For many people smoking is a trend, or a way of attracting attention so people will think better of them, at least that is how the smoker feels. But in many cases in this corrupt day and age the smoker is an addict and is the dependent of the vicious drug nicotine. Nicotine is the most addictive drug in the world, and is abused by ignorant human beings through the use of cigarettes. Personally nicotine is my worse enemy and if were flesh and bones I would destroy it, because of the fact that is has taken my beloved father which I love more than anything in this world and turned him into an addict. This paper has helped turn the anger I had for my father because of his smoking, into pity and sorrow. For the fact that because of the paper I now have an understanding of why my father is addicted. What he feels and goes through every time he tries to quit and does not succeed why he can't quit, and lastly why de has become dependent of the life threatening drug nicotine.

While some condemned tobacco, others praised it for its supposed medicinal qualities. Doctors prescribed tobacco preparations to treat everything from cancer to dog bites. Seventeenth-century chemists were the first to understand the power of tobacco's active ingredient, nicotine. Experiments on animals showed some of the powerful effects. By the end of the century, tobacco was no longer considered a helpful medicine. But it was still widely smoked for pleasure and recreation. The numbers of smokers worldwide continued to grow.

The health effects of tobacco are the effects that use of tobacco has on human health, and concern about health effects of tobacco has a long history. Research has focused primarily on cigarette tobacco smoking. In 1950, Richard Dollpublished research in the British Medical Journal showing a close link between smoking and lung cancer. Four years later, in 1954, the British Doctors Study, a study of some 40,000 doctors over 20 years, confirmed the suggestion, based on which the government issued advice that smoking and lung cancer rates were related.

Tobacco use is the single greatest cause of preventable death globally. As many as half of people who use tobacco die from the results of this use. The World Health Organization (WHO) estimates that each year tobacco causes about 6 million deaths (about 10% of all deaths) with 600,000 of these occurring in non smokers due to second hand smoke. In the 20th century tobacco is estimated to have caused 100 million deaths.Similarly, the United States Centers for Disease Control and Prevention describes tobacco use as "the single most important preventable risk to human health in developed countries and an important cause of premature death worldwide."

Tobacco use leads most commonly to diseases affecting the heart, liver and lungs. Smoking is a major risk factor for heart attacks,strokes, chronic obstructive pulmonary disease (COPD) (including emphysema and chronic bronchitis), and cancer (particularly lung cancer, cancers of the larynx and mouth, and pancreatic cancer). It also causes peripheral vascular disease and hypertension. The effects depend on the number of years that a person smokes and on how much the person smokes. Starting smoking earlier in life and smoking cigarettes higher in tar increases the risk of these diseases. Also, environmental tobacco smoke, or secondhand smoke, has been shown to cause adverse health effects in people of all ages Tobacco use is a significant factor in miscarriages among pregnant smokers, and it contributes to a number of other health problems of the fetus such as premature birth, low birth weight, and increases by 1.4 to 3 times the chance of sudden infant death syndrome (SIDS)Incidence of erectile dysfunction is approximately 85 percent higher in male smokers compared to non-smokers.

Several countries have taken measures to control the consumption of tobacco with usage and sales restrictions as well as warning messages printed on packaging. Additionally smoke free laws are useful, do not have negative economic effects for restaurants or bars and help people who smoke to quit.Taxing tobacco products in an effort to increase the price is also effective, especially in developing countries. Tobacco smoke contains more than fifty chemicals that cause cancer. Tobacco also contains nicotine, which is a highly addictive psychoactive drug. When tobacco is smoked, nicotine causes physical and psychological dependency. Cigarettes sold inunderdeveloped countries tend to have higher tar content, and are less likely to be filtered, potentially increasing vulnerability to tobacco smoking related disease in these regions.
