Doctors treating a baker who had a seizure at work suspected drug-abuse which the patient denied until his business partner told them that the bakery's weekly order of poppy seeds had gone up from 3 kg to 25 kg. The baker then admitted to drinking up to 2 L of tea made from about 4 kg of poppy seed every day, a practice he was introduced to during his apprenticeship. Mark King and colleagues from Victoria, Australia, report this case in a Research Letter this week, and remark on the patient's extraordinary drug tolerance since his daily consumption was the equivalent of 280 mg of morphine, On admission his blood morphine concentration was nearly 3 mg/L-heroin addicts who die of an overdose have mean concentrations of 0-6 mg/L. He was admitted to a rehabilitation programme where the poppy tea was replaced with slow-release oral morphine.
