By which symptom is it possible to identify a long-term cocaine user?

A. clear, constricted pupils Cocaine is a stimulant and causes dilated (not constricted) pupils during intoxication. Constricted pupils are more characteristic of opioid use. B. red, irritated nostrils Snorting cocaine repeatedly causes irritation to nasal passages, leading to redness, inflammation, and even nosebleeds or septal perforation. C. conjunctival redness This is more commonly seen with marijuana use, not cocaine. D. muscle aches Not a hallmark symptom of long-term cocaine use.
