There are approximately 4000 chemicals found in tobacco smoke, and of all those, nicotine is by far the most harmful. Nicotine weakens the eyesight, influences the nervous system, is harmful for the heart and blood circulation, and affects the liver, stomach, and sexual glands. Many smokers do not realise that nicotine is one of the most dangerous nerve gases. Its effects are as poisonous as the effects of cyanide. In farming, nicotine is used as an insecticide. Nicotine is carried in the blood and its effects can be seen rapidly after smoking just one cigarette. The temperature of the skin lowers by 5%C and the heart beats faster. The symptoms of acute nicotine poisoning are; headaches, vertigo, shaky hands, coughing up mucus, and general weakness. Chronic nicotine poisoning in heavy smokers causes poor appetite, digestive problems, stomach ulcers, menstrual problems, spontaneous abortion, impotence, damaged heart and veins and poor eyesight. Chronic smokers often cannot distinguish colours and have a form of night blindness. Buy UK Eliquid
Nicotine is highly addictive. In fact it is just as addictive as Heroin or Cocaine. The smoker’s body becomes physically and psychologically dependent on its intake of this chemical. Nicotine is carried into the lungs where it is absorbed quickly into the bloodstream, affecting many parts of the body, such as the heart, brain, blood vessels, the hormonal system, and metabolism. It is found in breast milk and can cross the placenta to the amniotic fluid and the umbilical cord, thus getting into the blood of newborn babies.
Nicotine is responsible for producing the pleasurable feelings associated with smoking. The addictive effects are why smokers crave another cigarette. As the nervous system adapts to the nicotine levels, so the smoker must increase the number of cigarettes to fuel the addiction. Quite rapidly the smoker will become tolerant to the levels of nicotine, so continues to smoke at that rate to maintain the level.
Such is the addiction that by even reducing the amount of cigarettes smoked in one day will cause withdrawal symptoms. The smoker may experience; depression, frustration, anger, sleeplessness, difficulty concentrating, tiredness, and an increased appetite. Symptoms come on within a few hours after smoking the last cigarette and peak in approximately 2 to 3 days.
Nicotine does not remain in the body for long. It has a half life of about 60 minutes. 6 hours after a cigarette, only 0.03 miligrams of the 1mg inhaled remains. The body has several means of expelling the nicotine from its system. The liver breaks down around 80% of the nicotine. The kidneys filter the nicotine from the blood to be excreted in the urine.
The tobacco companies want smokers to continue smoking and have developed ways to increase the nicotine content of cigarettes. They adjust tobacco blends by using high nicotine tobaccos to raise the nicotine concentration in lower tar cigarettes. Nicotine is added to fortify tobacco stems, scraps, and other waste materials that are then processed into reconstituted tobacco. This is used in great quantities in most major cigarette brands. The tobacco companies use genetic engineering of the tobacco plants to boost the nicotine content.
