Among all metabolic cancer susceptibility genes, the association of GSTM1 deficiency with cancer risk is the most consistent and unidirectional. Various experimental and epidemiological observations support the role of this gene in tobacco-related cancers. For example, it has been observed that the excretion of urinary mutagens and the number of lung tissue DNA adducts in GSTM1-deficient smokers is significantly greater than those carrying the wild-type allele 55 — Various epidemiological studies also support the premise that deficiency of this enzyme predisposes for lung and bladder cancers Furthermore, low activity alleles of GSTPi have been often found in association with different types of human cancers 59 , In addition to anomalies of biotransformation enzyme genes, inactivation of tumour suppressor genes such as p53 , and activation of the proto-oncogene K-ras are also involved in tobacco-related cancers.
Various mutated forms of tumour suppressor gene p53 have been commonly detected in lung tumours and it has been found that these mutations are predominantly located in exons 5 to 8. The nature of point mutations in this gene has been extensively investigated and studies show that the most common mutant allele of the p53 gene possesses a G: C transversion 61 , which is associated with tobacco use 62 , The above studies show that several genetically controlled polymorphic enzymes and enzyme systems are linked to tobacco carcinogen activation and deactivation.
Some of these genes have been identified and characterized, but others remain undiscovered. Not only the independent effects of single gene polymorphisms, but an interplay of multiple gene interactions appear to be involved.
The complexity of epidemiological studies, which have many uncontrollable variables, makes it difficult to study such interactions and their control in human studies. Additionally, many of the enzymes involved in tobacco carcinogen metabolism are also induced by other environmental factors such as alcohol use, dietary constituents, pesticide and xenobiotic exposure, hormonal status, etc, further complicating the interpretation of data.
The interaction of many of these genes with each other and the effect of environmental factors are just beginning to be examined.
The adverse effects of cigarette smoke on human health are widely recognized. It is the main etiological agent in chronic obstructive pulmonary disease and lung cancer, and is a known human carcinogen. While the risks to human health from active smoking are accepted, evidence supporting the risk of involuntary exposure to environmental tobacco smoke ETS has accumulated in recent years.
It is the main source of toxicant exposure by inhalation in nonsmokers. Despite recent regulations, smoking in public enterprises is not uncommon.
However, despite an occasional report on the effect of secondhand smoke in nonsmokers, little attention was given to this aspect of smoking until about ETS is now regarded as a risk factor for development of lung cancer, cardiovascular disease and altered lung functions in passive smokers In general, children exposed to ETS show deterioration of lung function, more days of restricted activity, more pulmonary infections, more days in bed, more absences from school and more hospitalization than children living in nonsmoking homes Passive smoking is also implicated in increasing atherosclerosis in individuals 15 to 65 years of age.
Children exposed to ETS are at higher risk of developing cardiovascular disorders. Quantitative risk estimates were obtained by measuring the intimal-medial thickness of the carotid artery in a large longitudinal atherosclerosis risk study of 10, individuals.
A recent meta-analysis 67 of 18 epidemiological studies 10 cohort and eight case-control further showed an increased RR of CAD in ETS-exposed individuals. These investigators also identified a significant dose-response relationship between the intensity of smoke exposure and risk of CAD in passive smokers. Cardiovascular health risks of smoke-exposed women are of particular concern.
Although the exposure to ETS is a current topic of debate in tobacco-related cancers and other lung diseases, the limited research at the basic experimental level provides a strong argument for launching experimental studies to support human data and explore disease mechanisms.
Follow-up of news stories, and local and state ordinances, leads to the conclusion that more communities and states are restricting exposure to secondhand smoke. The results are summarized below. A total of hits were obtained and a careful review of the abstracts provided the following distribution:. A similar search of the NIH database from to revealed grants in all award categories.
The grant distribution by category was as follows:. All the remaining grants generally supported behavioural and epidemiological studies in humans or other systems. Thus, it is clear that the need for basic experimental research in the field of smoking-associated diseases and the mechanisms through which tobacco smoke causes various diseases remain as important as they ever were.
The escalation of health care costs makes it even more necessary to find ways to protect the health of smokers and smoke-exposed individuals with any dietary or therapeutic interventions that hold promise. The most benefit is likely to result from detailed epidemiological studies complemented by specific molecular genotyping of various populations. Ideally, studies of this type will re-evaluate the prevalence of smoking and tobacco use and determine the exact nature of tobacco-related disease incidence, the role of contributory factors such as dietary habits, exposure to other substances and the genetic composition of subpopulations most at risk.
