Nicotine levels fall while a person sleeps, while objects and actions on waking can also prompt a learned expectation; calling everything ‘habit’ or everything ‘withdrawal’ misses this overlap.

How to read the evidence

Planning the first sequence before bed—where cigarettes will not be, what happens after waking and how the first hour is structured—can make the trigger easier to observe and change.

What it means in practice

The timing of a first cigarette is sometimes used inside dependence assessments, but one morning urge by itself cannot diagnose a person or determine which support is appropriate.
