Nicotine withdrawal is the effect that nicotine dependent individuals feel after they discontinue or decrease nicotine intake. Nicotine is an addictive substance found most commonly in cigarettes, cigars, pipe tobacco and chewing tobacco. The symptoms of nicotine withdrawal usually appear approximately 2 or 3 hours after last dose of nicotine. The common symptoms of nicotine withdrawal are an intense craving for nicotine, anxiety, drowsiness, depression, headaches, increase in appetite, weight gain and difficulty with concentration. Approximately 50% of the smokers who quit usually relapse within a year. However the more attempts a smoker makes, the greater the likelihood of quitting, because each attempt makes an individual more familiar with nicotine withdrawal symptoms.

Famous quotes containing the word definition:
“No man, not even a doctor, ever gives any other definition of what a nurse should be than this—”devoted and obedient.” This definition would do just as well for a porter. It might even do for a horse. It would not do for a policeman.”
—Florence Nightingale (1820–1910)
“It is very hard to give a just definition of love. The most we can say of it is this: that in the soul, it is a desire to rule; in the spirit, it is a sympathy; and in the body, it is but a hidden and subtle desire to possess—after many mysteries—what one loves.”
—François, Duc De La Rochefoucauld (1613–1680)
“The man who knows governments most completely is he who troubles himself least about a definition which shall give their essence. Enjoying an intimate acquaintance with all their particularities in turn, he would naturally regard an abstract conception in which these were unified as a thing more misleading than enlightening.”
—William James (1842–1910)
