Nicotine withdrawal is basically a term which is used to describe a situation when a person which is dependent on nicotine significantly reduces his intake of nicotine. The effects of nicotine withdrawal are mainly observed in the people who try to quit smoking because one of the most popular forms of nicotine consumption is through cigarettes smoking. A person experiencing nicotine withdrawal becomes irritable and has a craving for cigarettes which might even cause increased blood pressure, intense headache, difficulty in concentrating, weight gain, trouble sleeping and other such problems. In chronic cases of smokers when nicotine does not reach the heart, it can affect its functioning and cause heart attack which may even lead to the death of a person. The symptoms of nicotine withdrawal are mainly seen in those people who have been either smoking for a long time or have smoked very large number of cigarettes. Various different strategies are used for the treatment of nicotine withdrawal which may include use of nicotine supplements, anti smoking medicines, antidepressant medications and others. Though nicotine withdrawal is short lived and passes within a week but the real challenge lies in staying away from tobacco and beating its craving in the long term.
