Withdrawal from nicotine
Nicotine withdrawal involves irritability, headache, and craving for cigarettes or other sources of nicotine. These symptoms occur when a nicotine-dependent individual suddenly stops smoking or using tobacco, or cuts back on the number of cigarettes or tobacco products used.

Almost all people who try to quit have some form of nicotine withdrawal. Generally, people who smoked the longest or smoked a greater number of cigarettes each day are more likely to have withdrawal symptoms.
People who are regular smokers tend to have particularly strong cravings and worsening of withdrawal symptoms at certain times, places, or situations associated with smoking.
