The inside of the lungs will be destroyed, the bronchi will narrow and it will be difficult to breathe out. In many cases, cough and sputum are progressive diseases that last long.

If a person who have asthma smokes, it is considered to occur COPD with high probability.



Stomach cancer

People who are liable to stomach cancer are considered to be infected with Helicobacter pylori, but it is thought that people who smoke are also liable to suffer.

Stomach acid secreted from the stomach and defenses for defending the stomach are out of balance so that stomach walls are damaged, and it is causing abdominal pain or bleeding. Smoking has an adverse effect such as increasing secretion of gastric acid and increasing the attacking factor to the stomach wall.




Duodenal ulcer


Due to smoking, symptoms similar to stomach ulcers occur in the duodenum. Because the wall of the duodenum is thin, it is easy to progress deeply. Symptoms such as the blood vessel breaking out and the hole becoming easy to open appear.

An artery is blood vessel that sends blood from the heart to every corner of the body, and it repeats expansion and contraction according to blood flow.

Arteriosclerosis is a disease in which this blood vessel narrows or hardens due to something, which means that blood does not reach the part where it is needed, and suddenly its flow may cease.  If it occurs in the artery of the brain, it leads to an episode of cerebral infarction.

By virtue of the carbon monoxide contained in tobacco, the blood vessel wall is damaged, so smokers are more likely to suffer from this disease.





Angina pectoris


When blood vessels supplying blood to myocardium called coronary artery becomes narrow, myocardial blood will run short. This disease is a seizure in which a pain that causes the chest to be tightened tightly by it.

It is thought that tobacco smoke causes blood vessels to contract and causes this disease.

There are many other things that can be thought of as a bad influence

 on the human body by tobacco than those shown here.



Even though you know that you should not smoke.

At that moment, smoking for smokers may be more important than their own health.

In terms of the health of the smokers themselves, we think that it is self-responsibility not to smoke or to smoke.

Therefore, we can not give any opinion on the health of smokers.



However, smokers think that you should firmly recognize the negative impact of tobacco

on the health of the surrounding people.

Tobacco smoke indirectly makes non smokers sicker (For more information please refer to secondhand smoke).

We think that smokers should smoke in a way that does not cause

health hazards to non smokers, well knowing that.

If such efforts are continued, non smoker’s image of smoking will change little by little,

and will not they approach society where people can coexist with tobacco?
