Which physical finding is commonly associated with chronic inhalant use?

• A. Dermatitis around mouth or nostrils
• B. Jaundice
• C. Nail clubbing
• D. Photosensitive rash

Answer: (C)

Chronic inhalant use, especially sniffing solvents or adhesives, often causes irritant contact dermatitis around the mouth and nostrils from repeated exposure. The skin in that perioral region becomes red, cracked, scaly, and irritated as the chemicals contact the skin directly during sniffing. This perioral dermatitis is a classic, visible clue of inhalant abuse.

Jaundice would point to liver injury, which isn’t a typical, defining feature of inhalant use. Nail clubbing suggests long-standing lung disease with chronic hypoxemia, not a common consequence of inhalant abuse. A photosensitive rash isn’t characteristic of inhalant exposure either. So the perioral dermatitis around the mouth and nostrils best reflects the pattern of irritation from chronic inhalant inhalation.
