Today, we do not see any country where there is not a certain percentage of smokers. The trend has spread widely over the years across the world. Smoking is a trend that did not start in recent years, but its history dates back to early 5026 BC. Surprisingly, it was first used only for medicinal purposes, as opium was considered to have certain medical properties. (History of Smoking) One of the reasons behind this widespread use of smoking is the depiction of smoking in films and on television. Undoubtedly, this encouraged people to smoke and created a concept in young and immature minds that one “looks cool” when one smokes. . Smoking leads to many types of cancers and other horrible diseases. Tobacco smokers are very likely to switch to stronger drugs. Many cigarette companies managed to obtain a deadline for advertising their products on television, but with the Tobacco Framework Agreement of 1998, television advertisements for cigarette companies were banned. Smoking is a harmful practice which, even if carried out by individuals of their own free will, affects the environment and therefore must be prohibited. Ever since people started smoking, researchers have been researching its harmful effects on the human body. Fritz Lickint, in 1929, presented formal statistical evidence that smoking leads to lung cancer. This resulted in a movement in Nazi Germany, which strongly opposed smoking. As smoking is considered to be the main cause of cancer, there are different types of cancer that can attack a human being at any time during the period of smoking. The most common cancer that traps people is called lung cancer. Today, around 90% of lung cancers are caused by smoking.
