into contact with. Therefore, any part of the smoker's respiratory tract (including the mouth and throat) is likely to develop cancer.
★Heart and Arteries
Nicotine can speed up the heartbeat and increase blood pressure. Tobacco smoke seems to promote the accumulation of atherosclerosis, which may be due to the carbon monoxide contained in it. This situation is a cause of many heart diseases. People who smoke a lot are much more likely to die from a heart attack than non-smokers.
★Poisons in cigarette smoke
Cigarette, cigar and pipe smoke contain many different substances. There are three most harmful substances, which are tar, nicotine and carbon monoxide. These three things are responsible for the early death of many smokers.
Smoking women taking birth control pills will increase the risk of taking pregnancy pills. Pregnant women who smoke 15 to 20 cigarettes a day have twice the chance of miscarriage than non-smoking women, and are more likely to give birth. For premature babies or babies with weak constitution, the postpartum mortality rate of babies born to smoking women is about 30% higher than that of babies born to non-smoking women.
There is also so-called "pure smoking", or second-hand smoke, which will increase the chance of lung cancer for non-smokers. Some brands of cigarettes have lower tar and nicotine content than other cigarettes. However, There is no completely "safe" cigarette in the world. Therefore, it may not necessarily help if you switch to "light" cigarettes. Habitual heavy smokers often develop a habit of taking deep puffs and lighting more often when switching to lighter cigarettes.
Esophagus
Most smokers like to swallow a certain amount of cigarettes, so the digestive tract (especially the esophagus and pharynx) is at risk of cancer.
Lungs
The fine hairs that line the airways in the lungs usually remove foreign matter from the lung tissue. These villi will continuously sweep the particles in the lungs into phlegm or mucus and expel them. In addition to causing cancer, the chemicals in tobacco smoke will also gradually destroy some villi and increase mucus secretion, leading to chronic diseases in the lungs. Susceptible to bronchitis. Apparently, "smoker's cough" occurs because the mechanical efficiency of lung cleansing is compromised, resulting in increased phlegm production.
Bladder
Bladder cancer may be caused by inhaling cancer-causing chemicals contained in tar, which are absorbed into the blood and then passed out in the urine.
★Passive smoking is more harmful than tigers
American medical researchers recently published a research report pointing out that passive smoking, commonly known as "second-hand smoke", is more harmful than previously known. Dangerous, some women who live with smokers are 6 times more likely to develop lung cancer than ordinary people.
The study, which examined tissue from 106 women living with smokers in Missouri, found that women with mutations in a gene called "GSTMI" or a lack of it, The chance of developing lung cancer is 2.6 to 6 times that of the average person. The "GSTMI" gene is currently considered to inactivate the carcinogens in tobacco. "Secondhand smoke" is more harmful than imagined. The researchers said that this study is currently a small-scale experiment and needs to be further confirmed and expanded. However, if this study is correct, then the environmental smoking problem is far more dangerous than previously known.
Lung cancer is considered by the medical community to be a disease of civilization, because its seriousness continues to emerge with the progress of society. Since the beginning of the 20th century, the incidence of lung cancer has increased significantly, growing faster than other cancers. In the 1920s, there were only about 370 reports of lung cancer cases in the world, but by the 1950s, the number of people suffering from lung cancer in the United States alone was as high as 18,300.
The main culprit of lung cancer
In just 20 years from the early 1950s to the early 1970s, male lung cancer increased by 122%, and female lung cancer increased by 177%. Currently, it is estimated that there are 660,000 new cases of lung cancer in the world every year. Lung cancer is also one of the top ten most common cancers among Singaporeans, especially men. Lung cancer patients rank among the top two or three among all cancers. As for the causative factors of lung cancer, as early as the 1920s, the medical community proposed the relationship between smoking and lung cancer. However, it was not until the 1950s that British medical researchers conducted a large-scale survey of 59,000 British doctors and scientifically established From an epidemiological perspective, it has been irrefutably proven that smoking is the main cause of lung cancer.
★Four "killing" methods of cigarettes
1. E-liquid
Unfortunately, it is difficult to give a clear and concise answer as to what causes various uncomfortable reactions in the human body after smoking, but it is indeed related to e-liquid. The e-liquid in cigarettes is composed of thousands of chemical components, including corrosive and toxic gases such as various acids, ethylene glycols, ethanols and ketones, as well as hydrogen oxide and carbon monoxide.
2. Carbon oxide toxins
Carbon monoxide gas accounts for about 4% of cigarettes. Once it enters the lungs, it invades red blood cells and replaces them with oxygen. This toxic gas can deprive the heart and other body tissues of necessary oxygen and promote the deposition of cholesterol in blood vessels.
