Doctors Can Detect Smoking Habits Through Subtle Physical Cues

Doctors can often detect subtle physical cues indicating a smoking habit even before an individual admits to it. These signs, which may appear early, include changes in skin tone and texture, fine lines around the mouth, nail circulation, breathing patterns, and voice hoarseness. While no single sign is definitive, a combination of these physical indicators can suggest smoking. The lungs and blood vessels are noted to retain the longest memory of smoking's effects.
