Let s all talk about the harm of smoking to us?

The damage of smoking to the mouth is the most easily ignored by smokers, most smokers' teeth are no longer pure and white, and the nicotine and tar in tobacco leave stains on the teeth, and a mouthful of yellow teeth has become a sign of smokers. More seriously, smoking can lead to periodontal disease, which not only causes gingivitis, but is also a predisposing factor for diabetes and oral cancer. It is recommended that smokers be friends with a dentist, have regular check-ups, clean their teeth regularly, and of course quitting smoking is the best protection for their teeth.

When smoking a cigarette, the inner diameter of the coronary artery shrinks by 35 and can last for 30 minutes. After smoking several cigarettes, the concentration of carbon monoxide in the blood increases, and the affinity between carbon monoxide and hemoglobin is very strong, thereby inhibiting the oxygen-carrying capacity of red blood cells, and reducing blood oxygen content and oxygen saturation. If a smoker has a pre-existing heart condition, it can trigger arrhythmia, angina pectoris, etc., and the frequency of attacks is twice that of non-smokers.

Smoking hurts the brain. Scientists from the University of Edinburgh in the United Kingdom and the University of Montreal in Canada have found that long-term smoking can thin the cerebral cortex, which dominates our cognitive functions and is associated with all memory, language, and perceptual behaviors. In other words, smoking can not only cause cerebrovascular damage, but also may cause serious damage to your language and memory, and Alzheimer's disease may not be far away from you.

Cigarettes contain the toxic nicotine, also known as nicotine. Nicotine is more harmful to the human body, and if an individual injects 50 mg of nicotine, it can kill people.

Smoking causes cancer. Statistics show that smoking can cause 30% of cancers. Eighty-five percent of lung cancers are smoking-related, and smokers are 15 times more likely to have lung cancer than non-smokers.

Smoking is harmful to people's health, and this is a probability that has been observed through a large number of clinical experimental studies. Not everyone who smokes is healthier than non-smokers, just a very small few. If one person smokes, many people will be exposed to second-hand smoke, which is more harmful.

Statistics show that the incidence of myocardial infarction in smokers is 2 6 times that of non-smokers, and 30% and 40% of the deaths from cardiovascular diseases are caused by smoking, which is an independent risk factor for the incidence of coronary heart disease and hypertension.

Cigarettes carry carbon monoxide, nicotine, tar, etc., which are dangerous to the human body, and long-term smoking can reduce the body's own immunity!

It is a well-known fact that smoking is harmful to health. Among the top ten causes of death among Chinese released by the Ministry of Health, the top four diseases, namely malignant cancer, heart disease, cerebrovascular disease, and respiratory disease, are all related to smoking.

Long-term smokers, no matter how healthy you seem, in fact, the body has already been damaged, it is recommended to smoke less, the best way to quit.

Smoking is harmful to health.

There are many harms of smoking, not only harmful to human health, but also to have a negative impact on society. The main harms of smoking are as follows:

1. Cause lung disease. Smoking is easy to cause laryngitis, tracheitis, emphysema and other diseases, and is the biggest cause of COPD and lung cancer.

2. Smoking can damage blood vessels, easily lead to arteriosclerosis, and cause cardiovascular and cerebrovascular diseases, such as cerebral infarction, cerebral hemorrhage, etc.

3. It is worth noting that smoking not only endangers one's own health, but also makes the people around him passively smoke, causing the same impact.

Yes, smoking is very harmful.

Smoking has the following harms:

1.Tobacco smoke contains hundreds of harmful substances, among which 69 known carcinogens can directly cause many cancers such as oral and pharyngeal malignant tumors, laryngeal cancer, esophageal cancer, gastric cancer, liver cancer, pancreatic cancer, kidney cancer, bladder cancer, cervical cancer, etc.

2.Smoking can lead to chronic obstructive pulmonary disease and cardiovascular and cerebrovascular diseases, and is one of the main causes of coronary heart disease, stroke, aortic aneurysm and peripheral vascular disease.

3.Smoking is an independent risk factor for cardiovascular and cerebrovascular diseases.

