Early initiation of smoking during life and smoking with higher tar grades increases the risk of developing these diseases.
The World Health Organization estimated that smoking caused 54 million deaths in 2004 and 100 million deaths during the 20th century, which is much more than AIDS, tuberculosis, traffic accidents and suicides combined.
15,000 smokers die in Australia every year, and this issue costs the government 30 billion Australian dollars (equivalent to 19 billion pounds).
Many researches have been conducted in the world that indicate the harmfulness of smoking.
However, cigarette manufacturing companies call these projects baseless and unproven and continue to widely advertise cigarettes in different countries of the world.
In most of the countries of the world, except for the free zones, a heavy tax is charged on cigarettes (up to several times the initial price) and they try to use this money to improve the health of the people of that country.

In the 1930s, the association between smoking and lung cancer was not established, and the causal relationship between smoking and cancer was not proven until 1957 in England and 1964 in America. Surprisingly, even more than this time, cigarettes were considered to have beneficial effects. And cigarettes were even listed in pharmaceutical encyclopedias until 1906, and even doctors recommended smoking to patients who had a cough, caught a cold, or had tuberculosis.
Nazi German researchers were the first to prove the link between lung cancer and smoking.

48 hours after the last cigarette consumption, the sense of taste and smell returns to the normal level.
2 weeks to 3 months after stopping smoking, blood flow improves and pulmonary function improves.
1 to 9 months after stopping smoking, the lungs begin to rebuild themselves.
The cilia also regenerate themselves. Cough and shortness of breath are reduced.
The cilia (hair-like structures that remove phlegm and secretions from the lungs) become normal, and the phlegm discharge and lung cleaning become better and, as a result, the possibility of infection decreases.
1 year after stopping smoking, the risk of coronary heart disease is reduced by half.
From 5 to 15 years after stopping smoking, a former smoker has the same risk of stroke as a non-smoker.
10 years after quitting smoking, the chance of dying from lung cancer in a quitter is half that of a smoker.
15 years after a former smoker quits, the risk of coronary heart disease is the same as that of a non-smoker.
