In 1992, the PSA launched the "WHO/UNICRI Cocaine Project", which according to a press release in March 1995 was the largest global study on cocaine use ever undertaken. The conclusions strongly conflicted with accepted paradigms so that almost as soon as the Briefing Kit started to circulate in the UN corridors, USA officials used their full weight to prevent the release of the study.Years of work and hundreds of pages of valuable facts and insights about coca and cocaine by more then 40 researchers were, in effect, "burned".
The UN Commission considers to bring ketamine under the control of the 1971 Convention on Psychotropic Substances contrary to WHO recommendations. The 58th Session of the UN Commission on Narcotic Drugs (CND) in March 2015 has been asked to consider a Chinese proposal to place ketamine – an essential medicine used for anaesthesia – in Schedule I of the 1971 Convention (E/CN.7/2015/7 and E/CN.7/2015/81). Ketamine is the only available anaesthetic for essential surgery in most rural areas of developing countries, home to more than 2 billion of the world’s people. Scheduling ketamine under any of the 1971 treaty schedules will reduce its availability and further deepen the already acute crisis of global surgery.
