Craving: one episode
An urge rises and falls. Its length and intensity vary, and thinking about it can make the episode feel longer than a stopwatch measurement.
Withdrawal: a changing background
Irritability, concentration difficulty, sleep change, restlessness, low mood and appetite change can occur after stopping nicotine. The mix and duration differ between people.
Cue: a learned signal
Places, actions, people and emotions repeatedly paired with smoking can prompt an urge. This learned association can persist after nicotine has left the blood.
What to keep in mind
Common questions
Can I have withdrawal without a strong craving?
Yes. People experience different combinations of symptoms.
Does a late craving mean withdrawal restarted?
Not necessarily. A familiar cue or stressor can produce an urge without recreating the entire early withdrawal period.
