Why smoking...?

	Nowadays it would be unheard of for people not to smoke. Smoking is a part of everyday life, although, believe it or not, it has only recently become so. There are over one thousand million smokers throughout the world, which is an astonishing number, considering the harm smoking does to your body, which we are all well aware of. With this in mind, the question "why do people smoke?" is a really complicated one, that is now being explored much more in depth by many of the world's doctors and scientists.
It has only recently been proved that smoking causes lung cancer amongst other serious diseases and that passive smoking is also harmful for those that do not smoke. Thus, more and more governments are trying to make people aware of the health risks and consequences of smoking. Some governments have even banned smoking in all indoor public places. Cigarettes are widely available and in many countries fairly inexpensive to buy. For this reason, buying cigarettes is no longer a luxury only for those who can afford to buy them, but a product that is widely attainable by most people.
