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:
“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)
“It’s a rare parent who can see his or her child clearly and objectively. At a school board meeting I attended . . . the only definition of a gifted child on which everyone in the audience could agree was “mine.””
—Jane Adams (20th century)
“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)