3. Nicotine
Nicotine itself is a toxic substance that initially stimulates the brain and central nervous system, and then has a depressive effect on them.
4. It is reported that 150,000 people die from smoking every year in the United States
If the loss of life is the second most important thing, then the fact that many ingredients in cigarettes are carcinogens is the most terrifying thing. Research shows that 30% of cancer deaths can be attributed to smoking, especially lung cancer, laryngeal cancer, mouth cancer, and esophageal cancer. In addition, smoking can cause bladder cancer, pancreatic cancer, and kidney cancer.
Among various cancers, the most deadly are lung and pancreatic cancer. According to the American Cancer Society, approximately 150,000 people die every year in the United States due to smoking.
The evidence that smoking kills people began in 1951, when the British Medical Association conducted a questionnaire survey among its 34,000 members who were addicted to smoking. During the subsequent ZO years, formal records were kept of these members' changes in smoking habits and causes of death. British doctors believe that addicted smokers under the age of 45 are 15 times more likely to die from heart disease than non-smokers. Smokers are at least three times more likely to die than non-smokers when it comes to lung cancer, respiratory disease and stroke. Many other cancers and diseases are also related to smoking.
In short, it is not difficult to see that this extensive and detailed research report, with its recorded number of patients and time span, strongly demonstrates that the opposition to smoking is not unreasonable.
★Smoking can easily cause sudden death
The so-called sudden death refers to sudden death or sudden death. It refers to death caused by cardiac arrest that occurs suddenly, unexpectedly, and is not caused by human factors. The time from onset to death of the patient often does not exceed 1 hour. Approximately 400,000 people die from sudden cardiac death in the United States every year, 70% of which are caused by heart disease.
After 12 years of research, scholar Framingham found that smokers are more than four times more likely to die suddenly from coronary heart disease than non-smokers, and the incidence of sudden death is also proportional to the number of cigarettes smoked per day. A follow-up study found that the rate of sudden death in the quit smoking group was 19%, while that in the continuing smoking group was 27%, a significant difference. Quitting smoking can reduce the recurrence rate of sudden death.
Experts point out that smoking can easily cause sudden death because harmful substances such as nicotine and carbon monoxide in smoke can easily induce coronary artery spasm, causing myocardial ischemia and hypoxia, resulting in unstable myocardial electrical activity. At the same time, nicotine and carbon monoxide can lower the threshold of myocardial ventricular fibrillation and make it more likely to cause ventricular fibrillation. In addition, it can also promote platelet aggregation hyperactivity and easily form intra-arterial thrombosis. These factors all contribute to the occurrence of sudden death. Therefore, it can be considered that smoking is an important risk factor for sudden cardiac death, and quitting smoking is one of the important measures to prevent sudden cardiac death.
★The lethality of nicotine
The nicotine in 1 cigarette can poison a mouse
The nicotine in 25 cigarettes can poison a cow< /p>
40-60 mg of nicotine can poison a person
About 1 million people die from smoking-related diseases in China every year, ranking first in the world
China Lung cancer mortality ranks first in the world, rising at an annual rate of 4.5%
The incidence of coronary heart disease among smokers is four times that of non-smokers
53.6% Non-smokers are harmed by passive smoking
A pack of cigarettes a day costs about 800 yuan a year and nearly 10,000 yuan in ten years
★Three major hazards of smoking
The smoke emitted by burning tobacco contains more than 20 kinds of toxins, and nicotine is the most harmful to life. From this point alone, smoking has three major hazards:
1. It can directly poison lives
Some people have obtained the following surprising results through animal experiments: In large horses, If you continue to inject nicotine for 8 days, you will die quickly; a lively dog ??can be killed without even a drop of nicotine injected into the vein; in addition, some animals can be found to have vasoconstriction or even sclerosis after long-term smoking. obvious trend.
2. It can destroy the nutrients of the human body
Smoking can prevent the body from absorbing vitamin C, and nicotine has a direct destructive effect on vitamin C. If the human body is deficient in vitamin C for a long time, there is a possibility of scurvy.
3. It can induce a variety of diseases
Because the smoke inhaled in the body has a malignant irritating effect on the respiratory tract, digestive tract and other organs, some people think it is gastric and duodenal ulcers. , respiratory tract infections and even triggering factors for cancers of the mouth, lips, tongue, esophagus, respiratory tract, etc.
From this point of view, smoking is harmful to human health but not beneficial. Therefore, we should try our best to quit smoking or smoke less. It is best for non-smokers not to get into this habit.
