For the revised paperback edition, as well as correcting and updating the text and references, the authors included an important postscript on the charges of falsification of evidence and their subsequent refutation which made up the Sobell affair. The wealth of other material presented in Controlled Drinking supports the authorsβ conclusions even if the Sobellsβ work were ignored. However, this revised edition was made more useful for student and professional readers by the postscriptβs discussion of the controversy surrounding the most widely known and quoted controlled drinking trial at the time.
