Question

Magnan's symptom is related to:

• A. Cocaine poisoning
• B. Cannabis
• C. Opium
• D. Alcohol

Hint:

Imaginary bugs crawling under the skin point to one stimulant drug.

Answer 1

The Correct Option is A

One-line clinical pearl: Magnan = cocaine bug. The patient with chronic cocaine use develops formication, a tactile hallucination of insects or sand crawling beneath the skin, and scratches until ulcers form. Link the name to the drug and the answer is immediate. Run a quick check on the distractors: cannabis gives euphoria, distorted time sense and the run-amok picture, opium causes the classic pinpoint pupils and respiratory depression, and alcohol withdrawal gives delirium tremens with visual hallucinations rather than the under-the-skin crawling sensation. None of these is the cocaine bug. So Magnan's symptom belongs to cocaine poisoning, option 1.
