Which symptom is commonly associated with marijuana use?

• A. Dilated Pupils
• B. Glassy Red Eyes
• C. Contracted Pupils
• D. Increased Appetite

Answer: (B)

Recognizing a classic physical sign of marijuana use. The most recognizable sign is glassy red eyes. THC causes dilation of the conjunctival vessels, so the eyes appear red and often have a glossy, bloodshot look that lasts for several hours after use. Pupillary changes aren’t a reliable indicator for marijuana—those signs aren’t consistently observed. Increased appetite is indeed a common effect, but it’s more of a behavioral/psychological effect than a straightforward physical sign you’d quickly notice in a clinical check. Because red, glassy eyes are distinctive and readily observable, they are the best match for this question.
