Adverse Effects of the Use of Unusual Phenethylamine Compounds Sold as Illicit Amphetamine

Abstract

A 40-year-old man, who had regularly taken illicit amphetamine by intra-nasal inhalation for several years without ill effects, was admitted to hospital with signs of massive adrenergic overstimulation shortly after inhaling material which he had purchased in the belief that it was amphetamine. The administration of the beta-blocker practolol produced a paradoxical increase in blood pressure. After his discharge from hospital he suffered disabling feelings of anxiety for several weeks. Analysis of a sample of the material showed it to contain p-methyl amphetamine and N, p-dimethyl amphetamine.
