Cigarette Smoking Leads To Diseases
Cigarette smokers are encountered with the difficulty of quitting this habit. This disadvantageous effect happens as a result of the secretion of large amounts of cholinergic receptors in the brain. This will result in the stimulation of dopamine that gives pleasure to the cigarette smoker. So, the best approach required to be followed by any cigarette smoker would be to gradually cut back on the number of cigarettes he smokes in a given time span. In addition to the other effects of nicotine, one may also experience a fast heart rate induced by nicotine every time a tobacco cigarette is smoked. From the medical point of view, a constant flux in heart rates is not at all good. A greater frequency in this matter related to the heart rate induced by drugs such as nicotine can lead to heart diseases, a report by World Health Organisation says.
According to the organization, tobacco is the main cause of diseases affecting the heart and lungs. This includes diseases and conditions like heart attacks, chronic obstructive pulmonary disease, strokes, emphysema and cancers of different organs. Some of the cancers induced by tobacco cigarette smoking are lung cancer, cancers of the larynx & mouth, and also the pancreas. Cigarette smoke will lead one to be afflicted with myocardial infractions, peripheral vascular disease and hyper tension. According to World Health Organization estimates, tobacco was the primary factor responsible for over 6 million deaths in 2004 and about 120 million deaths in the 20th century alone.The smoke from cigarette contains a massive amount of cancer-causing agents; this is in addition to nicotine’s addictive effects on the human’s central nervous system. They make this happen by binding themselves to DNA and in the process cause many hazardous genetic mutations. Nicotine is found to be the main culprit that is responsible for binding DNA thereby causing genetic mutations which, in turn, leads to cancer.
According to scientists, nicotine is found to disrupt the natural processes of programmed cell death, otherwise called apoptosis. The defective cells consist of waste DNA and other useless materials. When apoptosis is not made to happen in the normal way, natural cell death does not take place. Instead, the defective cells are permitted to proliferate and grow large in an uncontrollable fashion. This is what happens when cancer occurs and is the main reason behind cigarette smokers getting more prone to developing different types of cancers. When apoptosis is taking place uncontrollably, thanks to the dangerous chemicals such as nicotine, it will kill off the normal cells. This might be the process that happens in the heart tissues of hard core cigarette smokers who are suffering from heart diseases. Cigarette smokers often complain of excessive numbness of their fingers, arms, toes and legs as a result of a decrease in blood circulation. There are no scientific studies to hold up an exact explanation for this. But, based on the knowledge so far received and the rate of increase in the death of cigarette smokers, this hypothetical explanation assumes some degree of credence.
