In 1943, two researchers at the University of Jena, Eberhard Schairer and Eric Schöniger, would confirm Muller’s findings. Muller would famously be remembered for stating, “Tobacco was an important cause of lung cancer”(32).
In 1922, Angel Honorio Roffo began investigating the etiology of lung cancer. Roffo, an Argentinian scientist working from his lab in Buenos Aires, was the first to use experimental animal studies to investigate tobacco’s role in cancer. At the time of Roffo’s research, many in the scientific community felt that if tobacco caused cancer it would be due to a simple constituent in the tobacco, for example nicotine. By 1940, Roffo believed that tobacco’s etiological role in cancer was best explained by the production of a complex plume of

Medical historians often consider the evidence for and against the tobacco hypothesis in terms of what was known prior to 1950. Although there was a rather robust body of medical literature against tobacco prior to 1950, it was not until Ernest Wynder and Evarts Graham published their now famous case-control study, Tobacco Smoking as a Possible Etiologic Factor in Bronchiogenic Carcinoma, that the western historians took note. Wynder and Graham’s case-control study compared over 600 cases of bronchogenic cancer to 780 cancer free controls. The results of this study found a very significant association between cancer cases and tobacco smoking. Wynder and Graham concluded that it appeared the incidence of lung cancer was due to some exogenous factor(s), which should include tobacco smoke(36). It is worth mentioning that Evarts Graham was a highly respected thoracic surgeon and cigarette smoker, who initially did not believe tobacco smoke was causally related to lung cancer. In a bit of tragic irony, Graham died of lung cancer in 1957 following his conversion to the tobacco hypothesis, which was based upon his aforementioned case-control
Tobacco is connected with a number of negative effects in humans and a few other organisms. For example, the long list of negative effects range from birth defects and lessened lung capacity, to sexual impotence. All of the previously mentioned result from extended tobacco exposure in varying mediums and although they are negative effects associated with tobacco, it has also been proven that tobacco to acts as a stimulant to some animals (Nice 135). In studying how tobacco effects the body of any living being and its uses, over time new developments may progress that would allow us to use tobacco only for its positive effects while bypassing its negative ones.
The tobacco industry seems like a beneficial addition to our economy. It has basically been a socially acceptable business in the past because it brings jobs to our people and tax money to the government to redistribute; but consider the cost of tobacco related treatment, mortality and disability- it exceeds the benefit to the producer by two hundred billion dollars US. (4) Tobacco is a very profitable industry determined to grow despite government loss or public health. Its history has demonstrated how money can blind morals like an addiction that is never satisfied. Past lawsuits were mostly unsuccessful because the juries blamed the smoker even though the definition of criminal negligence fits the industry’s acts perfectly. Some may argue for the industry in the name of free enterprise but since they have had such a clear understanding of the dangers of their product it changes the understanding of their business tactics and motives. The success of the industry has merely been a reflection of its immoral practices. These practices have been observed through its use of the media in regards to children, the tests that used underage smokers, the use of revenue to avoid the law, the use of nicotine manipulation and the suppression of research.
During the time period 1450 to 1750, the world went through major change and development. Nomadic power declined, and European Kingdoms became world powers. A world trade network was set up as contact amongst nations increased immensely. A population boom occurred throughout the world. Many civilizations that were once isolated were brought into the world economy. The Americas unknown until Christopher Columbus’ voyage in 1492 became a major part of the world economy as many European nations colonized much of the land. Large sea trade arose during this time period first by the Portuguese and Spanish and later by the English, French and Dutch. As European countries began exploring the Americas, an exchange of crops, animals, raw materials, diseases and new ideas were exchanged between the Americas and the rest of the world. This is known as the Columbian Exchange. One major component of the Columbian Exchange was the discovery of tobacco. Tobacco was first discovered in the Americas and became as cash crop. It was imported back to Europe, where it became vastly popular. As many middle class Europeans people began smoking, the demand for more tobacco from the Americas increased; colonies were set up to produce tobacco. With the demand for tobacco so high, labor was needed to farm the crop causing slaves to be imported.

Tobacco smoking is linked to at least 17 different types of cancer such as lung cancer and oral cancer, and it leads to more than six million deaths per year. The smoke itself is made up of a large mixture of chemicals, at least 60 being carcinogens, substances that can lead to cancer. The way in which these substances cause cancer is by damaging the DNA which can lead to mutations in the cancer gene. The carcinogen
Cancer of the lung was nearly nonexistent in the early 1900’s. By the middle of the 20th century an epidemic became apparent throughout the United States and the rest of the world. It is primarily correlated with the widespread abundance of cigarette smoking in the world. The tobacco industry has multiplied its production immediately prior to World War I. There was a typical 20 to 30 year lagging period between the initiation of cigarette smoking and the actual tumor formation in the lungs. Lung cancer is the cancer that originates in the tissues of the lungs. It occurs when cells in the lung start to grow rapidly in an uncontrolled manner. Lung cancer can start anywhere in the lungs and affect any part of the respiratory system. Most of all lung cancer cases start in the lining of the bronchi (health-cares.net, 2005). It is the leading cause of all cancer deaths in the world. During this time the tobacco companies would continue to say that cigarette smoking was not addictive and did not cause any type of cancer. Even with all evidence in the world today about tobacco causing cancer, Tobacco companies still remain the most profitable business in the world. Lung cancer is very common in both women and men. Women account for about 40 percent of the lung cancer cases in the world. Women who smoke are more than twice as likely to develop lung cancer as those of men who smoke (Tavor, 2005).
