According to World Health Organization, every year there are about 11,000 people die due to smoking. It means that every 10 seconds there is 1 person in dead. Long time ago, people discovered the nicotine in tobacco is addictive component, which is the cause of cancers in people who smoke, such as lung, bladder, pancreas, kidney, mouth, esophagus, larynx (best smoker). Chemicals in tobacco is carcinogenic agents through the following mechanisms: They create genetic alterations that stimulate the formation and development of tumors, and devastate natural ability of the body, which are to destroy the cells carrying the genetic lesion. While normal cells grow old or get hurt-a special program activated to make the order for cells to stop dividing and will die soon. However, nicotine delete this protection mechanism and presses them to continue living.
Nicotine can survive long in the lungs and blood, so the cells that are vulnerable to carcinogens will increasingly live longer, which increases the risk of cancer.
- The harmful effects of tobacco:
Cigarettes contain over 4,000 chemicals, mostly toxic substances in which there are 43 cancer causing agents. Nicotine is a toxic substance having high amount in tobacco: “A drop of nicotine can kill a rabbit and seven grams of nicotine kills a horse”.
What you start smoking is to gradually make you rely on nicotine (like heroin, it make users drug and find difficultly to quit. When smoke resin in cigarette, smoke clings to the lungs. If you smoke ten cigarettes once day, smokers inhale into body 105 grams of plastic per year. Cigarette smoking increases the chance of developing many serious diseases. People who smoke will die sooner than those who do not smoke, not one day, one month, one year, but for many years later.
- Smoking having a filter is safe?
Statistics have showed that the rate of use of filtered cigarettes also increase the rick of lung cancer. Until now, so many people have believed that the filter may filter out the toxins of tobacco, but according to scientists said that the appearance of the filter on the year 1950 have led to an increase in lung cancer cases, so they have put a question on the cigarette filters.
There is an association between the use of tobacco filter with lung cancer. The filter makes the smoke inhaled the slightly deeper and longer because toxins enter the body increasingly.
- CO in tobacco effects on the body
CO is a poisonous gas produced from the combustion of organic substances like tobacco, which is one of the hazardous substances contained in tobacco smoke are harmful to the heart, lungs and blood vessels. In pregnant women, CO enters the bloodstream through the fetus as the oxygen supply is reduced. CO present in air pollution caused by burning waste oil in urban. People who do not smoke, but breathe polluted air, they also have CO in the blood.
When inhaling the smoke into the lungs, CO pass into the lung, blood and attack hemoglobin-a substance in red blood cells carrying oxygen throughout the body. Red blood cells are so sensitive to Co than oxygen, so CO in the blood will attack and replace oxygen in the body. As a result, the heart must work harder to meet the body’s demand for oxygen. Heart has to work more, and the less oxygen supply to the heart as well as the effects of cigarette smoke to the heart and blood vessels such as coronary arteries that feed the heart easily lead to myocardial infarction, stroke, lung cancer.
- Smoking causes heart disease:
Tobacco is the main cause, or an independent risk for cardiovascular disease. Smoke effects on the process of atherosclerosis:
– Hurt intravascular: endothelial cell layer is compromised, it is no longer smooth and is a condition of formation of plaque inside the intravascular.
– Making lipid metabolism blood: lead to decrease HDL cholesterol (lipids are beneficial for the body).
– Increase LDL cholesterol: increase triglycerides- a harmful lipids, and increase the likelihood of clot formation resulting in causing myocardial infarction or stroke.
– Increase levels of catecholamines in the blood: CO will be increasing as noted above and the onset of angina or myocardial infarction.
On the other hand, it can increase in blood nicotine that causes vasoconstriction, blood pressure, heart rate, cardiac overload activity (more heart activities can cause cardiac arrhythmias, sometimes can affect the lives of people smoking.
Benefits of quitting:
Quitting smoking will improve the said diseases, especially cardiovascular diseases.
Tobacco cessation after one year, risk of death from coronary heart disease can be reduced by 50%. And you can quit smoke 10-year mortality from coronary, heart disease drop to 70% and if more than 10 years, the mortality rate of people smoking likes that of non-smoke ones.
With practical benefits above, we do not quit smoking and discard the notion. No smoking help us last the live longer and healthier, less disease and reduce the risk of heart disease, cancer … and save some money.
To quit you need to:
– Must have the will of overcoming yourself
– Clearly define the time of implementation
– Quit immediately, no step by step
– Avoid places that evoke the urge to smoke
– Some if finding cravings, must be determined to expire over time
