The specific disadvantages of smoking, what are the disadvantages of smoking

1. Effect on cardiovascular and cerebrovascular diseases.

Smoking is an important cause of cardiovascular and cerebrovascular diseases such as hypertension and coronary heart disease, and statistics show that 75% of patients with coronary heart disease and hypertension have a history of smoking.

Nicotine and carbon monoxide in smoke are recognized as harmful substances, and smoking can cause damage to vascular endothelial cells, causing an increase in cholesterol, which leads to constriction of peripheral blood vessels and coronary arteries, resulting in myocardial hypoxia. Therefore, smokers with cardiovascular disease are more likely to develop irregular heartbeats and have an increased risk of sudden death.

2. 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 non-smokers, patients often have chronic cough, phlegm and dyspnea during activity, and even young asymptomatic smokers will have mild pulmonary hypofunction.

3. Carcinogenicity.

Lung cancer is the most directly related cancer to smoking, and studies have shown that if you smoke more than 35 cigarettes a day, you are 45 times more likely to develop lung cancer than non-smokers. Smoking reduces the activity of natural killer cells, thereby impairing the body's ability to monitor, kill, and eliminate tumor cell growth, which further explains why smoking is a high risk factor for many cancers.

Smoking will not only cause damage to the airways, but also cause cardiovascular and cerebrovascular diseases, lung tumors, etc., and the decline in lung function in smokers is 20% to 30% faster.

Say a few ready-made.

1.Affects intelligence.

2.Affects sexual function.

3.Affects lifespan.

4.Affects all organs of the body (mainly the heart, lungs, kidneys, liver), is this still not easy to understand?

Smoking - throat - trachea - lungs - blood - heart - whole body.

Smoking is not good at all, if your dad smokes, all his physical problems are related to smoking.

Smoking is a serious harm to health, smoke less cigarettes a day, and live a long and healthy life!!

That is, you will die sooner than you who don't smoke.

1. The harm of smoking.

Scientists estimate that 3 million people die from smoking each year in the world, and 10 million by 2025, meaning that smoking will be a major concern in the next century.

Cigarette smoking is an independent factor in the development of proteinuria. The occurrence and development of proteinuria in young diabetic patients, and the exacerbation of kidney disease are related to smoking, and proteinuria, proteinuria and retinopathy progress faster than those of non-smokers, and proteinuria in patients who stop smoking improves rapidly.

The most terrible is that 90% of lung cancer patients are caused by smoking, because smoking contains benzene and tar, and there are many radioactive substances that can cause cancer. Past studies have shown that at least 60% of bladder cancer cases in men in Western countries are caused by smoking, as well as oral and laryngeal cancers. Expired tobacco products are at greater risk of cancer because they contain mold.

According to the results of expert research and observation, various diseases caused by smoking are not irreversible, and as long as you quit smoking, you can improve or be cured and restore your health.

2. Harmful effects of passive smoking.

The so-called "passive smoking" means that the smoker is surrounded by non-smoker victims, including their parents, husbands, wives and children who live together. "The World Health Organization points out that a long-term smoker, and a non-smoker around him for 1 hour in a room with smoke, is equivalent to smoking a cigarette.

It seems that only smokers who wish to enjoy the freedom to smoke consciously respect the freedom of non-smokers to refuse passive smoking, and appeal for the victims of passive smoking, which is also a part of the proposal for socialist spiritual civilization.

It's good to smoke less, it's not good for your family, it's not good for your lover, and it's also very harmful to smoke twice.

It doesn't hurt to remind yourself that it's okay to be alone and get used to loneliness.

There are a lot of disadvantages, and it's good to know that there are disadvantages.

There are many harms of smoking, smoke contains tar (carcinogen), nicotine (addictive), carbon monoxide is produced when burning, and hemoglobin in the blood is combined to make oxygen not get **, so it produces dizziness.

According to the information: nicotine lifted by a cigarette can poison a person;

Nicotine extracted from a pack of cigarettes (20) can poison a cow.

Care for life, no smoking! Remember!

My experience is: 1. People who smoke do not suffer from laryngitis (except for colds). I started smoking because of laryngitis for a long time.

As soon as the smoke stops, the laryngitis will come immediately. 2. Refresh your mind. For people who use their brains, cigarettes do bring inspiration, which is why people who write articles generally smoke.

3. Relieve the greasy taste of the mouth. Therefore, there is a saying that "a cigarette after a meal is like a living fairy". 4. The role of **.

The reason for the estimation is the same as point 3: breaking down fat. It is evident that fat people who smoke are significantly less likely than fat people who do not smoke.

5. Life extension. If you look around, you will know that when one of the two elderly people can smoke and the other can't smoke, those who die early generally don't smoke. 6. In communication, it helps to reduce estrangement and bring the relationship closer.

6. Provide tax sources for the state. 7. Provide a justifiable reason and means for the corrupt.

As for the disadvantages, 1. When you are with people who don't smoke, others will think it smells. 2. Non-smokers say that they will develop respiratory diseases, and some say that they will develop cancer.

For good and bad, just want to say: someone told you that you should have lived to be 100 years old, because you only lived 90 years old because you smoked. Do you believe it or not?

I'm telling you, you can live 90 years without smoking and 100 years if you smoke. Do you believe it or not? For the sake of these 10 years, no one knows whether it will exist or not, what are you willing to choose?

Smoking, old fast.

Smoking, black lungs.

Smoking, heart disease.

Smoking, emphysema.

Smoking, yellow teeth.

Smoking, black nails.

Smoking can give people around you a chance of asthma.

And finally, a person who smokes is very disgusting if he sneezes.

Because the cilia of the trachea are occupied, they can't stick to the airborne bacteria, and when the smoker sneezes, they spit it out -- and some are even more disgusting, and they may spit out the tar. Black, slimy.

In fact, smoking is no different from smoking pesticides-,- both have nicotine.