Exposure to secondhand smoke can also cause serious harm to the body, leading to lung cancer, respiratory diseases, cardiovascular and cerebrovascular diseases, and pregnant women's exposure to secondhand smoke can lead to reduced birth weight, premature birth and sudden infant death syndrome. The harm caused by children's exposure to secondhand smoke is also not to be underestimated.

What are the dangers of smoking? Star Awareness Project

1. Carcinogenicity.

Smoking is one of the important pathogens of lung cancer, especially squamous epithelial cell carcinoma and small cell undifferentiated carcinoma. Smokers have a 13-fold higher risk of developing lung cancer than non-smokers, and 45 times more likely than non-smokers if they smoke more than 35 cigarettes a day. Lung cancer mortality rates are 10 to 13 times higher in smokers than in nonsmokers.

About 85% of lung cancer deaths are caused by smoking. Smokers are also exposed to chemical carcinogens such as asbestos, nickel, uranium and arsenic at higher risk of developing lung cancer.

2. Effects on heart and cerebrovascular.

Many studies believe that smoking is the main risk factor for many cardiovascular and cerebrovascular diseases, and the incidence of coronary heart disease, hypertension, cerebrovascular disease and peripheral vascular disease in smokers is significantly increased. Statistics show that 75% of patients with coronary heart disease and hypertension have a history of smoking. The incidence of coronary heart disease in smokers is 3 5 times higher than that of non-smokers, the mortality rate of coronary heart disease is 6 times higher than that of the latter, and the incidence of myocardial infarction is 2 6 times higher than that of the latter.

3. Impact on the respiratory tract.

Smoking is one of the main causes of chronic bronchitis, emphysema, and chronic airway obstruction. Smokers suffer from chronic bronchitis 2 to 4 times more often than nonsmokers, and it is proportional to the amount of cigarettes smoked and the number of years smoked, and patients often have chronic cough, sputum production, and dyspnea with activity. Pulmonary function tests show airway obstruction, decreased lung compliance, ventilatory and diffusion functions, and decreased arterial partial pressure of oxygen.

Even young, asymptomatic smokers have mild hypofunction of the lungs. COPD predisposes to spontaneous pneumothorax. Smokers often suffer from chronic pharyngitis and vocal corditis.

4. The harm of smoking to women.

Smoking is more harmful to women than men, and women who smoke can cause menstrual disorders, difficulty conceiving, ectopic pregnancy, low estrogen, osteoporosis, and early menopause. Smoking in pregnant women is predisposed to spontaneous miscarriage, fetal growth retardation, and low birth weight.

5. Passive smokers.

It refers to people who live and work around smokers and unconsciously inhale smoke dust particles and various toxic substances. According to an international sample survey, 50% of patients with cancer caused by smoking are passive smokers. A large number of epidemiological surveys have shown that the prevalence of lung cancer in wives whose husbands smoke is 1,6,3,4 times higher than that of non-smokers.

The whole fibrosis of your lungs is like wood and is not active at all The second is cardiovascular, smoking can lead to cardiovascular blockage, and the third is that smoking will make you numb and dependent, and even many people will tremble, unable to control their body, and will cause stomach ulcers and infertility in the reproductive system.

Smoking can cause lung cancer, and many people get lung cancer, and the number of people who are saved dies.

Smoking has been around for hundreds of years since Christopher Columbus discovered the New World. The harm of smoking is not only harmful to human health, but also has a negative impact on society. People live to breathe, exhale carbon dioxide in the body, inhale oxygen in the air, and carry out metabolism to maintain normal life activities, non-smokers can inhale a lot of fresh air every day, while people who smoke regularly, but do not enjoy the blessings of nature, inhaling not fresh air, but toxic gases polluted by smoke.

Tobacco contains the toxic nicotine, also known as nicotine. 1 gram of nicotine can poison 300 rabbits or 500 mice. If you inject 50 mg of nicotine, it can be fatal.

Smoking is the most harmful to the respiratory tract and can easily cause cough diseases such as laryngitis, tracheitis, and emphysema. When you smoke, smoke enters through the mouth, through the throat, trachea, bronchi, and into the bloodstream. Smoking increases the risk of cancer when men lose their Y chromosomes.

I'm also a smoker and want to know about the dangers of smoking. I know that smoking is not good for my health, but I still smoke.
