The harm of smoking to the human body
Even a single smoked cigarette causes abnormal reactions in the body - heart rate increases, blood pressure rises, blood vessels narrow, which after a while becomes the cause of blood clots. The airways are also narrowed, provoking sputum production and asthmatic attacks. Nicotine, inhaled into the lungs along with cigarette smoke, provokes the formation, division and multiplication of cancer cells. First of all, the lungs and the cardiovascular system suffer from it.
Nicotine has a most destructive effect on the mucous membrane of the oral cavity, causing the development of malignant tumors. Doctors believe that smoking to a large extent provokes pancreatic cancer, which is quite difficult to remove even with surgery. The effects of nicotine poison also affect vital organs such as the eyes.
It is difficult to underestimate the harm that smoking causes a person's reproductive abilities, it is the cause of female and male infertility, impotence. A huge amount of toxic substances entering the body threaten the health and development of the unborn child, making him a passive smoker even before birth.
The dangers of smoking for children and adolescents
If adults make their own choice, then children most often suffer from secondhand smoke, inhaling the smoke from the cigarettes that smoke around them. Teenagers, seeing the example of adults and following a silly fashion, also begin to smoke, wanting to appear more mature.
Cigarettes act even more destructively on an unformed organism. The combustion products of tobacco negatively affect the hormonal status, the endocrine glands, including the sex glands. Teenage girls who smoke are one and a half times more likely to complain of irregular and painful menstruation than those schoolgirls who did not succumb to this habit. The earlier a teenager starts smoking, the more likely it is that by the age of 30 he will become disabled.
