Tobacco smoking is one of the most common habits in the world, and also one of the risk factors for many diseases. It can lead to serious diseases such as lung cancer, cardiovascular disease and other health problems. Smoking can be compared to a drug. Only the narcotic effect of this drug affects not only the body, but also reduces the clarity of thinking, spoils diction, and generally has a negative effect on speech. Smoking slows down movements and slows down a person’s mental activity. The production of hormones increases, libido is disrupted, complexion deteriorates, the skin becomes older and saggy, and wrinkles appear on the face. A smoker's skin is always gray, without liveliness. Over time, it is destroyed from the inside, and cancer appears. The digestive system also suffers, causing ulcers on the mucous membrane of the esophagus, stomach, and intestines. Enteritis, colitis. Appetite decreases. Therefore, the smoker loses sleep and has many minor health problems, which throughout the year, poisoning the body with small portions of harmful substances, gradually develop into a severe stage of the disease. Also, over time, a person who smokes begins to get a lot of colds. Insomnia - the appearance of nervousness, irritability. Increased risk of infection with influenza viruses in winter, i.e. flu. All this is caused by the fact that smoke particles in the air have a much stronger harmful effect on human health. Getting rid of all these diseases is worth the effort and very much depends on the desire of the smoker himself to quit this bad habit.
