title: Headache after substance abuse: a diagnostic dilemma.
abstract: An 18-year-old man inhaled a substance containing synthetic cannabinoids and 1 hour later developed a severe global headache. Imaging revealed a perimesencephalic subarachnoid haemorrhage. An angiogram suggested that a small superior cerebellar artery aneurysm was the culprit. This report discusses the, as yet undefined, relationship between "herbal highs" and intracranial haemorrhage.
