Smoking : Your Road For Death
(Viram)
It is very difficult to quit smoking because of the addictive nature of nicotine, a drug that occurs naturally in tobacco. Nicotine is just as physically and mentally addictive as cocaine or heroin and smokers quickly become dependent on it. They then have to overcome both the physical and psychological effects of nicotine addiction in order to quit and to remain cigarette-free.The act of smoking can also develop into a routine over time. Like many repetitive habits, it can be very hard to break.Nicotine creates pleasurable feelings that make the smoker crave more. It also inhibits the proper functioning of nerve cells. As the smoker's nervous system adapts to the drug, they usually smoke more cigarettes, which in turn, raises the level of nicotine in the bloodstream. Eventually the smoker develops a tolerance to nicotine, which in turn leads to a further increase in smoking. Eventually a certain nicotine level is achieved in the smoker's body and they then smoke enough to maintain it.When a smoker tries to cut back or quit, he experiences mental and physcial withdrawal symptoms. Withdrawal symptoms can include irritability, anger, depression, tiredness, inability to sleep or to concentrate, restlessness, headaches, and increased appetite.These unpleasant symptons can cause the smoker to resume smoking in an attempt to raise the levels of nicotine in the blood to the point where the symptoms cease. Many smokers explain that the cravings they experience when they try to quit are intense.If a person has smoked for a few weeks or more, he will experience withdrawal symptoms when he tries to quit or cut back. Symptoms usually occur within a few hours of the last cigarette and peak within 48 to 72 hours. Withdrawal symptoms can last for days or weeks. The psychological addiction can persist for much longer. Smokers frequently return to the habit when under stress. They may also return to it as a form of weight control since pounds typically creep up when smoking is discontinued.
