When people quit smoking, the levels of those chemicals drop. Their bodies react by having nicotine withdrawal symptoms such as grouchiness and hunger. Nicotine from medicines increases the levels of dopamine and norepinephrine just like nicotine from cigarettes does. Chemical levels in the brain are kept level so that withdrawal symptoms are reduced. This can temporarily replace the nicotine that a person got from smoking cigarettes.