Various biochemical and molecular assays will need to be applied to screen nonsmoker and smoker populations for a variety of health risks. Analysis of the results from such studies will help identify the main interacting factors for various health risks and define relationships among various epidemiological parameters.
It would appear necessary to assemble teams of multidisciplinary investigators to perform these coordinated human studies in the field and in the laboratory. By nature, such studies are expensive and will involve commitment of resources, time and substantial amounts of funds to obtain meaningful results.
Given the limited resources and competing priorities for research funding, it is not easy to undertake such human studies. Hence, the experimental studies in animal models using inhalation exposure to whole smoke, and not individual constituents of smoke, is probably the next best approach for smoking and health programs.
The human epidemiological studies described in the present review have identified a number of genes that appear to have a distinct role in various tobacco-related diseases, and cancers in particular. Inability to control all the different variables in human studies has made it difficult to clearly define the contribution of various suspect genes in tobacco carcinogenesis. With the recent commercial availability of a variety of transgenic and knock-out animals for research, it would be most desirable, as a first step, to use these animals to establish experimental models of various tobacco-related diseases which can then be used for determining the contribution of different genes to disease processes and for elucidation of the mechanism s of disease development.
Furthermore, these animal models can be used to identify various agents possessing protective and therapeutic potential. Research efforts in the area of smoking and health would benefit by focusing on studies of the in vivo effects of inhaled whole cigarette smoke in animal models of known specific genetic composition.
Selection of the genetic composition would also require a thorough consideration of the information available from human molecular epidemiological studies. As indicated earlier, there are a number of genes that clearly influence the development of smoke-related diseases. In this context, many relevant transgenic and knock-out animals that can be effectively used for the study of tobacco-related diseases are now becoming available.

Smoking was consideredharmless until about 50 years ago. The American Tobacco Company disagrees with this.
Research since then has proven much about this American pastime. The American Tobacco Company r The Dangers of Smoking When Christopher Columbus discovered the Americas, he found the natives using tobacco in much the same manner as it is used today.
The American Indians believed it to possess 0medicinal properties, which was the main reason for its introduction into Europe. Tobacco was important in Indian ceremonies, such as the smoking of the pipe of peace. There are many things today which cause us harm.
One can spend virtually an entire day listing the hazards faced by modern society. However, none of these hazards are as deadly as a habit millions of American's bring on themselves twenty to thirty times a day.
Smoking is the cause of a multitude of medical problems that plague not only the individual smoker, but everyone else as well. Comparative forms of tobacco use In native Indians were smoking rolled up tobacco leaves.
In the 16th century tobacco smoking spread to Europe. By the late tobacco tolled in paper called cigarettes were a major industry with billions being sold each year.
Today there are many products that contain tobacco. Cigarettes and snuff are the most popular on the market. Cigarette smoking has been proven to be hazardous to your health. It wasn t until that the actual truth came out about cigarette use.
From the years Kent brand cigarettes was allowed to use a filter containing asbestos. Cigarette ads were allowed on televi Secondhand Smoke, Is It a Hazard? By the time people actually decided to take care of their health and finally saw how life-threatening smoking Lung cancer is an uncontrolled, extremely deadly division of cells in the lung World Book, Lung Cancer. The two major types of lung cancer include small and non-small cell. Many different risk factors contribute to lung cancer.
There are numerous symptoms that are difficult to detect in the early stages of lung cancer. Doctors use special machines to detect the severity of each stage. After the Environmental Protection Agency and the Surgeon General stated that cigarettes cause lung cancer there was a tremendous movement to make cigarettes illegal. Now the debate is on environmental to SmokingSmoking is the inhalation and exhalation of the fumes of burning tobacco. The dried leaves of the plant are smoked in a pipe or in cigar form, but mostly in cigarettes.
About 50 million Americans currently smoke a total of billion cigarettes each year. At first smoking was considerd harmless, but labortaory and clinical res Tobacco Should Be Illegal! Why isn t tobacco considered a drug?
When the facts are reviewed, tobacco produces all of the effects of a drug although isn t recognized as one. What makes tobacco different from any other drug? Among the many effects of tobacco on the body, includes the ability to be addictive and cause numerous cases of cancer. Unfortunately, tobacco is not recognized Lung Cancer Cancer is a disease marked by uncontrolled growth of abnormal cells.
The abnormal cells may no longer do the work of normal cells and in turn crowd out and destroy the healthy tissue. Most of the victims of cancer die from lung cancer.
