Identifying smokers can often be done by observing certain physical signs and characteristics, especially those caused by chronic tobacco exposure. These signs include changes to the face, mouth, and teeth, as detailed below:
Physical Signs of Smoking
Facial Features
- Moustaches:
- In elderly individuals, especially those with white hair, moustaches can exhibit a noticeable yellowing in the center. This pattern is a strong indicator of chronic smoke exposure and is particularly visible in those with light-colored facial hair. This yellowing is due to the smoke particles accumulating in the moustache hairs over time [Figure 1].
Oral Changes
- Lips:
- Heavy smokers often develop a distinct bluish-black discoloration of the lips. This is due to changes in blood circulation and pigment deposition caused by the chemicals in cigarettes.

- Brownish-black staining from the inside, where the smoke particles accumulate behind the enamel.
- Yellow discoloration from the outside, which is caused by the tar and other components of cigarette smoke.

Summary Table: Physical Indicators of Smoking
| Feature | Characteristic |
|---|---|
| Moustaches | Yellowing in the center, especially noticeable in elderly with white hair. |
| Lips | Bluish-black discoloration in heavy smokers. |
| Teeth | Brownish-black staining from the inside and yellow discoloration from the outside. |
These physical signs provide visual clues that can help identify individuals who smoke. However, these signs are most evident in long-term or heavy smokers, and their absence doesn’t necessarily mean someone is not a smoker.
