Abstract
This article is dedicated to the Memory of Professor Nadine Lambert, October 21 1926 – April 26 2006. There is a paradox that the amphetamine class of drugs used in the treatment of Attention Deficit Hyperactivity Disorder (ADHD) are also abused widely in society. This article reviews possible legal issues related to the topic and the historical discourse concerning addiction associated with the use of amphetamines and methylphenidate for the treatment of ADHD, Lambert's theories and the research counterclaims that are used to support the pharmaceutical manufacturer's report that ‘adequate treatment of ADHD may reduce the risk of substance abuse’. There are limitations in the Lambert studies and also limitations with other studies in the area. Further research and independent scientific and statistical analyses are required to determine any definitive conclusion. The author concludes that the claim and counterclaims cannot easily be resolved without a significant independent international inquiry.
