Bad habits

Rejection of bad habits. Harm of smoking

Bad habits include alcohol abuse, smoking, drug addiction and substance abuse. All of them negatively affect human health, destructively affecting his body and causing various diseases. Tobacco smoking is one of the most common bad habits. Over time, it causes physical and mental dependence of the smoker.
First of all, the pulmonary system suffers from tobacco smoke, the lung defense mechanisms are destroyed, and a chronic disease develops – smoker’s bronchitis.

Part of the tobacco ingredients dissolves in saliva and, getting into the stomach, causes inflammation of the mucosa, which subsequently develops into gastric ulcer or duodenal ulcer.
Extremely harmful smoking affects the activity of the cardiovascular system and often leads to heart failure, angina pectoris, myocardial infarction and other diseases.


The radioactive substances contained in tobacco smoke can sometimes cause the formation of cancerous tumors. Tobacco smoke contains more than 3,000 harmful substances. It is impossible to remember all of them. But you need to know the three main groups of toxins:

  • resins. They contain strong carcinogens and substances that irritate the tissues of the bronchi and lungs. Lung cancer in 85% of all cases is caused by smoking. Cancer of the oral cavity and larynx also mostly occurs in smokers.

Tars are the cause of smokers’ coughs and chronic bronchitis.
Nicotine. Nicotine is a stimulant drug. Like any drug, it is addictive, addictive and addictive. Increases heart rate and blood pressure. Following brain stimulation, there is a significant decline up to depression, which causes a desire to increase the dose of nicotine. A similar two-phase mechanism is inherent in all narcotic stimulants: first excite, then deplete. Complete smoking cessation may be accompanied by a withdrawal syndrome lasting more often up to 2-3 weeks. The most common symptoms of nicotine withdrawal are irritability, sleep disturbance, tremors, anxiety, decreased tone.
All these symptoms do not pose a threat to health, they fade and disappear completely by themselves.

Re-intake of nicotine into the body after a long break quickly restores dependence.

Toxic gases (carbon monoxide, hydrogen cyanide, nitric oxide, etc.):

  • Carbon monoxide or carbon monoxide is the main toxic component of tobacco smoke gases. It damages hemoglobin, after which hemoglobin loses its ability to carry oxygen. Therefore, smokers suffer from chronic oxygen starvation, which is clearly manifested during physical exertion. For example, when climbing stairs or while jogging, smokers quickly develop shortness of breath.

Carbon monoxide is colorless and odorless, therefore it is especially dangerous and often leads to fatal poisoning. Carbon monoxide from tobacco smoke and car exhaust is the same substance with the same chemical formula – CO. Only in tobacco smoke it is more.

Hydrogen cyanide and nitric oxide also affect the lungs, exacerbating hypoxia (oxygen starvation) of the body.

Try to remember at least one number: tobacco smoke contains 384,000 MPC of toxic substances, which is four times more than in the exhaust of a car. In other words, smoking a cigarette for one minute is about the same as breathing direct exhaust gases for four minutes.

Tobacco smoke is harmful not only to the smoker, but also to those who are close to him. In this case, non-smokers experience headaches, malaise, exacerbate diseases of the upper respiratory tract, negative changes occur in the activity of the nervous system and blood composition. Second-hand smoke has a particularly harmful effect on children.

Important directions in the prevention of tobacco smoking are the improvement of morality, general and medical culture of the population and other measures of psychological and pedagogical influence.
Harm of alcohol.

Alcohol has a destructive effect on all systems and organs, as it dissolves well in the blood and is carried by it throughout the body.

Once in the stomach, ethyl alcohol has a negative effect on its mucosa, and through the central nervous system – on the entire digestive function. With frequent use of alcohol, this can lead to chronic alcoholic gastritis.

Alcohol has a very harmful effect on the liver, which is not able to cope with a large amount of alcohol. The work of the liver with overvoltage leads to the death of its cells and the development of cirrhosis.
Alcohol abuse leads to severe disturbances in the activity of the endocrine glands, primarily pancreas and sexual.

The main problem is that most of the alcoholic products produced by non-state enterprises contain a large amount of toxic substances.
