Background: Given the increasing number of lead poisoning in opioids users and since no study has been conducted\nso far to review lead poisoning in methamphetamine (crystal) users, this study aimed to investigate blood lead level in\nmethamphetamine addicts.\nMethods: This study was conducted on 20 patients with methamphetamine poisoning and their blood lead level was\nmeasured. The subjects were selected from among patients with a history of continuous use of methamphetamine,\nwithout a history of using opiates in the past 6 months confirmed by a negative urine tests, and without a history of\nheavy metal poisoning.\nResults: Of all, 18 patients were male and the mean age was 32 �± 10 years; 17 patients were abusing the drug\nvia inhalation and three persons via oral administration. The mean blood lead level was 2.3 �± 1.1 �¼g/dL and\npoisoning was not observed in any of the cases. Blood lead level was not associated with age, sex, dosage, and\nroute of administration.\nConclusion: Although blood lead level was not at poisoning level in people who only used methamphetamine in\nIran, due to the simultaneous use of other substances and because of non-specific symptoms, lead poisoning must be\nsuspected in all cases of substances poisoning.
