The Paper

...Bryce Wawrzyniak February 19, 2012 Eng-106 Prof. Eleanor Smoking Smoking has been the center of many health studies and controversy around the world. There are many reason people smoke, but the one thing every smoker has in common is that they are becoming less healthy with every cigarette that they consume. These health issues are a direct cause of the cigarettes and the toxins that are incased in a small piece of paper. How can such a small 3-inch item contain so many harmful elements that can be so detrimental to the body? Also, why do so many people insist on continuing to smoke even though they know the side affects and how it can deteriorate your body? As many research studies have shown smoking has a direct correlation to lung disease. With smoking, there are many other problems such as; lack of breathes, rotten teeth, coughing spells, smelly odor and others. With all of these problems that stem from smoking, why would anyone continue to smoke? Starting with the first problem, lung disease. The toxins that are inside of the cigarette are the cause of the lung disease. Of these toxins include tar, butane, formaldehyde, arsenic, and many other terrible ingredients (Breyer, 2011). So every time you smoke a single cigarette you are ingesting dead body preservative, lighter fluid, and poison. There is no reason to smoke and put these harmful products into your body. Cigarettes will change your life and not for the better. Cigarettes not only cause health issues but...

Smoking

...The Effects of Cigarette Smoking No Smoking SignThere have been numerous campaigns against cigarette smoking communicating that this vice causes death. But a threat to health doesn’t seem to be a good reason for quitting anymore. People somehow block themselves and ignore all the information that is given to them. The purpose of this essay is to discuss three effects of cigarette smoking, besides the broadly mentioned possibility of developing cancer or dying, which are the smell of smoke, the stained teeth, and the cost of doing it. The first effect of cigarette smoking, and probably the one that the non-smokers hate the most, is that it permeates everything around it. Smokers usually have smelly hair, breath, clothes, and, if they smoke indoors, a smelly room. The stench of cigarette smoke is very penetrating and hard to remove. Even if the person quits smoking the odor remains for a long time. The second effect of cigarette smoking is one that most people don’t even take into consideration. It stains the teeth yellow or sometimes even brown. Since this effect is long term, most people are not aware of it when they begin smoking. The truth is that a cigarette stain is very hard to eliminate from the teeth, and it will probably end up costing a considerable amount of money. Yellow teeth are disgusting because they give an unhygienic image and make people look older. The third effect of smoking is that it will eventually end up affecting the smoker’s personal economy...

As serious as this notion of facing grave illness or death seems, that has not seemed to be an adequate reason to quit still. People for whatever the reasons seem to have the ability to insulate themselves from the obvious facts that are shown to them. This essay intends to offer some other effects of cigarette smoking apart from the obvious developing of cancer or death. There are easier reasons such as the cost of smoking, the actual smell of smoke and stained teeth. As the spouse of a lifelong smoker the effect of these is far too true for them not to be mentioned. The smell of smoke is the thing that probably affects non-smokers the worst. Smoke has a tendency to get into everything around it. As the smoker carries out their habit indoors, the results include a constantly smelly room. It usually takes days for the scent to go away with the individual not present in there. Every type of clothing seems to have been penetrated by a smoke smell, and no matter what is used, the smell is difficult to be removed. Even the walls can seem to turn color with the long term effects of indoor smoking. Another effect of smoking and one that many people are not aware of is the damage to teeth. Dental hygiene is highly affected especially if there is chronic smoking. Cigarette stains can...

It is currently the leading cause of death in our country, due to its harmful and addicting contents, such as nicotine and tobacco.

Pot : Calling the Kettle Black

...illnesses have wretched side effects such as nausea, depression, and loss of appetite – these severe side effects are forcing many patients to make the choice to refuse current treatment methods or medications that would otherwise extend or save their lives. Recent discoveries have shown that using marijuana as form of treatment for chronic illnesses such as HIV/AIDs, cancer, fibromyalgia, and multiple sclerosis, has shown to have justifiable healing and sedative reprieve without otherwise having to suffer the nasty side effects that other treatments have to offer. Current legalization forces patients with chronic and life-threatening illness to either suffer horrendous medicinal side effects from treatment and illness, or break the law by self-medicating by way of marijuana. Medical marijuana should be legalized for the chronically ill as an alternative treatment method to painful and horrid side effects of current treatment methods that are in place. Marijuana originates from the dried parts of the Cannabis Sativa or hemp plant and is known by hundreds of street names such as pot, weed, and grass. The hemp plant has existed for thousands of years with archaeologists discovering hemp fibers that date back as far as 400 BCE (Henningfield, 2008).

I have a bad smoking habit, in which I developed while I was incarcerated. I always told myself that I would never pick up this terrible habit when I was a teenager, more importantly I didn’t pick up smoking until I was 18. There were role models for my smoking habit, such as the lady prisoners who smoke on a daily basis. They had told me “try it, it will calm your nerves down”, granted that it would calm my nerves down, I tried it.

A sensation I been chasing years later, that I am aware of I will never receive again. Why do I continue? That is a million dollar question.

Social Media Effects On Electronic Cigarettes

...The benefits are numerous, they can range from decreased risk of cardiovascular disease to simply decreasing the cravings to smoke (Nowak et al., 2014). Cigarettes are associated with high costs not only to the smoker’s health but to their budget as well. Groups associated with smoking are people who have access to the product, so they can purchase themselves, through a friend or through a family member. Either way the product costs money and therefore a majority of smokers are middle class (Harrell et al., 2015). Men are more likely than women to smoke and people with mental health conditions are more likely than people without mental health conditions to smoke (Cummins et al., 2014). Other factors associated with the likelihood of one smoking are impulsivity and sensation-seeking. The more impulsive and/or sensation seeking a person is the greater the chance they are at using cigarettes. Making it challenging to help these people switch from conventional cigarettes to electronic cigarettes for two reasons. One since e-cigarettes look similar to tobacco cigarettes and hold almost all similarities in every way. It is easier for an impulsive smoker to adjust because they can bring out the electronic cigarette and use it as any other cigarettes without...
