In the TDM Journal Club article appearing in the June 2011 issue on page 284, the first author's surname was spelled incorrectly, and the degree was incorrect. The name should appear as Aniket Natekar, BMSc.

In addition, two statistics were quoted but were put in the wrong order. When cocaethylene (CE) was found in the blood of volunteers, who were given cocaine and alcohol, there was a dose-concentration relationship between cocaine and CE. However, the Cmax was 17%, and not 2% as cited in the commentary. As well, CE concentrations were only 2% of cocaine levels in the hair of volunteers, and not a Cmax of 17% as written. In summary, the reported results are actually switched.
