After his death, the five other authors of the sixth edition renamed the book in his honour as Edwards' Treatment of Drinking Problems.
[7] Professor Edwards combined a career of developing research and knowledge on aspects of alcohol and drug problems with the promotion of community based actions.
Edwards conducted research and supported the development of new approaches to those who are homeless and also people in prison with alcohol problems.
In addition, he supported the development of community drug agencies in the late 1960s and was involved in the early work piloting community-based services for alcohol problems.
Along with Lady Ann Parkinson,[8] he supported the founding of a charity originally called Action on Addiction in 1989.
