What are the harms of smoking to the human body

I believe that many people have this confusion in real life, that is, no matter where they go, they can smell cigarettes, and it seems that there are always people smoking around them. We can all see a very conspicuous sentence on the cigarette box: Smoking is harmful to health. More and more people are addicted to cigarettes, and younger and younger children are starting to smoke. What are the harms of cigarettes to the human body? What destructive effects does it have on the human body? Let’s take a look together.

Tobacco smoke contains at least three dangerous chemicals: tar, nicotine and carbon monoxide. Tar is a mixture of several substances that condenses into a viscous substance in the lungs. Nicotine is an addictive drug that is absorbed through 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 four times more likely to die from esophageal cancer; he is twice as likely to die from bladder cancer; and he is twice as likely to die from heart disease. Smoking is the main cause of chronic bronchitis and emphysema, and chronic lung disease itself increases the risk of pneumonia and heart disease, and smoking also increases the risk of high blood pressure.

Smoking is harmful to health, this statement is verified between the lines above. Tobacco is harmful to the human body and has no benefits. The toxic ingredients in tobacco can even cause fatal harm to people. This reminds us that smoking is actually corroding our bodies and consuming our lives. It's not worth it to gamble with your life. Therefore, in today's society where people focus on health preservation, we hope that more and more people can stay away from cigarettes and minimize the harm of cigarettes to the human body.
