Definition
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:
“The very definition of the real becomes: that of which it is possible to give an equivalent reproduction.... The real is not only what can be reproduced, but that which is always already reproduced. The hyperreal.”
—Jean Baudrillard (b. 1929)
“The physicians say, they are not materialists; but they are:MSpirit is matter reduced to an extreme thinness: O so thin!—But the definition of spiritual should be, that which is its own evidence. What notions do they attach to love! what to religion! One would not willingly pronounce these words in their hearing, and give them the occasion to profane them.”
—Ralph Waldo Emerson (1803–1882)
“Although there is no universal agreement as to a definition of life, its biological manifestations are generally considered to be organization, metabolism, growth, irritability, adaptation, and reproduction.”
