Many people smoke for pleasure, for social reasons, such as peer pressure or simply to satisfy their addiction. Initially, smoking was common only among natives of North and South America. Later, it was taken to the rest of the world through trade and exploitation of the Americas.
Other important information
In addition to tobacco, cigarettes contain many other harmful substances, including nicotine, which causes addiction.
Nicotine has an illusory beneficial effect early on, as it stimulates attention, memory and generates a moderate state of euphoria.
However, once smoking becomes chronic, nicotine only attenuates such uncomfortable withdrawal symptoms as mental confusion, nervousness, anxiety, insomnia, and depression.
In chronic users, such symptoms begin quite quickly, approximately 30 minutes after each dose.
Another harm to nicotine is that it causes metabolism disorders and inhibits appetite.
Medical research has found that chronic smokers are much more likely to get diseases such as lung cancer, emphysema, and cardiovascular disease.
Faced with all these harms caused by cigarettes, many countries have restricted their sale by forcing manufacturers to put prominent warnings on their packaging.
In order to discourage smoking, other measures have also been taken by many rulers, such as restricting or even banning smoking in restaurants, shopping malls and many other public places.
Diseases caused by smoking: the harms of smoking
Smoking can cause many types of cancer, such as lung, kidney, larynx, head and neck, bladder, esophagus, pancreas, and stomach cancer.
In addition, there is evidence to suggest that smoking may lead to a higher risk of leukemia, liver, colon or rectal cancer, congenital problems in children of women who have not stopped smoking during pregnancy, impotence, among many others.
