Abstract
A 42-year-old man who was in rehabilitation for intravenous substance abuse presented with a three-month history of seizures and incoordination. Other symptoms included dysarthria, a hesitant pattern of speech, myoclonic jerks, postural tremor, emotional lability, and fluctuating short-term memory. On questioning he admitted that for four years he had been concentrating his methadone preparation, which was diluted with a grape-flavored drink, by heating it in an uncoated aluminum pot. He would then reconstitute the residue for intravenous injection. His serum aluminum level was 6650 nmol per liter (reference interval, <400). The patient reported that he did not use antacids, had had no occupational exposure to aluminum, and did not use the aluminum pot for cooking.
