Which of the following is a physical finding associated with chronic opioid use?

• A. Track marks
• B. Erythema multiforme
• C. Eczema
• D. Leukoplakia

Answer: (A)

Repeated intravenous opioid use leaves telltale marks from needle punctures along veins, known as track marks. These are superficial scars or darkened lines that reflect chronic injection sites, usually on the arms or forearms, and may be accompanied by skin thinning or localized inflammation. This pattern is a classic physical finding of long-term IV drug use.

Other options don’t fit the pattern: erythema multiforme is a hypersensitivity reaction that can occur with infections or certain drugs but isn’t specifically tied to chronic opioid use; eczema is a general inflammatory skin condition; and leukoplakia is a white patch on mucous membranes often linked to tobacco or irritation, not a hallmark of opioid use.
