There was an error in an article published in the October issue of the journal (Cakic V. Smart drugs for cognitive enhancement: ethical and pragmatic considerations in the era of cosmetic neurology. J Med Ethics 2009;35:611–15). On p 613 under Performance-enhancing drugs are dangerous, it reads “Caffeine, for example, reliably increases performance in a range of sports including swimming, cycling and running at doses allowed by WADA. Yet despite being a form of “cheating” in the same vein as anabolic steroids, caffeine’s use in sport is permitted because it is relatively harmless.” It should read “Caffeine, for example, reliably increases performance in a range of sports including swimming, cycling and running. Yet despite being a form of “cheating” in the same vein as anabolic steroids, caffeine’s use in sport is permitted by WADA because it is relatively harmless.”
