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.
