Withdrawal symptoms and nicotine
A smoker's nervous system becomes accustomed to functioning with nicotine.
When you stop smoking, the reduced nicotine intake will disturb the balance of the central nervous system, causing withdrawal symptoms.
The most common withdrawal symptoms are:
cravings for tobacco
irritation
anger
increased appetite
weight gain
concentration problems
depression or low mood
tiredness
constipation
restlessness
insomnia
anxiety.
Fortunately, the majority of these symptoms tend to disappear after a few of weeks.
Some people may experience cravings, concentration problems and an increased appetite over a longer time period.
Nicotine affects every part of the nervous system, including the pleasure centre of the brain.
A variety of different brain chemicals are altered each time you smoke.
Did you know?
When you inhale, it takes just seven seconds for nicotine to reach the brain.
Drugs that enter the brain rapidly tend to be more addictive than drugs which get in more slowly.
smoking stimulates and increases concentration
smoking helps them to relax and deal with stress.
As a smoker, you might smoke some cigarettes to wake yourself up (eg the first one in the morning) and others to help you relax or calm yourself down when stressed or bored.
Although nicotine is primarily a stimulant drug, it works differently in different areas of the brain. For example, it soothes the limbic system, one of our most important emotional centres.
Withdrawal from nicotine creates a hypo-functional state in the body which results in low brain activity. Other withdrawal symptoms that last for 3 to 7 days include irritability, insomnia, acute headaches, restlessness, depressed mood, fatigue, increased appetite and dizziness.
Repeated exposures to nicotine, followed by withdrawal, induce a persistent increase in brain reward function and sensitivity to the nicotine and endurance of the effects.
Craving for nicotine is often experienced in the couple of months after quitting.
There are many other factors like depression that are induced by nicotine withdrawal - for example, individuals who are more susceptible to depression use nicotine to mask this disease and, when quitting, have a 25% chance of becoming more depressed when they quit, a risk which endures for 6 to 7 months