Many of these cases could have been avoided because it most often occurs in people over the age of 50 with a history of smoking. There are different t Peer Pressures of High School Glaring down at the reddish glow coming from the tip of the cigarette, I found out that I was in a peer pressure situation. Peer Pressure can be a huge problem for some young adults. Smoking is just one of the peer pressures someone can go through. Alcohol and staying out l Smoking is the most important single preventable cause of illness and premature death in North America.
In the United States alone, more than , deaths are attributed to tobacco use each year. This exceeds the total number of American lives lost in all of the wars fought since the country was founded. In the Royal College of Physicians of London had released a significant study, wh While eating dinner at El Ranchito an acrid plume of smoke wafts over my table causing my eyes to water and my nose to become congested.
Once again another inconsiderate smoker has ruined a nice meal. Second-hand smoke is both a danger and a discomfort to non-smokers, and should be banned in I do not smoke for many reasons.
One is because I am active in my community as a good student, as a community leader, and as a dedicated worker. I have to be a good role model to those in the community and smoking is not one of those aspects to be looked up to.
Another reason I do not smoke is because I have been personally affected by the negative impact of smoking. Smoking on School Grounds By Thomas John Marigliano Our high school administrative board has been trying to decide weather smoking on school grounds should be restricted. New York State regulates smoking in all public places except for schools. We have been educating students for many years about the dangers of smoking, so why do we still allow students to smoke on school grounds.
Should You Use Tobacco? There are about 1. Many historians believe smoking started with the Native Americans. There are many uses of the tobacco leaf. Also there are many things to consider if you thinking about using any type of tobacco. First, one must realize there is illness associated with the use of tobacco. The hardest thing I've ever had to deal with was seeing my father, of almost seventeen years, cry. That was the day my grandfather died, the day i understood everything.

I Disgusting Smoke Stains and Odors Has anyone ever walked by you with the smell of stagnant smoke on his or her clothes, or have you ever met someone that has yellow stains on their teeth from nicotine? Smoking cigarettes not only makes people smell bad, but the things around them as well. The appearance of a smoker and their belongings is disgusting and Smoking is an addiction. When a person smokes a tobacco product, they inhale the smoke, which contains nicotine as well as over other chemicals.
A cigarette contains cover paper, tobacco, nicotine, filter, and tar. The tobacco is where the tar comes from in a cigarette.
The other substances that are in the cigarette produce this tar. The tar causes problems with the throat, mouth, and Every time one takes a puff of a cigarette they re playing a dangerous game with life. I always wondered, Why are cigarettes so deadly, what is in cigarettes, if people know they re deadly then why do they still smoke them, and finally why does the government allow people to buy these when they can kill you?
November 15, Protecting Non-Smokers on Campus People have many different views about smoking in public places. Smokers feel it is their right to smoke where and when they want. But non-smokers like me, feel that people who smoke are actually endangering my life and the lives of non-smokers. Smoking causes heart disease, lung cancer and other respiratory diseases.
If you are a smoker you should pay close attention, but even if you are not a smoker perhaps this will prevent you from smoking or guide you in helping someone else quit smoking Preview: Tobacco is used all over the world for centuries.

There are multiple factors that have contributed to the surge of teenage smokers, and several suggestions have been made to suppress it.
Smoking is harmful to a smoker s health as well as the people around the smoker. The first and second hand smoke can cause lung disease, such as emphysema and lung cancer. It can also cause cancer of the mouth and throat. A smoker s hands, breath, clothes, car, and house smell like cigarette smoke.
They also have yellow teeth. That s why quitting is so important. Quitting is not easy, bu Cigarette Smoking For a long time now many people have different views about smoking in public places. On the other hand non-smokers feel smokers violate their rights and endanger there life. Smoking causes heart disease, lung cancer and other serious illnesses.
Cigarette smoking is the number one cause of lung cancer Steps to a Better Life The decision to quit smoking is one decision a person will never regret! Smoking causes around , deaths each year, just in the United States. Quitting smoking cuts the risk of lung cancer, many other cancers, heart disease, stroke, other lung diseases, and other respiratory illnesses.
Quitting smoking, while pregnant, also increases the chances of survival The primary goal of my behavior change project is not to quit smoking, but to cut back on the amount of cigarettes that I smoke per day. Since I enjoy smoking after I eat, I plan to allow myself a cigarette after each meal, after that I am allowing myself three other cigarettes per day.
This will total six cigarettes per day, which may seem like a lot to some people, but this is a dramatic cut
This paper seeks to investigate both the benefits and side effects of smoking in public and finally argue a case for or against the ban on smoking in public places. Proponents of the ban of smoking in public places argue that because not everyone is a smoker, the smell of cigarette smoke is offensive to non-smokers.
