How much physical damage does an average cigarette do to your body?
Q: I would like to stress the idea of "physically". I understand the nicotine addiction and the mental addiction. What I am curious about is how much tar, and other harmful substances is in a single cigarette. I know that this may vary between menthol, clove, regular, light, etc. I'm also aware of the human body's amazing ability to heal it self. I would like to know what chemicals stick with you from said cigarette. Also, if your body eventually removes those chemicals from itself. Thanks.
A: Most of the tar from a cigarette is broken down and absorbed, but some stays. This tar irritates the delicate microscopic compartments, causing them to merge into bigger ones. This means less surface area to absorb oxygen. Over time, this recurring reaction makes it very dificult to breath. Another thing that cigarettes do to your body has to do with the nicotine. Your throat and lungs are lined with microscopic hairs called cilia. These push mucus full of particles that you breath in up to the throat to be swallowed and digested. Nicotine paralyizes these cilia. However, with extended exposure, this parylization can actually deactivate these cilia, effectively killing them. This means mucus can't be transported up through the lungs to the throat, and the person has to cough to clear it. This is what causes that deep phlegmy cough that all smokers eventually get.
Please help me find a title!?!?
Q: ____________ :The hazards of smokingThis is the essay. Warning everything on here is not real. It's a "Fake Essay"“Smoking is a very hazardous habit. It is actually the most dangerous legal consumer product on the face of this planet.” Dr. Melbourne Fox, Director of American Lung Association (Melbourne 25).In this generation, smokers are everywhere: on TV, movies, and even just walking down the street. Famous, young people smoke and it encourages other younger people to do. Smoking ages range from pre-teens to the elderly. What many people don’t know that that even though it may be cool and hip, it can cause serious problems for them. Smoking is well known to cause many unhealthy habits in people’s lives and even affect peoples’ mental and physical health. Smoking can cause serious health issues. It hurts people besides the smoker. Also, it can cause addiction. Although many smokers claim that smoking helps them, there are many more cons that out-weigh the pros.Smoking can cause lots of different health problems. In the book, Health Effects of Smoking, by Dr. Carey Melbourne, writes, “Smoking harms nearly every organ of the body, causing many diseases” (Melbourne 5). Smoking hurts the body, so in general, it deteriorates the smoker’s health. As a result, the smoker ends up with diseases. Dr. William deGraffenried, a researcher, writes about this in his article, “Why Smoke?” He writes, “Smoking causes cancers of the bladders, pharynx, larynx, and lungs. It also causes serious heart and respiratory diseases” (deGraffenried 9). Studies show that people that had smoked or are smoking, had at least one chronic disease. These diseases can be very harmful to the human body and can even result in death. Now that we know what smoking can do to a smoker’s body, let’s see what it can do to others. Secondhand smoke can be harmful in its own way. It is very dangerous to expose anybody to secondhand smoke. Melbourne writes, “The more secondhand smoke humans are exposed to, the higher the level of these harmful chemicals in your body” (Melbourne 12). Even if a non-smoker does not smoke, just being around smoke can be hazardous to ones’ health. Parents have to be on watch when they smoke. Any type of exposure to their children can be harmful. DeGraffenried writes, “Secondhand smoke is responsible for 20,000 to 1 million children for having asthma attacks and 150,000 to 300,000 infants that are younger than 18 months of age to have lung infection (such as pneumonia and bronchitis)” (deGraffenried 15). Pregnant woman should also be aware of what is around them. Any type of smoke can cause their babies to have low birth weight or can even cause SIDS (Sudden Infant Death Syndrome). Secondhand smoke is really serious and the effects are preposterous. Nonsmokers should be aware and try to avoid it. We should now take a look at another bad habit of smoking, addiction.Addiction is the state of being enslaved to a habit or practice or to something that is psychologically or physically habit-forming. This state is as much a threat as anything. Nicotine is found in substantial amounts in all forms of tobacco. Nicotine is a substance that can become addicting for the human body. Once inhaled it reaches the brain within seconds. Melbourne writes about the effect: “ As the nicotine level drops in the blood, smokers feel edgy and agitated--the start of nicotine withdrawal. So in order to relieve the discomforts, the smoker light up another cigarette…then another…and another” (Melbourne 3). As a result the smokers wants more to satisfy their need and end up becoming addicted to it. Melbourne writes, “Although 70% of smokers want to quit and more than 40% try to quit each year, fewer than 5% succeed” (Melbourne 6). This happens because smokers are not only physically addicted to it, they are emotionally linked to it. This trait makes it harder for smokers to break the habit.Even with all the awful things that smoking can do to our bodies, there are still people that think the opposite. Smokers claim that smoking is not bad for them at all, on the contrary it is good for them. Smoker, Gabriella Dominguez, states,” By smoking I feel relief from all the stress that I have. It helps me relax and lets me focus more.” Dr. Lana Cain, on her website Benefitsofsmoking.com writes, “Smoking burns up an extra 300 calories each day. This method is really good and to stop using it would cause a huge gain of obese people in America”. But is it really worth the risk of getting a fatal disease? While this may be true for the smoker, nonsmokers have different views. The risk of getting sick or hurting others may be more important than relaxing or losing weight..With so many sickness caused by smoking, the risk of hurting others, and the risk of addiction, it is easy to see why many people do not smoke. Also the ability to cause cancer, low birth weight, and the way smokers depend on it is not a very attractable impression either.

How did I lose this debate?
Q: Recently we had to debate about if tobacco prices should go up or not. I was for the prices rising, and my argument was because it s a dangerous substance and that such substances should not be distributed at a low price and raising it would discourage buying it. I spoke about nicotine, effects smoking has on the human body and babies as well as that smoking in itself produces poisonous gases. Now my opponent simply said "Well, then should we raise the price on eveything bad for you like fast food or soda?" I argued that soda and fast food were not nearly as serious, pointing out some of the side effects associated with tobacco use and recommended she give a reason why the prices should not rise. She never did, only saying we should raise the prices on everything else that could be considered harmful if we raise the price of tobacco. Now, the debate was judged by our peers, students our age. I suspect bias, as I can never win when they judge but am able to at other times. Help?Keep in mind, if you think I lost fairly then explain why. I want to improve but feel this one was not fair.
A: I don't know about bias, but obviously her argument was more persuasive to your peers. I agree with you, however.The "slippery slope" argument (i.e. where will it lead?) can be refuted. It is possible to calculate risk, and it makes sense to tax the most risky things, especially when they affect society as a whole. Smoking is the number one cause of preventable illness and death - to the smoker and other people. That is a statistical fact. Sure, sugar can have detrimental effect, but so can running with scissors. And all that can be mathematically determined. The only issue should be where on the scale do we begin taxing risk.
