In their annual report to the United Nations Human Rights Council, the Working Group on Arbitrary Detention (WGAD) explores the relationship between drug control and arbitrary detention. (see paras 57-62)
This report is the first time the WGAD has addressed drug control as a thematic issue within the mandate, examining drug-related detention across both administrative and criminal settings. In their conclusions and recommendations, the WGAD condemned compulsory drug detention for purposes of rehabilitation as "inherently arbitrary" and has requested the Human Rights Council to support the WGAD in conducting an in-depth study of the relationship between drug control and arbitrary detention to be submitted in 2017.
