Lead Poisoning Due to Adulterated Marijuana (Correspondence, N Engl J Med 2008:358;1641 - 1642) . One of the authors' names was inadvertently omitted in the published letter: Katharina Timper, M.D. (University Hospital Leipzig, Leipzig, Germany), should have been listed as the third author. Also, in the first footnote under Table 1, the factor for conversion of lead to micromoles per deciliter should have been 0.0049 (rather than 0.049). We regret the errors. The letter has been corrected on the Journal's Web site at www.nejm.org.
