A 39-year-old previously healthy man experienced diffuse, progressive, peripheral arterial spasm 36 hours after the ingestion of concentrated high-grade 4-bromo-2,5-dimethoxyamphetamine. Vasospasm responded readily to intra-arterial and intravenous vasodilators. Excessively high doses of this hallucinogen may cause diffuse arterial spasm.