Encyclopaedia of Children’s (2013) stated that smoking is a form of inhalation of smoking from different forms of tobacco which include cigarettes, pipes, and cigars. Cancer Research (2012) and the World Health Organisation (2013) have confirmed that most tobacco products contain very high level of nicotine which can have additive effect and are made from tobacco leaf which are s...
To begin, people can receive certain forms of cancer if they use tobacco products. When discussing health problems of smoking, the author writes, “Smoking harms nearly every organ in the body” (Harms of Smoking and Health Benefits of Quitting). Scientists have conducted research and have concluded that using a tobacco product damages cells. The damaged cells become mutated and form cancer cells. The author goes on to explain, “Among the 250 known harmful chemicals in tobacco smoke, at least 69 can cause cancer” (Harms of Smoking and Health Benefits of Quitting). These harmful chemicals are catalysts for many types of cancer. Some of these toxins include arsenic, carbon monoxide, and lead. When directly consumed, these chemicals are very pernicious, so it is obvious that they can cause diseases like ...
Lung cancer dates back to 1761 when it was called disease. In 1878 only 1% of the populations were thought to have it. When the 1900s came by that number rose to 15%. There was only 374 case filed by 1912. It wasn’t until 1929 when smoking became a factor in lung cancer. Fritz Lickint was the first person to tell the public about the dangers of smoking that which went into a campaign act to tell worldwide about the dangers of smoking.
Smoking cigarettes is a detrimental practice not only to the smoker, but also to everyone around the smoker. According to an article from the American Lung Association, “Health Effects” (n.d.), “Smoking is the leading cause of preventable death in the U.S., causing over 438,000 deaths per year”. The umbrella term for tobacco use includes the use of cigarettes, cigars, e-cigs and chewing tobacco. While tobacco causes adverse health consequences, it also has been a unifying factor for change in public health. While the tobacco industries targets specific populations, public health specifically targets smokers, possible smokers, and the public to influence cessation, policies and education.
There are over 7,000 chemicals present in tobacco smoke. Of those over 250 are deemed harmful, and of those 69 are cancer causing. Those cancer causing substances are called carcinogens (Nugel). It is clear that cancer and smoking can be linked. Smoking causes cancer of the lung esophagus, larynx, mouth,...
...el and formation of thrombi. Over 7000 chemicals found in tobacco smoke cause breathing difficulty, wheezing, lung infections and chest pain. The long-term effects of smoking can cause many cancers as it contains many carcinogens. It is the leading cause of cancer affecting the lungs, mouth, throat, kidney, stomach and many other areas. Not only do tobacco products affect the user, but also the ones around them. Second-hand smoke can increase lung cancer, heart and breathing problems, as well as a premature death. In pregnant women, the unborn baby may be subject to health problems. By eliminating tobacco products, not only do previous smokers reduce the risk of developing cancer, but also can reduce their chance of dying prematurely by a very large percentage. For example, quitting at the age of 30 can reduce their chance of dying prematurely by over 90 percent.
This represents 4.0% of all male 1.8% of female hospitalisations respectively. The epidemiologic evidence and the corresponding biological understanding of respiratory cancer have supported the conclusion that smoking causes lung cancer. It is well documented that cigarette smoke: · is the major cause of lung cancer (primary carcinoma of the lung). · is a cause of heart disease, chronic lung disease, and oesophageal cancer.
Smoking is a simple process of inhaling and exhaling the fumes of burning tobacco, but it has deadly consequences. According to the American Cancer Society, smoking is the most preventable cause of death in America today (Encarta, 2002). Until the 1940?s, smoking was considered harmless. It was at this time that epidemiologists noticed a dramatic increase in the cases of lung cancer. A study was then conducted between smokers and nonsmokers to determine if cigarettes were the cause of this increase. This study, conducted by the American Cancer Society, found increased mortality among smokers. Yet it was not until 1964 that the Surgeon General put out a report acknowledging the danger of cigarettes. The first action to curb smoking was the mandate of a warning on cigarette packages by the Federal Trade Commission (Encarta, 2002). In 1971, all cigarette advertising was banned from radio and television, and cities and states passed laws requiring nonsmoking sections in public places and workplaces (Encarta, 2002). Now in some cities smoking is being completely banned from public places and workplaces and various people are striving for more of these laws against smoking.
Scientists and health officials have been arguing the detrimental effects smoking has on our health for many years. Smoking can lead to serious complications including asthma, pancreas, lung and stomach cancer due to the large number of carcinogens (cancer causing chemicals) and other various substances added to it. It is a health hazard for both smokers and non-smokers and it is especially harmful to unborn babies. Although smokers claim that it helps them to relax and release stress, the negative aspects of the habit take over the positive. As it has been stressed by the scientists and experts, there are some very severe reasons of smoking but its crucial consequences should also be taken into consideration.
