"It has recently come to the attention of the DEA, the Ciba-Geigy (the manufacturer of the methylphenidate product marketed under the brand name Ritalin) contributed $748,000 to CHADD from 1991 to 1994. The DEA has concerns that the depth of the financial relationship with the manufacturer was not well-known by the public, including CHADD members that have relied upon CHADD for guidance as it pertains to the diagnosis and treatment or their children.  A recent communication from the United Nations International Narcotics Control Board (INCB), expressed concern about non-governmental organizations and parental associations in the United States that are actively lobbying for the medical use of methylphenidate for children with ADHD.  The INCB further stated that “financial transfer from a pharmaceutical company with the purpose to promote sales of an internationally controlled substance would be identified as hidden advertisement and in contradiction with the provisions of the 1971 Convention (Article 10, para 2).”
