On the dangers of smoking

Smoking is one of the most significant threats to human health.
According to the World Health
Organization, tobacco causes nearly 7 million deaths each year, of which more than 6 million occur among users and former tobacco users, and more than 890,000 among non-smokers exposed to second-hand smoke. Unless urgent action is taken, the number of annual deaths could exceed 8 million by 2030.
On the effects of smoking on the body
Smoking tobacco leads to dependence.
Smokers quickly form an addiction to the nicotine contained in tobacco leaves, which causes a strong need to smoke again and again.
When a person tries to quit smoking, he or she may have withdrawal symptoms, including:

• irritability
• decreased concentration
• trouble sleeping
• increased appetite
• powerful cravings for tobacco.
In addition to nicotine, a number of other dangerous chemicals are found in tobacco smoke, such as tar, radioactive polonium, arsenic, lead, bismuth, ammonia, organic acids. Cases of acute poisoning with these substances are practically not observed due to the fact that they enter the body slowly, dosed, but these substances lead to a gradual deterioration in health.
When burning 20 g of tobacco, on average, the following is formed:
0.0012 g of hydrocyanic acid;
About 0.0012 g. hydrogen sulfide;
0.22 g pyridine bases;
0.18 g. nicotine;
0.64 g ammonia;
0.92 g. carbon monoxide;
At least 1 g of concentrate from liquid and solid products of combustion and dry distillation of tobacco
Many smokers believe that smoking a cigarette with a filter is safe, but this is not the case. If the absorbers and filters provided complete protection against harmful substances, then they would absorb nicotine itself, in which case the effect of smoking would not be felt. Light cigarette smokers also believe that smoking light cigarettes has minimal effects on the body.
The harm caused by smoking any cigarettes is the same for all smokers.
In addition to the smoker himself, those who are around suffer - the so-called passive smokers.
Long-term smoking leads to diseases of various organs and systems.
What damage does tobacco use cause in general to health?
Smoking increases the risk of death from cancer and other diseases in cancer patients and healthy people.
Smoking can cause an oncological process in any organ:
• bladder
• blood (acute myeloid leukemia)
• cervix
• intestines • esophagus

• kidneys and ureters
• larynx
• liver
• oral cavity (throat, tongue, soft palate and tonsils)
• pancreas
• stomach
• trachea, bronchus and lungs

Smoking harms the heart and circulation, increases the risk of coronary heart disease, stroke, peripheral vascular disease (damaged blood vessels) and cerebrovascular diseases (damaged arteries that supply the brain with blood).
Carbon monoxide from smoke and nicotine increase the load on the heart, causing it to work faster. They also increase the risk of blood clots.
In fact, smoking doubles the risk of heart attack, angina pectoris. Smokers have a double risk of death from coronary heart disease than non-smokers.
Smokers who smoke 5 or fewer cigarettes a day may have early signs of cardiovascular disease.
If you quit smoking
A year after quitting smoking - the risk of developing cardiovascular diseases is halved, after 15 years the risk is similar to the risk of someone who has never smoked
