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:
“Scientific method is the way to truth, but it affords, even in
principle, no unique definition of truth. Any so-called pragmatic
definition of truth is doomed to failure equally.”
—Willard Van Orman Quine (b. 1908)
“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.”

“The definition of good prose is proper words in their proper places; of good verse, the most proper words in their proper places. The propriety is in either case relative. The words in prose ought to express the intended meaning, and no more; if they attract attention to themselves, it is, in general, a fault.”
—Samuel Taylor Coleridge (1772–1834)
