Cigarette Smoking and the body
Tobacco is consumed worldwide everyday by millions of people. Many people cannot prevent themselves from smoking because tobacco contains a drug called nicotine that makes them feel as if they need it in order to function normally. Nicotine is a substance found in tobacco. It is found in all tobacco products such as: cigarettes, pipe tobacco, chewing tobacco, and cigars. When a person smokes a tobacco product, they inhale the smoke, which contains nicotine as well as over 500 chemicals, including formaldehyde (used to preserve dead bodies), cyanide, insecticide, carbon monoxide and tar [1]. I personally think that smoking is detrimental and that it has many fatal side effects, but eventhough many people know of these effects, they still chose to smoke. For what reason? Nicotine has a few positive effects on the body. It stimulates memory and alertness, enhancing cognitive skills that require speed, reaction time, vigilance, and work performance. It acts as a mood-altering agent, it tends to alleviate boredom and reduce stress, and reduces aggressive responses to stressful events. It also tends to be an appetite suppressant, specifically decreasing the appetite for simple carbohydrates (sweets)
Once these treatments are tested to be effective and safe, a person suffering from lung cancer can be less dubious about being treated and hence the deaths caused by lung cancer would decrease. Remember It only takes 3 cigarettes for a teenager to get hooked. [2] The heart and circulatory system are greatly affected by cigarette smoking over a long term. After eight hours, nicotine and carbon monoxide levels in a person's blood are reduced by half; oxygen levels return to normal, and your heart and lungs will begin to repair the damage caused by cigarette smoke. [1] Tar contains carcinogens which causes changes in DNA in bronchial epithelial cells, leading to the development of a bronchial carcinoma. The common side effects of chemotherapy include gastrointestinal symptoms (vomiting, nausea, etc), anaemia, infection (white blood cell production may decrease), mucositis, fatigue, alopecia (hair loss) and depression. After only twenty minutes of quitting a person's blood pressure and pulse rate returns to normal. People who use tobacco products frequently depend upon it providing these side effects to help them accomplish certain tasks at specific levels of performance. [4]Women who smoke have a greater risk of premature detachment of the placenta. This increases cholesterol and clogging of arteries which, in turn, will lead to poor circulation to the extremities of the body and high blood pressure and a higher heart rate. These include Photodynamic Therapy, Immunotherapy, Gene therapy, Cytokines, Interferons, Onconase and L-NDDP. Oncologists cannot treat only cancer cells with this technique so many other cells are also eliminated. [7] There may be a few benefits to smoking but the dangers are undoubtedly greater and it is in the interest of any smoker, who desires a long healthy life, to quit smoking immediately. Once detachment has occurred, prenatal death rates also increase. The circulatory system may be repaired with surgery but if a person's circulatory system is so far gone, it is only a matter of time before they die.
