Which of the following is listed as a symptom of acute cannabis intoxication?

• A. Conjunctival irritation/erythema
• B. Dehydration
• C. Tremor
• D. Hypoglycemia

Answer: (A)

Conjunctival irritation and redness are classic signs of acute cannabis intoxication. Cannabis causes dilation of the tiny vessels in the eye, leading to bright red, irritated-looking eyes that clinicians often recognize as a distinctive cue of recent use. This ocular finding is one of the most reliable and commonly taught indicators when assessing someone for marijuana intoxication, especially in the context of other cognitive and motor effects.

Dehydration isn't a defining feature of cannabis intoxication; while people may experience dry mouth, true dehydration is not a characteristic sign. Tremor is not typical for cannabis intoxication, and hypoglycemia is not associated with acute marijuana effects.
