United Nations Special Assmbly on Drugs 2016. In April 2016 the United nations held a Special Assembly on drugs. This resulted from several member states requesting that the original date for revisiting the so called Political Declaration and Plan of Action was moved forward from 2019 to 2016 in order to instigate a wider discussion on the current agreed UN convention framework. The outcome of UNGASS 2016 has been contraversial, but it has created a space for countries to instigate a conversation with their communities in order to feed into the final declaration in 2019.
The UK Drug Policy Commission (2012). A two year comprehensive study into drug policy formation and recommendations for future policy formation. Lots of documents here on how to make good policy and the impact that policy has on various sections of society.
